Lytton, B.C., records hottest temperature across Canada this year as province bakes

Lytton, B.C., Records Highest Temperature in Canada as Heat Wave Continues

Lytton, B.C., is maintaining its reputation as Canada’s hot spot, with the highest temperature recorded across the country so far this year as a relentless heat wave grips much of the province.

According to Environment Canada data, Lytton reached a scorching 41.3 C on Monday, making it the hottest temperature of 2025 in Canada.

The town also broke a daily maximum temperature record for Aug. 25, surpassing the previous record set back in 1934 with a temperature of 37.2 C.

Along with Lytton, 16 other areas in B.C. set new daily maximum temperature records on the same day, including Whistler, Pemberton, Kamloops, Kelowna, and Burns Lake.

Cache Creek saw a high of 38.8 C, breaking the previous record of 37.1 set in 2022, while Lillooet reached 38.5 C, surpassing the previous record of 37.3 from the same year.

Heat Warnings and Forecasts

Environment Canada has issued heat warnings for several regions, including the Fraser Canyon and southern parts of the Thompson and Okanagan areas, where daily highs of 35 to 39 C are expected until the end of the week.

Matt Loney, a meteorologist with Environment Canada, predicts that the heat will ease on Friday as cooler marine air moves in from the coast and spreads into the Interior. However, the first week of September is anticipated to be warmer than usual.

Additional heat warnings are in place for inland sections of the north and central coasts, while a heat-related special weather statement covers much of Vancouver Island.

Wildfire Concerns

Despite the declining temperatures as fall approaches, the number of wildfires in B.C. remains steady at around 70. The BC Wildfire Service has warned that the hot and dry conditions increase the risk of wildfires.

Currently, seven fires are classified as burning out of control, including the Sailor Bar fire in the Fraser Canyon, which has been mapped at 111 hectares.

Evacuation alerts for the Yale and Spuzzum areas are still in place due to the fire, and crews are working with CN Rail to access areas at the top of the blaze.

Outlook for September

Loney explains that while temperatures are generally decreasing as fall approaches, there is still the potential for late-season heatwaves, as seen with Lytton hitting 41 C as late as Aug. 30 in previous years.

Looking ahead, the forecast for September becomes less clear, with the possibility of warmer temperatures and less rain than usual.

Overall, the heat wave in B.C. continues to pose challenges, with the province bracing for ongoing high temperatures and wildfire risks.
