Climate Chart of Jasper National Park, Canada

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures are coolest in December, at -11.3 °C, and warmest in July, at 16.5 °C. These are averages for the whole month, not daytime highs or lows, so they should be treated as a seasonal planning guide rather than a forecast of daily conditions. The unweighted mean across monthly means is 2.5 °C; it is not a day-weighted annual average.

Snow

Mean daily snowfall is highest in November at 12.34 mm/day, and lowest in August at 0.08 mm/day. The unweighted mean across monthly daily averages is 6.49 mm/day. These amounts do not establish how many days receive snow, snow depth or snow cover, so they cannot by themselves indicate conditions for skiing or other snow-dependent activities.

Rain

Mean daily rainfall reaches its highest monthly average in July at 2.98 mm/day, and its lowest in December at 0.01 mm/day. These are daily mean amounts, not monthly totals, and they do not tell you how often rain falls or whether a particular day will be wet. The unweighted mean of the monthly daily averages is 1.03 mm/day, useful as broad context rather than a day-by-day expectation.

Sunshine

Mean daily sunshine duration is highest in July at 12.78 hours/day and lowest in December at 4.17 hours/day. The unweighted mean across the monthly averages is 8.53 hours/day. These figures describe average sunshine duration, not day length or a guarantee of clear skies on an individual day.

Best Travel Time Guide for Jasper National Park, Canada: Ideal Seasons and Weather Insights

For visitors prioritising cooler monthly average temperatures, December is the relevant option, with a monthly mean of -11.3 °C; this does not mean every day will be equally cold, so check forecasts and prepare for changing daily conditions. For a lower average rainfall criterion, December has the lowest mean daily rainfall at 0.01 mm/day. That average does not guarantee dry days or indicate how frequently rain occurs, so rain-ready clothing remains a practical choice. For outdoor plans guided by average sunshine duration, July records 12.78 hours/day per day, while December records 4.17 hours/day; sunshine duration is not the same as daylight length, nor a promise of clear weather. Rain preparation is especially relevant in July, when mean daily rainfall is 2.98 mm/day. These criteria point to different planning considerations rather than one universally best time to visit, and the averages cannot replace a local forecast. Snowfall averages may also matter when planning activities: mean daily snowfall is highest in November at 12.34 mm/day. This does not show the number of snowy days, snow depth or cover, so check current conditions if your plans depend on snow.
