Climate & Weather
The climate of the Islands is strongly influenced by the maritime conditions of their location and the prevailing westerly winds.
Winters are mild and summers cool with little temperature variance between them.
August is the warmest month on the Islands, although May gets more hours of sunshine. January is the coolest month, but also provides excellent storm watching and surfing opportunities.
The Queen Charlotte Mountains shield Haida Gwaii's east coast from much of the precipitation and makes the east coast of the Islands considerably drier than the west coast. Annual precipitation of the Islands' east coast is ~52 inches compared with ~168 found along the west coast.
Haida Gwaii, along with coastal BC has a higher mean temperature in the winter months than any other part of Canada. Annual snowfall is less than 30 inches, although winter precipitation is heavy.
Summer to winter temperatures vary little and the temperatures along the coast rarely drops below freezing. Summer temperatures are considered “hot” in the mid-twenties and winter temperatures are considered “cold” at 5 degrees Celsius.
Visitors should be prepared for comfortable temperatures and some rain regardless of the time of year they visit. Precipitation is generally short lived, hence a frequent local comment, "if you don’t like the weather, wait 10 minutes"!
