Geographical influences

Whistler’s location near the Pacific Coast, in south west Canada by the Coast Mountains, produces a climate less extreme than the country’s inland mountain towns. The mild ocean air stops temperatures falling too low in late summer. It’s not as humid and there’s no thunderstorms like in Edmonton and Toronto.


Thanks to its temperate climate, the weather in Whistler in September sees good daytime temperatures and lots of sunshine. The average daytime high’s around 19°C, dropping to 12°C on rare cooler days. The sun will shine for an average of nine hours this month from 13 hours of daylight. The rain’s not too heavy in Whistler in September. About 80mm falls on average with ten rain-affected days. The UV level’s moderate and the humidity will measure around 74%, but use sunblock and carry water when you’re exploring the resort in the sun. The average wind speed is very light at 4mph.
