First heat wave of 'torrid summer' to hit Eastern Canada next week
The first heat wave of Summer 2025 is about to hit Eastern Canada, with temperatures climbing to the mid-30s early next week. Add the humidity from a wet spring and it will feel even hotter. Article content We'd better get used to it, as it is signalling 'a torrid summer ahead,' says David Phillips, senior climatologist with Environment and Climate Change Canada. Article content 'We rarely go a year without a heat wave,' he says, 'but this will be the first one and people have to learn how to deal with it again.' Article content Article content The high pressure system will settle over southern and eastern Ontario as well as southern Quebec. It will edge into southeastern Manitoba on one side and western New Brunswick on the other. Article content Article content Contrasting this spate of heat with the renown 'polar vortex' of winter, Phillips refers to this phenomenon as a 'Bermuda High.' That's a semi-permanent, subtropical area of high pressure, which usually migrates east-west, back and forth across the North Atlantic, influencing weather patterns. Except this one is further west and further north than usual, says Phillips. Article content 'It circulates southern air further north.' Article content There's no doubt it will feel oppressive, says Phillips, adding that a heat dome squeezes air molecules, pressing them downward, creating heat from the friction. Article content How will a lot of spring rain play a role? Article content Moisture from a particularly wet spring will compound with the heat. There has been 30 to 40 per cent more precipitation than normal this year, he says. Article content Article content During the day the humidity may make it feel like 40 degrees Celsius or more. Article content Article content Another factor in the mix is the sunshine. Long summer days 'prevent the cool-off,' he says. At night, it will feel tropical, with temperatures above 20 C. Article content Normally, Eastern Canada would have several days in the 30s by now, says Phillips, but there were none in May and only one in June. Contrast that with Winnipeg, which he says has had nine or 10. Article content But now summer heat is arriving with a vengeance. It will be a three-day event with temperatures rising to the mid-30s in Toronto, Ottawa and Montreal, accompanied by nighttime temperatures in the 21-23 C range, with the humidex in the low to mid 40s. 'That's eight or nine degrees warmer than normal.'

Summer heat wave set to hit Ontario may bring temperatures not seen in years
Southern Ontario is set to get hit with a strong heat wave just in time for the official start of summer. Global News meteorologist Anthony Farnell says a large heat ridge or dome will build over the Ohio Valley in the U.S. and expand into southeastern Canada by the end of the weekend. With the summer solstice, which occurs on Friday and is the longest day of the year for hours of sunlight, residents in southern Ontario will finally start to feel the true heat after a back-and-forth spring season. Temperatures are expected to soar into the low to mid 30s for at least three days in southern Ontario and two or more days in Quebec, Farnell said. The hottest day will be on Monday, when the high is forecasted to hit above 35 C in Toronto, and the humidex could briefly reach as high as 45 C. Story continues below advertisement 'This would be a record for the date and the hottest temperatures we've experienced in three years,' Farnell said.

He also said there is a risk of some 'very strong thunderstorms along the warm front as the heat and humidity sweeps in this weekend.' 'Computer models have not been able to show exactly where these storms will form or when but be on the lookout late Saturday into Sunday morning, especially across cottage country and eastern Ontario for quite the light show,' Farnell said. Story continues below advertisement However, Farnell did note that temperatures will still remain above seasonal up until Canada Day. 'The first heat wave of the year is always more dangerous because our bodies haven't yet adapted,' Farnell said. According to Environment Canada, Toronto is expected to see a high of 25 C on Friday for summer solstice, 28 C on Saturday, and temperatures will soar into the 30s for Sunday, Monday and Tuesday.
