How much and how often does it snow in Victoria?

Victoria gets less snow than any other city in Canada.  The 30-year (1991-2020) average annual snowfall for Victoria is 16 cm.  That's significantly less than nearby Vancouver, which receives an annual average of 34 cm, as measured at the Vancouver Airport.  

The core area of Greater Victoria also gets significantly less snow than outlying areas such as Langford or the Saanich Peninsula.  The Victoria Airport, located 25 km north of Victoria, averages 34.8 cm of snow annually - more than double what the City receives.  It's quite common for there to be snow in the Westshore or the Saanich Peninsula, while there is little or no snow in the core area.  This is due to the generally milder temperatures near the Strait of Juan de Fuca and the lower precipitation amounts in the core thanks to the Olympic Mountain rainshadow.

The table below summarizes the average snowfall and snow cover (days with at least 2 cm of snow on the ground) in Victoria, by month.  December has the highest amount of snowfall (6.3 cm), although both December and January have on average, a similar number of days with snow on the ground (1.2-1.3 days).


While the table above shows the 30-year averages for snow in Victoria, there is a lot of variability from year to year.  The chart below shows the annual winter snowfall over the past century.  The chart shows 3 years (1949/50, 1968/69, and 1996/97) when Victoria received more than 100 cm of snow.  In fact, the snowiest winter on record for Victoria was 1915/16 (not shown on the chart) when Victoria received an astonishing 195.6 cm of snow!  On the other hand, there have been 7 winters in the past 125 years (6%) with no snow, and 33 winters (26%) with less than 5 cm of snow.  

The chart also shows the rolling 30-year average snowfall and 30-year median snowfall (starting with the 30-year period from 1898/99 to 1927/28 and finishing with the most recent 30-year period of 1993/94 to 2022/23).  Because the average snowfall tends to be skewed by the occasional large snowfall, the median snowfall (11.5 cm for 1991-2020) is lower than the average snowfall (16.0 cm). 


Even the 30-year average snowfall has fluctuated significantly over time.  From a low point of 19.9 cm for 1918/19 to 1947/48, the 30-year average snowfall reached a high point of 37.5 cm for 1946/47 to 1975/76.  Since then, average snowfall has generally been decreasing, with climate change likely contributing to this trend.  For the most recent 30-year period (1992/93 to 2021/22), snowfall averaged 17.4 cm (slightly higher than the 1991-2020 average).  

The chart below shows the trend in number of days annually with at least 2 cm of snow on the ground.  Snow on the ground has only been measured in Victoria since 1955, so the period of record is shorter.  As with snowfall totals, the days with snow on the ground varies considerably from year to year.  In 19 of the past 68 winters (28%), there have been no days with 2 cm or more snow on the ground.  On the other extreme, there have been 4 winters with more than 15 days with snow on the ground - including one winter (1968/69) when there was 30 days with snow on the ground!  The average number of days with snow on the ground has generally decreased over time, from about 5 days for the 1955/56 to 1984/85 period down to about 3.8 days for the most recent 30-year period (1992/93 to 2021/22), which again was slightly higher than the 1991-2020 average.



Another way to look at the snowfall data is to use quintiles.

  • The bottom quintile (the 20% of winters with the least snowfall) had an average snowfall of 1.2 cm and 0 days with snow on the ground.

  • The next quintile averaged 7.3 cm of snow and 0.7 days with snow on the ground.

  • The middle quintile averaged 16.5 cm of snow and 3.0 days with snow on the ground.

  • The next quintile averaged 30.3 cm of snow and 5.4 days with snow on the ground.

  • The top quintile (the 20% of winters with the most snowfall) had an average of 73.9 cm of snow and 15.2 days with snow on the ground.

You sometimes here about a big snow storm in another city dumping "a month's worth of snow" in a day or two.  Because snow is so infrequent in Victoria, it's not only very common to get a month's worth of snow all at once, but it's also common to get a full season's worth of snow in one storm.  For example, over the past 30 years, Victoria has received 76% of its total winter snowfall in a single two-day period.  During nearly one third of those years, Victoria received more than 95% of its seasonal snowfall in a single storm.

Other locations in the region have also seen a decline in average snowfall over the past few decades.  The chart below compares the trend in 30-year average snowfall in Victoria with other nearby locations (starting with the 30-year period from 1941/42 to 1970/71 and ending in the most recent 30-year period of 1993/94 to 2022/23).  All the locations have declined over this period.  Average snowfall levels in Victoria have trended quite closely to the pattern for Seattle.  By contrast, the Victoria Airport (in North Saanich) and the Vancouver Airport have significantly higher average snowfall levels, but they have also followed a declining trend.

Fall 2022: an abrupt shift from warm and dry to cool and wet

 Meteorological fall is from September 1 to November 30.  Fall in Victoria nearly always transitions from warm and dry in September to cool and wet in November, but in 2022 the transition was very abrupt.  

Overall, the mean fall temperature at Victoria Gonzales was 11.8 degrees, which is 0.6 degrees warmer than the 30-year average.  September was the second warmest on record at Victoria Gonzales, while October was the warmest on record (2.2 degrees above normal).  However, November was tied for the 5th coldest on record (2.1 degrees below normal).  

The chart below shows the daily maximum and minimum temperatures at Victoria Gonzales during fall 2022, compared with the 30-year averages.  From September 1 to about October 20, temperatures were consistently above normal.  There was then an abrupt shift, with temperatures much cooler than normal for the remaining 6 weeks of fall.  This included two brief cold snap, in early November and again in late November, when overnight temperatures dipped below freezing.

Daily Max & Min Temperature at Victoria Gonzales

Victoria typically experiences 9.7 days each fall when the maximum temperature exceeds 20 C.  In 2022, there were 25 such days.  Victoria usually only averages 1.5 days each fall when the maximum temperature exceeds 25 C.  In 2022, this occurred on 4 days this fall: Sept. 6th, 9th and 10th, and again on October 2nd. The maximum temperature this fall was 25.8 C on September 10th.

On the other hand, Victoria typically only experiences 0.9 days each fall when the overnight low temperature falls below freezing.  In 2022, there were 4 such days, the coldest being -2.2 C on November 29th.  


Victoria received 167 mm of rain from September to November, 26% less than the 30-year average fall rainfall of 227 mm.   

Victoria had 23 days with measurable rainfall this fall, well below the normal 37.8 days.  There was no measurable precipitation from September 1 to October 20.  Then 9 of the last 11 days in October had rainfall, followed by 14 days in November.   Normally, Victoria averages 7.8 days with measurable rain in September, 12.8 days in October, and 17.4 days in November.  


The chart below shows daily precipitation during fall 2022, and compares the cumulative precipitation with the 30-year average.   The fall started off extremely dry, with no measurable rain until October 21.  A rainy spell in late October/early November meant that fall rainfall was almost normal by November 7.  This was followed by another dry spell (a two-week period with only a few days of very light rain, less than 1 mm), before rain returned at the end of the month.  The wettest day of the fall was October 30th, with 40.6 mm of rain.  

Daily & Cumulative Precipitation at Victoria Gonzales

There were also two short periods of light snow in Victoria during November.  On November 7th, there was 2 cm of snow and on November 29th, there was another 1 cm of snow that quickly turned to rain and melted by noon that day.

An extraordinary drought

 Victoria is known for its summer droughts.  It is the driest major city in Canada - by far - during the summer months, with an average of 47 mm of rain during June to August combined.  It is also common to get long stretches with little or no rainfall during the summer.  On average, Victoria gets 31 consecutive days with no measurable rainfall each summer, and 42 consecutive days with less than 1 mm of rainfall.

However, the past three months have really been extraordinary.  From July 19 to October 20 - a period of 94 days - there have only been 3 days each with just a barely measurable 0.2 mm of rain (August 10, September 4, and September 28) at Victoria Gonzales.  That's a total of just 0.6 mm of rain in the past 3 months!  The nearby weather station at the University of Victoria has been even drier, with just 0.4 mm of rain over the same period.

This has been the driest 90-day period ever recorded at Victoria Gonzales, as shown in the chart below, easily beating the old record of 2.8 mm, from May 25 to August 22, 1951.  Note that most of these record dry periods tend to be centered on July and August, the two driest months in Victoria.  However, 3 of the 11 driest periods, include this year's, have extended into mid-October.


This record-breaking drought has not just impacted Victoria; it has affected all of southwestern B.C.  The chart below shows the total rainfall for various locations in southern B.C. over the past 3 months. As is often the case, Victoria has been the driest location, but most locations have been extraordinarily dry.  Keep in mind, that normal rainfall during this period is 91 mm at Victoria Gonzales and 231 mm at Vancouver Harbour.  


Not only has this period been the driest 3-month period ever recorded in Victoria (with 120 years of record-keeping at Victoria Gonzales), but it is also likely the driest 3-month period ever recorded in any major Canadian city.  The driest 3-month period ever recorded for some other Canadian cities includes 1.3 mm for Edmonton, 2.9 mm for Calgary, 6.1 mm for Vancouver Airport, and 37.9 mm for Toronto

In addition to being dry, it has also been a very warm 3 months.  The chart below shows the daily maximum and minimum temperatures at Victoria Gonzales during the drought period (July 19 to October 19), compared with the 30-year average.  With just a few exceptions, temperatures have been above normal.  The average daily maximum temperature for the period was 21.3 C -  nearly 3 degrees above the historical average of 18.4 C.  In addition, the average daily maximum temperature for the period in 2022 (21.3 C) is more than 1 degree warmer than the previous highest average maximum of 20.1 C for the same period in 1998.

Summer 2022 was warmer and slightly wetter than normal

 Meteorological summer consists of June, July, and August.  Summer 2022 started out wetter than normal, with close to normal temperatures in June and July. This was followed by a much warmer and drier than normal August.  Overall, the summer was warmer and about 10% wetter than normal this year in Victoria.  

The mean temperature this past summer at Victoria Gonzales was 16.3 degrees, which is 0.5 degrees above the 30-year average.  Summer 2022 was tied for the 8th warmest in Victoria since record-keeping began at Gonzales Observatory in 1914.  While June and July were just slightly above normal, August was the warmest on record in Victoria: 1.3 degrees above normal.  

The average daily high temperature this summer was 20.5 C (versus the normal of 20.0 C) while the average daily minimum was 12.0 C (normal 11.5 C).

Minimum overnight temperatures were generally have normal during summer 2022, especially in August. The coolest temperature during the summer was 8.8 C on June 15th.


Daily Max & Min temperatures, summer 2022

Victoria had 13 days with measurable rainfall this summer, just less than the normal 14.8 days.  There were 8 days with measurable rain (>0.2 mm) in June, 5 in July, and none in August.  


The chart below shows daily precipitation during summer 2022, and compares the cumulative precipitation with the 30-year average.   June was very wet, with the summer's wettest day occuring on June 9th, with 19.2 mm of rain.  In fact, this was the wettest summer day at Victoria Gonzales since 2005.  July 3rd was also a wet day, with 12.8 mm of rain.  Those two days accounted for more than 60% of the summer's rainfall.

Daily & Cumulative Rainfall in Victoria, summer 2022


The chart below compares the rainfall amounts in Victoria this summer with other locations in the region.  As is typically the case, Victoria Gonzales had the lowest amount, with a total of 52 mm.  The Victoria Airport received 68 mm.  Vancouver received 103 mm - about twice as much as Victoria (Vancouver typically receives about 3 times as much rain in the summer as Victoria).  Seattle received 76 mm.    

Regional Comparison of Summer 2022 Rainfall

Summer 2022 slightly less sunny than normal.  June and July were both cloudier than normal, while August was sunnier than normal.  

The table below shows the number of mostly sunny days (>80% of possible sunshine), partly cloudy days (20-80% of possible sunshine), and mostly cloudy days (<20% of possible sunshine).  There were more mostly sunny days than normal (51 in 2022 compared with the normal of 45 days).  However, there were also more mostly cloudy days than normal (14 days compared with the normal of 12).  More than half of the summer's mostly cloudy days were in June.

Spring 2022: cooler and a bit wetter than normal

Meteorological spring consists of March, April, and May.  Thanks to a very chilly April and May, Spring 2022 was the coolest spring in Victoria since 2011.  Spring 2022 was also a bit wetter than average, especially during April.

The mean temperature this past spring at Victoria Gonzales was 9.0 degrees (ave. high 11.9 & ave. low 6.0), which is 1.1 degrees below the 30-year average of 10.1 C.  March was 0.2 degrees warmer than normal, but April and May were both 1.8 degrees cooler than normal.   Both April and May were the 2nd coldest in the past 30 years, with only 2011 being colder.     

The chart below shows the daily maximum and minimum temperatures at Victoria Gonzales during spring 2022, compared with the 30-year averages.  Temperatures were fairly normal until early April, but the second half of spring saw temperatures that were consistently lower than normal.  The highest temperature during the spring 2022 was 17.3 C on April 7, whereas the average warmest spring day at Victoria Gonzales is 25 C.  Victoria Gonzales normally sees 5.2 days during spring with temps above 20 C, and 0.8 days with temps above 25C.  The warmest temperature in May this year was just 16.6 C - the coldest May maximum ever recorded at Victoria Gonzales.


There were no days during Spring 2022 when the overnight low fell below freezing.  On average, Victoria sees just 0.6 days each spring with a low temperature below 0.  The coldest temperature of the spring was April 12th when the temperature dropped to 0.3 degrees.

The cold winter of 2021-22 in Victoria

Meteorological winter is from December 1 to February 28.  Winter 2021-22 in Victoria was much colder than average.  It was also rainier and much snowier than average.  

This past winter was the coldest in the past 5 years, and the 4th coldest in the past 30 years.  The mean temperature at Victoria Gonzales was 4.6 degrees, which is 1.2 degrees colder than the 30-year average of 5.8.  The average daily maximum for winter 2021-22 was 6.7 degrees , while the average daily minimum was 2.5, both of which were 1.2 degrees colder than the 30-year averages of 7.9 max and 3.7 min.  December was the coldest month, with a mean of 2.9 degrees, making it the 9th coldest December in the past 124 years, and 2.7 degrees colder than the long term average.  While January and February were closer to average, both were about 0.5 degrees colder than normal.


The chart below shows the daily maximum and minimum temperatures at Victoria Gonzales during winter 2021-22, compared with the 30-year averages.  The temperature trend is distinguished by two arctic outbreaks, resulting in a major cold snap in late December, and a second less severe cold snap in late February.  The rest of the winter was fairly close to average.  The warmest day of the winter was recorded on the first day of the season, with a high of 12.7 C on December 1.  

Daily Max & Min Temps at Victoria, winter 2021-22


The December cold snap was one of the most severe in Victoria in recent memory.  The overnight minimum dropped as low as -9.7 C on December 27, which was Victoria's coldest recorded temperature in 36 years.  There were 4 consecutive days when the temperature did not rise above freezing, tied for the 7th longest such streak in the past 124 years in Victoria.  

Victoria Gonzales saw 14 days this winter with overnight lows below freezing, versus the long-term average of 9.6 days.  Eight of these days occurred consecutively, from Dec. 25 to Jan. 1, during the late December cold snap.  A further 5 days occurred consecutively during the late February cold snap.

Victoria received 302 mm of precipitation from December to February, 13% more than the normal winter precipitation of 267 mm.  December and January were both about 25% wetter than normal, but February was slightly drier than normal.  February would have been much drier than normal, if not for 36 mm of rain during the last two days of the month.  Up until Feb. 26, Victoria had received only about 15 mm of rain in February - about 25% of normal.  

Winter 2021-22 saw more days with measurable precipitation than the 30-year average.  There were 55 days with greater than 0.2 mm of precipitation versus the long term average of 46.4 days.  December saw 24 days with precipitation (versus the normal 16.8), January saw 18 days (close to the normal 16.6), and February saw 13 days (right on the normal 13.0 days).  There were also more heavy precipitation days during winter 2021-22 than normal: 5 days with more than 25 mm of precipitation vs. the long range average of 1.5 days.  


The chart below shows daily precipitation during winter 2021-22, and compares the cumulative precipitation with the 30-year average.  The winter was consistently wetter than average until about January 20.  This was followed by about 5 weeks with much drier than normal weather, then finally more heavy rain during the last 2 days of the season.   The wettest day of the winter was January 6, when 33.9 mm fell.  



Daily & Cumulative Precipitation in Victoria, winter 2021-22



The chart below compares the precipitation amounts in Victoria this winter with other locations in the region.  Thanks to the Olympic Mountain rainshadow, Victoria Gonzales is typically much drier than other locations in the region.  However, continuing a recent trend of the past couple of years, the differences were less than normal this winter.  Victoria had 113% of normal winter precipitation, while Victoria Airport had just 94% of normal and Vancouver had only 83% of normal.  Like Victoria, Seattle had above normal precipitation during winter 2021-22.  

  
Winter Precipitation in the Region, 2021-22



Victoria received 30 cm of  snow in winter 2021-22.  That's more than double the normal winter snowfall of 13.8 cm. Half of this winter's snow fell in December (16 cm), and most of the rest (12 cm) fell in January.  Victoria had 10 days this winter with at least 2 cm of snow on the ground.  That's 3 times the normal 3.2 days with snow on the ground.

Overall, winter 2021-22 was  close to normal for sunshine.  December and February were a bit sunnier than normal, while January was a bit cloudier than normal.

The table below shows the number of mostly sunny days (>80% of possible sunshine), partly cloudy days (20-80% of possible sunshine), and mostly cloudy days (<20% of possible sunshine) during winter 2021-22.  Overall, there were close to the normal amount of mostly sunny days, while there were more than average partly cloudy days, and fewer than average mostly cloudy days.  December had fewer than normal sunny days, but more partly cloudy days.  February had more than normal sunny days and fewer than normal mostly cloudy days.

2021 was a year of weather extremes in Victoria

2021 was an extraordinary year for weather in Victoria.  Below is a list of just some of the weather extremes experienced in 2021: 

  • All-time hottest temperature ever recorded: 39.8 C on June 28, shattering the old record by almost 4 degrees.
  • Warmest June on record, with mean temperature of 16.6 C.
  • Coldest temperature recorded in 36 years: -9.7 C on December 27.
  • Four consecutive days when the temperature did not rise above freezing (Dec. 26-29) – the longest stretch in 36 years.
  • Biggest range of temperatures ever recorded in one year: 49.5 degrees C.

  • The wettest year on record, with an estimated 953 mm of precipitation.  The old record was 944.6 mm in 1933.  
  • There were 8 days with 25 mm or more precipitation, the most ever recorded at Victoria Gonzales.
  • Wettest meteorological fall (Sept. 1 to Nov. 30), with 510 mm. The rainfall during those 3 months was equal to more than 80% of Victoria’s average annual rainfall.
  • Not one, but two of the 10 all-time wettest days ever recorded in Victoria: 72.6 mm on November 15 (7th wettest) and 71.4 mm on October 28 (9th wettest).
  • Tied for the driest July on record with 0 mm (there have been 6 other Julys with no rainfall).
  • 3rd longest streak with no measurable rain: 53 days from June 15 to August 6.

Truly amazing!

The mean temperature for 2021 (10.6 C) was close to the 30-year average of 10.7 C, but there was a lot of variation during the year.

Six months had higher than normal temperatures (January, April, June, July, August, and November).  June was the warmest on record (16.6 C - a full 2 degrees above normal), while the summer overall was the 6th warmest in 123 years.  On the other hand, six months were cooler than average (February, March, May, September, October, and December).  

The hottest temperature of 2021 - and the hottest temperature ever recorded in Victoria - was on June 28, with a temperature of 39.8 C.  That was about 20 degrees above the normal temperature for the date, and nearly 4 degrees hotter than the previous all-time temperature record for Victoria.  There were 3 days in 2021 with daily maximums above 30 C, compared with the normal of 1.1 days.  There were 15 days with daily maximums above 25 degrees, compared with the average of 9 days.    

The coldest temperature of 2021 was -9.7 C on December 27.  That was the coldest temperature recorded at Victoria Gonzales since November 1985 - more than 36 years.  There were 13 days in 2021 when the temperature went below 0, significantly higher than the long-term average of 9.5 days.  Of those days when temperatures dropped below freezing, 6 occurred consecutively in February, while the other 7 occurred consecutively at the end of December.  Victoria also saw 4 consecutive days when the temperature did nor rise above zero - the longest such stretch since November 1985.

The chart below shows the daily maximum and minimum temperatures at Victoria Gonzales in 2021, compared with the long-term normal temperatures.  The most prominent variations from normal were the heat wave in late June and the cold snap in late December.  As a result of these extreme events, Victoria Gonzales experienced its largest range of temperatures ever recorded in a single year in 2021 - a range of 49.5 degrees between the 39.8 C on June 28 and the -9.7 C on December 27.  The average temperature range in Victoria is about 35 degrees, while the old record was 45.6 degrees in 1968.




2021 was the wettest year on record at Victoria Gonzales, with an estimated 953 mm of precipitation, 45% more than the long-term average of 656 mm.  The old record was 944.6 mm in 1933.  The record rain in 2021 followed 2020, which at the time was the wettest year in 20 years in Victoria, with 837 mm.   The fall was especially wet, in fact it was the wettest fall on record in Victoria, with 510 mm of rain from September 1 to November 30.  Victoria saw 633 mm - an entire year's worth of precipitation - in the last 4 months of the year.

The chart below shows daily and cumulative precipitation at Victoria Gonzales for 2021.   It was really only in the last 4 months of the year that precipitation was much above average.  In fact, the summer was the 6th driest on record, with just 16 mm of rain from June 1 to September 30.  This included a 53-day streak with no measurable precipitation from June 15 to August 6 - the third longest dry streak on record in Victoria. 



There were 145 days with measurable precipitation in 2021, compared with the normal of 132 days.  There were two days in 2021 that were among the 10 wettest days ever recorded in Victoria: 72.6 mm on November 15 and 71.4 mm on October 28.  There were 8 days with more than 25 mm of rain in 2021, the most on record at the Victoria Gonzales location, and far higher than the average of 2.9 days annually.  

The chart below compares annual precipitation at Victoria Gonzales in 2021 with other locations in the region.  Thanks to its rainshadow location, Victoria is typically drier than most other locations, and while that was still the case in 2021, the difference was not as much as it usually is.  That's because precipitation at Victoria Gonzales was 45% above normal in 2021, while it was just 8% above normal at the Victoria Airport (in North Saanich) 4%  above normal in Vancouver, and 11% above normal in Seattle.  Looking at this another way, the Victoria Airport typically receives more than 36% more precipitation than Victoria Gonzales, but in 2021 it got just 1% more.


Comparison of Annual Precipitation in 2021

Victoria received 44 cm of snow in 2021, nearly triple the average of 16 cm.  2021 was the snowiest year in Victoria since 1996.  There was 28 cm of snow in February, and a further 16 cm in December.  There were 10 days in 2021 with at least 2 cm of snow on the ground, 4 in January and 6 in December.  That is nearly 3 times the annual average of 3.5 days with snow on the ground.


Sunshine was slightly above average in Victoria in 2021 thanks to above average sunshine in June and July, as well as in March and April.  On the other hand, the fall months were cloudier than normal.  

The table below shows the distribution of mostly sunny, partly cloudy, and mostly cloudy days in 2021. There were 123 mostly sunny days, slightly above the average of 121.  There were 139 partly cloudy days compared with the average 132 days.  Finally, there were 103 mostly cloudy days, fewer than the average of 113 days.
