Thanks to its southeastern location, precipitation at Victoria Gonzales is strongly impacted by the Olympic Mountain rainshadow. That influence tends to lessen the further north and west you go in the Greater Victoria region. Thus, when we've stated on the blog that Victoria gets less rainfall than most cities in Canada, that is based on rainfall in Victoria Gonzales, and is not necessarily true for some of the wetter parts of the region.
Below is a chart that compares average annual precipitation at various locations in Greater Victoria with major cities across Canada. As you can see, annual precipitation at both Victoria Gonzales (608 mm) and the University of Victoria (643 mm) is relatively low. Across Canada, only cities in the B.C. Interior and on the Prairies are drier. In fact, just 18% of Canada's urban population lives in cities with lower annual precipitation than these two locations. Esquimalt Harbour (861 mm) and the Victoria Airport in North Saanich (883 mm), fall more in the middle of the pack among Canadian cities, with roughly half of Canada's urban population living in cities that are drier than these locations. Meanwhile, Langford (1133 mm) and Sooke (1236 mm) get more annual precipitation than most cities in Canada: only cities in southwestern B.C., parts of Quebec, and Atlantic Canada get more precipitation. In fact, 81-86% of Canada's urban population lives in cities that are drier than these locations.
