Traveller notes on Jasper in August
Other months in Jasper
Jasper's forum calls September genuinely changeable — regulars describe days warm enough for shorts followed by others that bring an early snow flurry, so layers and a warm fleece are standard advice. Nights routinely dip into the single digits even when the days stay mild, and it's still one of the park's busier months before the crowds thin out.
