Check the live forecast above for today’s conditions in Jasper, then plan around the mountain weather that can shift quickly through the Rockies. Jasper’s elevation and valley position mean cooler summers, snowy winters, and frequent afternoon cloud build‑up from the surrounding peaks.
What’s the weather like in Jasper today?
The live forecast above shows temperature, wind, and precipitation for Jasper. Because the town sits in the Athabasca River valley at 1,060 metres, daytime highs often run a few degrees cooler than in nearby Hinton or Valemount. Afternoon thunderstorms are common in July and August, while winter brings steady snowfall that lingers into April. For a broader look at the region, see the Canada weather hub or check Grande Prairie weather for a plains comparison.
What should I expect for the week ahead?
The live forecast above includes the next several days. For weather in Jasper tomorrow and the outlook for the rest of the week, note that cold fronts from the Pacific stall over the Continental Divide, often producing a few extra centimetres of snow in late spring and early autumn. If you’re looking further out, the weather Jasper 14 days and Jasper weather 21 day forecast can give a general trend, but mountain forecasts become less reliable beyond a week. For a monthly perspective, see Jasper Canada weather by month on the Environment Canada site.
When is the best time to visit Jasper for good weather?
July and August offer the warmest highs near 22°C and the least rain, though afternoon showers are still possible. June and September are cooler but less crowded. Winter (Dec–Feb) is cold but excellent for northern lights and skiing.
Does it snow in Jasper in summer?
Snow in June or August is rare but not impossible at higher elevations. The town itself sees snow only from October to May. Check the live forecast above and local road reports if you’re heading into alpine areas.
How does Jasper’s weather compare to Banff or Lake Louise?
Jasper is slightly cooler than Banff in summer due to higher elevation and latitude, and it receives more snow in winter. Both towns share a similar mountain climate, but Jasper feels more remote. For conditions further west, see BC weather.
