Lytton, BC Hits 40C (104F) Then Breaks That September Temp Record The Next Day At 40.8C (105.4F)

A spate of extremely hot weather in British Columbia has broken Canada’s national maximum temperature record for September.

On Tuesday, it reached 40C (104F) in Lytton, matching the previous all-time high. This is only the third time that temperature has been recorded in the country in September.

The mercury rose again the following day, climbing to 40.8C in nearby Ashcroft, which breached the record set the day before. This follows an intensely hot and dry summer across Canada, which has fuelled an extreme fire season – its second worst on record. The country experienced its worst wildfire season on record in 2023, when more than 17m hectares (42m) hectares burned.

Smoke from such wildfires have travelled over the Atlantic this summer, bringing hazy skies to swaths of Britain. Extreme heat and damaging wildfire seasons are expected to continue as the climate crisis alters weather patterns around the world.
