Heat warnings issued by a number of medical officers in the Hamilton-Niagara region are still in effect almost a week after a number of municipalities endured temperatures in the 30s with very high humidex values.

Environment Canada says the “prolonged period” of hot weather is likely to persist through Friday with humidex values close to 40 for at least two of the next three days.

“Daytime high temperatures in excess of 30 C, with humidex values in the high 30s to low 40s, are expected,” the weather agency said in its statement on Wednesday morning. “Overnight lows near 20 C are also expected through this period, providing little relief from the heat.”

Thursday is expected to be hotter with sunshine, 34 C and a humidex value reaching 41.

Friday will be sunny again with a high of 33 C.

As intense as the current heatwave is, Environment Canada says no records are expected to be broken. The agency says the period of July 6-10 in 1988 produced temperatures between 34 C and 37 C in the region.

The heat warning issued last Thursday from Hamilton’s medical officer of health is still in effect. As a result, the city’s “cool places” are operational during the heat event despite the COVID-19 pandemic, and locations can be identified by a “Cool Down Here” sign at the entrance.

Free drinking water will be available at the following sites during the heatwave:

  • Spray pads at Waterdown Memorial Park, Dundas Driving Park, Village Green, Pier 4 Park, Gage Park, Winona Park and the Binbrook Fairground Community Park (open 9 a.m. to 9 p.m.)
  • Beaches at Bayfront Park, Beach Boulevard, Binbrook Conservation Area, Christie Conservation Area, Confederation Beach Park, Pier 4 Park Beach, Valens Conservation Area Beach and Van Wagner’s Beach
