An early-June heat event 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, Man., on May 13.

Eyes on Osoyoos and Castlegar
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 and Castlegar, B.C., where highs are forecast to hit 37°C on Monday.

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

What this means for you

Special weather statements remain in effect across parts of the province.
Residents are encouraged to use caution in the heat, especially those with special needs such as children, the elderly and those without access to cool shelter.
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
