Heat Warning Issued

Heat warning issued for Kamloops-area as temperatures soar above seasonal levels

Aug 24, 2025 | 4:26 PM

KAMLOOPS — Environment Canada has issued a heat warning for the Kamloops area as temperatures have finally crossed the warning threshold during this ongoing spell of warmer weather.

This is the third heat warning of the summer in Kamloops and its expected to last from Monday (Aug. 25) until the latter half of the week. It applies to the South Thompson and the Fraser Canyon.

“We’re still under the same ridge of high pressure that we’ve been under since Thursday,” Environment Canada meteorologist Jennifer Kowal said, noting cooler temperatures are currently expected to return next weekend.

“The shift hasn’t been dramatic as far as the temperatures getting a bit warmer, its just that the new models are showing being ever so slightly in some areas, and that is what triggered us to issue this heat alert.”

In Kamloops, Environment Canada is currently forecasting a day time high of 36 C Monday and Thursday (Aug. 25 and 28) and 37 C Tuesday and Wednesday (Aug. 26 and 27), with Friday’s high expected to be around 29 C.

Overnight lows are expected to be around 17 C tonight as well as on Thursday and Friday, and 18 C Monday through Wednesday.

“Areas west of Kamloops like Ashcroft and Cache Creek could be a good two of three degrees warmer than Kamloops,” Kowal said. “So they’re going to be expecting something closer to 37 C or 38 C.”

In the Kamloops-area, a heat warning is issued when there are at least two consecutive days with a daytime high of at least 35 C and a nighttime low of at least 18 C in between.

“Temperatures are very high and there is a moderate risk to public health,” the weather alert issued at 4:00 p.m. Sunday said.

“Heat affects everyone, but the risks are greater for seniors, people who live alone, people with pre-existing health conditions such as diabetes, heart disease or respiratory disease, people with mental illness such as schizophrenia, depression or anxiety, people with substance use disorders, people with limited mobility.”

Kowal told CFJC that its possible that some daily temperature records will be broken during this heat wave.

“There is the potential but we’re not approaching our all time records from June 2021” she said. “This is not one of those events.”

While the drought rating in the North and South Thompson River basin has dropped to level 0, the BC River Forecast Centre says prolonged warm and dry conditions may cause the situation to worsen once again.

The BC Wildfire Service is also urging caution as it notes this prolonged heat wave across much of the province will increase fire danger in the coming days. There are 70 wildfires burning across B.C., including the Sailor Bar fire near Yale.
