Sunny weather initiates under the heat advisory
Canada Experiences Prolonged Heat Wave
Canada is currently in the grip of a significant heat wave, with temperatures consistently in the low to mid-30s Celsius and humidex values pushing discomfort levels higher. The heat event, which began on Saturday and is expected to last until the middle of next week, is particularly affecting Eastern and Atlantic provinces, where Environment Canada has issued heat warnings.
Temperature and Humidex
Many regions, including Toronto, Montreal, and Halifax, have already experienced multiple days above 30°C this summer, surpassing normal counts. Recent heat records include Miramichi at 37.6°C and other Atlantic regions with temperatures in the mid-30s Celsius, with humidex values making it feel even hotter. A cold front expected midweek will likely lower temperatures in parts like Vancouver to around 23°C, signaling temperature relief ahead.
Humidity (Humidex)
Humidex values can be several degrees above the actual air temperature, such as around 32 when air temperature is about 29°C, intensifying the perceived heat and discomfort.
UV Index
During heat waves and summer months, UV indexes in Canada are typically high to very high, increasing risks of skin damage and sunburn. However, precise UV index forecasts for the upcoming week were not available at the time of this report.
Symptoms of Heat Exhaustion
Environment Canada advises limiting outdoor exposure and monitoring for heat exhaustion symptoms, which include heavy sweating, weakness or fatigue, dizziness or fainting, nausea or vomiting, headache, muscle cramps, and dark urine. Heat exhaustion can worsen without proper hydration and cooling, possibly progressing to heat stroke, a medical emergency.
Additional Notes
Drought is widespread, with 71% of Canada classified as abnormally dry or under moderate to extreme drought, which contributes to heat intensity and fire risk. Increased vigilance and protective measures are advised during these prolonged heat events.

Stay safe and hydrated during these hot days, and remember to watch for signs of heat exhaustion. Cooling and hydration are essential.
The current heat wave in Canada, exacerbated by high temperatures and humidex values, is raising concerns about climate-change threats. As environmental scientists study the impacts of this prolonged heat event, it's essential to remain vigilant about symptoms of heat exhaustion and prioritize staying hydrated.
