Thirteen communities across British Columbia shattered longstanding daily high temperature records on June 23, 2026, as a persistent ridge of high pressure brought unseasonably warm conditions to the province. Environment Canada confirmed the milestone, with several locations surpassing records that had stood for decades.
Record-Breaking Temperatures Across B.C.
The most notable new record was set in the city of Kamloops, where the mercury hit 38.2°C, eclipsing the previous June 23 record of 36.1°C set in 1995. Other communities, including Kelowna, Vernon, and Penticton in the Okanagan Valley, also saw temperatures climb past 35°C, breaking records by margins of up to 2 degrees.
In the Lower Mainland, Abbotsford reached 33.4°C, surpassing the old mark of 31.7°C from 2006. Vancouver International Airport recorded 29.8°C, falling just short of its record but still well above seasonal norms. Coastal areas like Victoria and Nanaimo also set new highs, with temperatures in the low 30s Celsius.
Heatwave Impacts and Public Health Warnings
The extreme heat prompted Environment Canada to issue heat warnings for much of the province, urging residents to take precautions against heat-related illness. Officials advised staying hydrated, avoiding strenuous outdoor activity during peak afternoon hours, and checking on vulnerable individuals, including the elderly and those without air conditioning.
Emergency services reported a spike in calls related to heat exhaustion, particularly among outdoor workers and homeless populations. Cooling centers were opened in several cities, including Vancouver, Surrey, and Kelowna, offering respite from the heat.
Climate Context and Future Projections
Meteorologists noted that the record-breaking temperatures are consistent with long-term warming trends linked to climate change. According to David Phillips, a senior climatologist with Environment Canada, events like this are becoming more frequent and intense. “What was once a once-in-a-century event is now happening every few decades,” Phillips said in an interview. “We’re seeing more days above 30°C, especially in regions that are traditionally cooler.”
The heatwave is expected to persist through the weekend, with temperatures remaining 10 to 15 degrees above seasonal averages. Cooler weather is forecast to arrive early next week as a Pacific front moves inland.
