Excessive Heat and Humidity Expected in the Sault for Several Days

Environment Canada and U.S. Weather Service are forecasting some very hot and humid conditions starting Monday and lasting through most of next week. Along with the heat and humidity comes chances of rain showers and thunderstorms.

Elevated heat and humidity is expected for several days beginning on Monday. Daytime highs on Monday through Wednesday are expected to be 28 to 33 degrees Celsius with humidex values of 36 to 42.

There will be little relief through the overnight as lows are expected to be 18 to 22 degrees Celsius with humidex values of 25 to 30. Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category.

Extreme heat can affect everyone’s health. The health risks are greater for older adults, infants and young children, pregnant people, people with physical and/or mental illnesses, and people with disabilities or mobility issues. Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.

Drink plenty of water regularly, even before you feel thirsty to decrease your risk of dehydration. Thirst is not a good indicator of dehydration. Watch for early signs of heat illness (feeling unwell, fatigue, thirst, headache) as these can rapidly evolve into life-threatening emergencies. Move to a cooler environment immediately, such as a shaded or air-conditioned space.

Animals also suffer with excessive heat and humidity. It is recommended to walk your dog in the early morning hours or later at night. Make sure any animal outside has shaded and fresh water and NEVER leave a dog in a hot car even with the windows open.
