Heat Records

Kamloops smashes nearly 90-year-old daytime temperature record

Sep 18, 2025 | 6:36 AM

KAMLOOPS — The daily high temperature in Kamloops Wednesday (Sept. 17) broke a record that stood for nearly a century.

According to preliminary numbers from Environment Canada, a temperature of 34.1 C was recorded at Kamloops Airport Wednesday, making it the hottest Sept. 17 on record. It broke the previous record  of 32.2 C  set back in 1937. Records for Kamloops have been kept since 1890.

Other daytime high temperature records for Sept. 17 that fell include Blue River (30.3 C in 2025, 28.0 C in 1981), Clearwater (32.1 C in 2025, 30.0 C in 1967) and Salmon Arm (29.5 C in 2025, 29.4 C in 1937). Cache Creek tied its record of 32.5 C set in 1981.

The weather agency credits the heat to a strong ridge of high pressure that’s bringing unseasonably high temperatures across B.C. in September.

The BC Wildfire Service says the spell of hot weather has led to an increase in the number of active fires in the province, with about 128 burning as of this morning.

The service says seven new fires were started in the last 24 hours versus five declared out, adding that the southern Interior will remain warm today despite cooler conditions in the coastal regions.

“Some moisture is anticipated heading into Friday, but overall the province will remain generally warm and dry,” the BC Wildfire Service said, noting while the summer is behind us, wildfire season is still active in B.C.

“Multiple Area Restrictions remain in effect in the vicinity of active wildfire incidents. Open fire prohibitions are still in effect across many regions, and local bylaws may apply too.”
