Jasper National Park Weather

While Jasper National Park weather varies greatly, there are two influxes of visitors—one in the warmer months and the other in winter. SUMMER (late June to mid-Sept.) is definitely high season, especially the school holiday period of July through August. Simply said, the weather is unbeatable. The season is dominated by long, warm—and sometimes hot—days, everything is open, and there’s plenty to do and see. Crowds, high prices, and difficulty securing reservations are the downside of summer travel.

Late spring and early fall are excellent times to visit Jasper National Park for two reasons: you’ll avoid the crowds, and you’ll save money. SPRING (mid-Apr. to late June) is notable for long days of sunlight (in late June it stays light until after 10 p.m.) and a sense of optimism for the upcoming warm months.

FALL (mid-Sept. to Nov.) can be delightful, especially September, with lingering warm temperatures and a noticeable decrease in crowds immediately after the long weekend (at the beginning of the month). While fall colours in general lack the intensity of those in the eastern provinces and New England, larch turns a brilliant yellow throughout high alpine areas in late September.

Marmot Basin Ski Resort opens for the WINTER season (Dec. to mid-Apr.) in early December. The better snow conditions are often January to February, although for enthusiasts looking for a combination of good snow and warmer weather, March is an excellent time of year to visit.
