Weather in Jasper in July
Canada · 20-year averages, July
A good month. July is a solid month to be in Jasper. You should expect rain on 18 days of the month, which is more days wet than dry.
July ranks 2 of 12 in Jasper. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain on 18 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest July day reached 32.4 °C and the coldest night fell to 1.8 °C, and the wettest single day dropped 38 mm — roughly 38% of the month's rain in one day.
July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 169 mm against 45 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 99 mm average is a reasonable planning figure, not a promise.
Wind is light at 0.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.
How July sits in the year
Temperatures hold steady either side: 18.2 °C in June, 21.5 here, 20.8 in August. Nothing about the timing within the month matters much.
Daylight in July
July is at or near the longest days of Jasper's year: 16.5 hours of daylight, losing 1.1 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.
An inland climate
With no coast nearby, the year swings a fair way — 33.4 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. At 1062 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
July in Jasper versus nearby
If Jasper is one option among several, the nearby comparison is worth making. Banff is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Edmonton is close enough to be a coin toss — 2 °C warmer, 3 days less rain.
So: July is effectively as good as it gets here — 6 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
