A heat warning is in effect for Peel and Halton Regions, Environment Canada announced Tuesday.
Temperatures are nearing 31 C Wednesday and Thursday, while overnight lows hover around 20 C, meaning there’s little relief for those looking to cool off.
The Region of Peel’s Medical Officer of Health is also issuing a heat warning.
“Although an increase in the number of hot days is dangerous, it is the combination of heat during the daytime and nighttime that causes significant increases in heat-related morbidity and mortality. This is because there is no break from the heat which is important for allowing the body to cool off.”
The Region’s top doctor is advising residents avoid being outdoors between 11 a.m. and 4 p.m., when UV radiation is strong.
