The amount of precipitation a metropolitan area receives can vary considerably from neighbourhood to neighbourhood. Topography particularly affects rainfall in the Vancouver region, which sprawls across a flat river delta to the foot of a coastal mountain range.
The precipitation data given here for Vancouver are measured at the airport, located on an island in the Fraser River. But not far from there, at the base of Grouse Mountain on Redonda Drive in North Vancouver, rain gauges fill much higher. The North Vancouver weather station averages 2477 mm of precipitation a year, twice the amount that falls at the Vancouver airport.
