Minimum Temperature of +25,5°C in Ontario, Canada, Unbelievable +24,8°C in Toronto (!)

Canada is experiencing an exceptionally warm and humid night in Ontario, with minimum temperatures climbing as high as 25.5°C (78°F), shattering numerous June high minimum temperature records across the region. This oppressive heatwave is causing considerable discomfort and raising concerns as even hotter nights loom.

🌙 Record-breaking minimum temperatures

• The Toronto Pearson Airport recorded a June high minimum temperature close to its all-time highest minimum for any month, +24,8°C.
• Many other locations throughout Ontario experienced similarly extreme nighttime lows, setting or approaching new historic records for June.
• These warm, suffocating nights offer little relief after scorching days, compounding heat stress for residents.

🌡️ The heat continues to build

Meteorologists warn that the next several nights could be even hotter, with sustained high humidity making the air feel heavy and uncomfortable. Such conditions increase the risk of heat-related illnesses, especially for vulnerable populations such as the elderly, young children, and those with preexisting health issues.

🌍 Broader impacts and outlook

This historic warm night event fits into a larger pattern of increasingly frequent heatwaves across Canada and much of the northern hemisphere. As climate change drives more extreme temperature swings, urban areas like Toronto face mounting challenges in adapting to these conditions, from power grid stress to public health emergencies.
