‘This heat is extreme’: Warning extended as London temperatures soar

A heat warning is in effect across the region. CTV London’s Reta Ismail has the details on what you need to know to stay safe and cool.

With scorching temperatures and high humidity gripping the region, public health officials are urging residents to take the season’s first heat warning seriously.

“This isn’t just the first heat event of the season — it’s also an extended one,” said Dave Pavletic, environmental health manager with the Middlesex-London Health Unit. “That increases risk due to the cumulative impact of extreme heat, especially for seniors, children and people with chronic health issues.”

In response, the City of London has activated its extreme temperature response plan. Four community centres are now operating as cooling centres, offering relief to anyone in need of a break from the heat.

Officials are also urging residents to check in on neighbours, family members and friends, particularly those living alone. Even short exposure to extreme temperatures can be dangerous.

“It’s extremely hot, and it’s been sustained for a few days,” said Dr. Rodrick Lim, medical director of paediatrics at London Health Sciences Centre. “We’re seeing concerns around heat exhaustion, especially in kids and vulnerable populations who may not be able to express how they’re feeling.”

Spray pads across the city remain open, offering a way for families to cool off. But health experts continue to advise the public to stay hydrated, and limit time outdoors during peak afternoon hours.

On a sun-drenched tennis court in London, coach Bill Kovach is still training athlete Kael Paolo but with added precautions.

“They’re well supplied with electrolyte water, and it’s not new for them to spend time [in the heat],” said Kovach. “Now, yeah, today is a little more extreme than normal, but we have breaks.”

Paolo is training for a big tournament in Hamilton this weekend, and as an athlete, he’s conditioned to spend time in the heat.

The heat warning has been extended through mid-week, as forecast highs hover around 31 degrees with humidex values near 40. Overnight lows are also expected to remain above 20 degrees offering little relief.

As a result, all city sports fields are temporarily closed, and local schools have cancelled outdoor field trips for the next several days.
