Sweater weather may loom just around the corner for Ontario, but a new three-month outlook from Environment and Climate Change Canada (ECCC) is providing some hope that patio season could extend deep into the fall months. ECCC's latest temperature probabilist forecast bodes well for anyone trying to stretch the most out of their summer in Ontario. That figure jumps to a 50 per cent chance for Ontario's northern hinterland, and increases even more to 60 per cent for the northernmost reaches of the province. The government climate agency also notes a 10 per cent chance of below-normal temps across much of the province, with that number jumping to 20 per cent in southwestern Ontario. The forecast echoes the Farmers' Almanac Extended Fall Forecast for 2025, released this July.
