A sweltering heat wave pushed temperatures to record-breaking highs across several southern British Columbia communities on Tuesday, June 10, 2025, according to Environment and Climate Change Canada (ECCC).
Cranbrook was among the cities setting new daily maximum temperature records.
The area reached 33.6°C, beating the previous high of 30.2°C set in 2015.
Historical weather data for Cranbrook dates back to 1901.
The extreme heat affected many communities in the southern Interior, with new records also set in the following areas:
-
Castlegar Area: 34.8°C, surpassing the old record of 32.9°C from 2015 (records since 1916)
-
Nelson Area: 34.8°C, topping the 32.9°C set in 2015 (records since 1904)
-
Sparwood Area: 30.2°C, breaking the 27.3°C record from 2015 (records since 1969)
-
Trail Area: 35.6°C, exceeding the previous record of 33.6°C from 2015 (records since 1928)
ECCC noted that many of the previous records were set just a decade ago in 2015.
The recent spike in temperatures is creating concerns about the frequency and intensity of heat waves in the province.
Environment Canada continues to monitor the situation and may issue further heat warnings as conditions develop.
