Whistler weather in the Coastal Mountain Range is moderate throughout the year. The trees are kept green with Spring showers and the abundant sunlight keeps our flowers blooming all summer long. Whistler Ski conditions are reliable and consistent with an average annual snow fall of just over 39 feet. The summer’s are hot and lazy and the winter’s are just cold enough for tons of great snow. Come for a Whistler Bike Vacation in summer or a Whistler Ski Vacation in winter!
