April 5th in Jasper typically lands in that in-between zone of spring — expect a high around 60° and a low near 38°. The date's range tells the real story though: it's hit as warm as 81° as recently as 2023, and dropped to a frigid 20° back in 2018. There's roughly a 1-in-3 chance of rain, but snow is essentially off the table.
Jasper's weather has real teeth on both ends — the all-time high of 109° in July 2012 and an all-time low of -25° in January 1994 represent a brutal 134-degree swing. Single-day rainfall peaked at 5.67 inches on July 23, 2017, and the town once picked up 13 inches of snow in a single December day back in 2004.
Summers are legitimately hot here, with mid-July averaging highs of 87° and the full summer stretch staying in the mid-to-upper 80s from June through August. Winters are cold but not punishing — January and February hover in the low-to-mid 40s for highs. If you're trying to dodge the rain, avoid late April through early May, which is Jasper's wettest stretch of the year.
