Environment Canada has put Burlington, Brant County, Hamilton, Haldimand County, Norfolk County and Niagara region under a heat warning for the next two days.
Heat warnings are issued when weather conditions are expected to pose a higher risk of heat illnesses, such as heat stroke or heat exhaustion.
The national weather authority states daytime temperatures are expected to reach the mid thirties on Tuesday and Wednesday.
“Temperatures Tuesday night and Wednesday night in the low twenties will provide little relief from the heat,” read the alert.
Environment Canada said conditions will improve by Thursday.
The agency offered some tips for those two days.
“People and pets shouldn’t be left in cars. Never leave people or pets inside a parked vehicle. When it’s hot eat cool, light meals,” read the alert.
During heat warnings, Hamilton opens up sites where people can cool down amid the heat warning. Open swims at the city’s indoor pools are also open to people, free of charge.
This comes after a heat warning last week that had the city feeling like 40 C.
