B.C. heat turns up the pressure as readings challenge 2025's high

An early-season heat wave is expected to raise temperatures in southern B.C. to the mid to upper 30s this weekend and early next week.

Get ready to sweat — parts of British Columbia are heading into a hot spell that could challenge Canada's highest temperature of the year so far.

An early June heat wave is building across southern B.C., with some communities expecting daytime highs close to, or even matching, the country's current high of the year, a scorching 37°C set in Winnipeg on May 13.

Osoyoos on record watch

A strong ridge of high pressure is causing hot and dry air to build over the south coast and interior, driving temperatures sharply upward.

All eyes are on Osoyoos, where highs are forecast to hit 36°C on Sunday, 37°C on Monday and 36°C again on Tuesday. 

If those numbers hold, the community may tie or even break the national heat record for 2025.

  • Kamloops: 33°C Sunday

  • Kelowna: Low 30s for all three days

What this means for you

This stretch of extreme heat may be short and quick, but it is expected to bring uncomfortable conditions and an increased wildfire risk, particularly in dry terrain with little to no rain in the forecast.

Keep cool by:

  • Closing blinds during the hottest parts of the day

  • Drink plenty of water

  • Avoiding strenuous activity outdoors

  • Watching for indications of heat-related illness
