The City of Hamilton has announced an “extended heat warning” that will continue until at least Friday.
The heat could last until Saturday as well, the city said in a news release Wednesday morning. The heat warning was also issued by Environment Canada.
“Dangerously hot and humid conditions are expected,” Environment Canada said. “There will be little relief through overnight.”
During the day, temperatures are expected to reach 30 to 35 C with humidex values of 40 to 45 C. Overnight lows are expected to be 20 to 23 C with humidex values of 25 to 30 C.
“Temperatures and humidex values may be several degrees cooler near the shores of the Great Lakes,” Environment Canada said.
The city is offering residents with “cool places” while the warning is in place. Keep an eye out for a “Cool Down Here” sign at the entrance.
The city said open swims regularly scheduled at its indoor pools will be free of charge.
“Signs of heat exhaustion include heavy sweating, weakness, cold, pale and clammy skin, weak pulse, fainting and vomiting,” the city said. “If experiencing symptoms, seek help right away – call 911 if needed.”
Residents can reduce their risk of a heat-related illness by drinking lots of water, staying in an air-conditioned place, wearing a hat or taking an umbrella when out in the sun, wearing loose fitting, light-coloured clothing and wearing sunscreen, the city said.
Residents are asked to check on neighbours and family and reminded to never leave children or pets alone in closed vehicles, said the city.
“Temperatures in a car can become life threatening within minutes.”
