How to Prepare
A heat wave is defined as three or more days of temperatures of 32°C or more. Poor air quality can pose additional health concerns when extreme heat combines with air pollutants from industry, gas-powered vehicles, and other sources.
Humidex values measure how hot the weather feels to the average person. Under normal conditions, your body produces sweat that evaporates to cool you down. Under extreme heat, the body must work harder to maintain its normal temperature. A humidex advisory is issued when humidex values are expected to reach 40 or more. The higher the humidex, the harder it is for your body to cool itself.
Smog levels indicate and forecast the current air quality information. Most smog days in Ontario occur between May and September. When an alert is issued, avoid strenuous physical outdoor activities. If you have a heart or lung condition, consult your family doctor on how to keep healthy in the heat.
