Dawson City, Yukon, is in for a hot and sunny start to the week, though the warmth won’t last long. Environment Canada is forecasting a high of 28°C on Monday, July 20, 2026, with a humidex of 29, making it feel even warmer. That’s about five degrees above the seasonal normal of 23°C for this time of year.
The day is expected to be sunny before a mix of sun and cloud moves in this afternoon. Winds will pick up from the southeast at 20 km/h, gusting to 40 km/h near noon. The UV index is forecast to be 5, or moderate, so residents and visitors heading outdoors should still take sun precautions.
Early morning observations from Dawson Airport showed partly cloudy skies and a temperature of 14.2°C, with light northeast winds and 62 percent humidity. Conditions are expected to warm quickly through the morning.
The heat will be short-lived. Tuesday’s high drops to 21°C with a 30 percent chance of showers, and temperatures will continue to slide through the week. Wednesday is expected to reach 20°C, Thursday 18°C with periods of rain, and Friday just 14°C with showers.
The warm Monday fits a broader pattern for the territory this summer. Environment Canada’s seasonal outlook predicts Yukon is among the regions most likely to see above-normal temperatures between June and August, partly due to a developing El Niño pattern.
Dawson City’s subarctic climate usually brings an average July temperature of 15.7°C and normal daytime highs around 23°C. The all-time record high for the community is 35.0°C, reached on July 9, 1899, and tied on June 18, 1950.
Residents can expect ideal outdoor conditions early in the week before unsettled weather settles in. Those planning activities later in the week should prepare for rain and much cooler temperatures.
