Wettest Communities

Prince Rupert's average of 3111 millimetres (mm) (over ten feet) of precipitation a year earns it the reputation as Canada's wettest city. Nearly all of the moisture in the northern British Columbia, ocean port city falls as rain.

But several towns on BC's rainy west coast receive much more precipitation. Hartley Bay measures an incredible 4549 mm, or nearly 15 feet, of water pelting down each year. The Gitga'at village of 180 year-round residents sits at the confluence of Grenville and Douglas Channels, about 140 km south of Prince Rupert.

Average annual precipitation for other very wet towns in British Columbia:

Location	millimetres
Holberg	3912
Port Renfrew	3671
Tofino	3306
Gold River	2846

Rainier yet are some of the weather stations located at fish hatcheries and lighthouses scattered along coastal BC. Among these, Henderson Lake, located between Port Alberni and Ucluelet on western Vancouver Island ranks as the wettest. The fish hatchery there received 9082 mm (nearly 30 feet) of precipitation in 1997.

Rest of Canada

The Atlantic coast gets nowhere near the amount of precipitation that deluges Canada's Pacific coast.

A few places on BC's west coast have received more than 254 mm (10 inches) of rain in a single day, more than some areas of Canada get in a year.

These are some of the biggest downpours ever recorded for a single day in Canada:
