North America's Wettest Place

Henderson Lake on Canada's south-central Vancouver Island is the rainiest spot in North America with an average precipitation of 6,903 mm (271.8 in). In 1997 it received a record 9,307 mm (366.4 in) of rainfall, the wettest spot on the continent that year and an all-time record for Canada.

The temperate rainforest belt along the Pacific Northwest coast consistently receives more rainfall than any other North American region, although some limited areas within the Costa Rican rainforest may average up to 240 in. (6,100 mm).
