Jasper weather at a glance
The figures on this page are climate normals for 1991 to 2020 from the Environment and Climate Change Canada station at Jasper. They show what a typical month looks like in the town. They are not a forecast for any particular week.
Mountain areas are colder than the town. The Columbia Icefield and higher viewpoints do not follow the town numbers, so pack for a bigger range than the table shows.
