Dawson City residents with gardens should keep an eye on the thermometer Wednesday night, as Environment Canada is calling for a low of -1°C, bringing a risk of frost to the Yukon community.
The forecast for Wednesday, September 2, 2026 calls for a cloudy day with a 40 percent chance of showers and a high of 13°C, but skies are expected to clear overnight, dropping temperatures below freezing.
According to Environment Canada, today’s weather is mostly cloudy with a high of 13°C and a 40 percent chance of showers tonight, with a low of 5°C. The rest of the week will see daytime highs between 13°C and 16°C, close to the seasonal normal of 16°C for this time of year.
The frost risk is particularly important for local gardeners and farmers. Dawson City averages only 70 frost-free days per year, one of the shortest growing seasons in Canada. According to the Yukon Agricultural Association, killing frosts can occur any month of the year in the territory, and the growing season officially ends when temperatures drop to -2.2°C after July 15.
The area is home to about 20 farms, and the Dawson City region typically enjoys a slightly warmer climate than Whitehorse, giving it a longer growing window. Still, a frost this early in September can damage tender plants and crops, so residents may want to cover sensitive vegetation or bring potted plants indoors Wednesday night.
Beyond Wednesday’s frost risk, the week looks mild for late summer, with only a few chances of showers and near-normal temperatures, providing good conditions for outdoor activities in Dawson City.
