Environment Canada has issued Hamilton's sixth heat warning of the summer, with temperatures expected to reach 33 C by Sunday. There were four, all of last year.

According to Environment Canada meteorologist Crawford Luke, the city is experiencing significantly warmer conditions this season — July averaged 22.4°C, compared to the historical average of 20.9°C, and June came in at 19.7°C, about 1.2 degrees higher than normal.

"There's still a lot of summer left," said Luke, adding that Hamilton could see another one or two heat warnings before the season ends.

The multi-day heat event begins Saturday, with daytime highs above 30 C and overnight lows near 23 C, offering little relief from the heat. The humidex values are expected to range between 35 and 40, according to Environment Canada.
