Get ready for a taste of mid-summer in Toronto this Thursday as temperatures soar to a high of 28 °C, feeling even hotter with a humidex near 33. This unexpected heatwave marks one of the warmest days of the month, defying the typical mid-September cool-down.
According to Environment Canada, Thursday will be mostly sunny with gentle breezes, creating perfect conditions for outdoor activities. The humidity levels will intensify the heat, making it feel more like the peak of summer rather than the beginning of fall.
Normally, mid-September in Toronto sees daytime highs around 22 °C, but Thursday’s forecast is set to break that trend by being six degrees above average. The humidex will further elevate the perceived temperature, making it more than 10 degrees warmer than the seasonal norm.
While September usually signals a gradual decrease in temperatures, this week’s unseasonable warmth is extending the summer vibes for Torontonians. However, the heatwave won’t stick around for long as a cold front is expected to move in on Friday, ushering in cooler and drier air for the weekend ahead.
As the mercury drops, Saturday’s high is predicted to be a cooler 19 °C, almost 10 degrees lower than Thursday’s peak. The skies will remain clear, promising a refreshing and comfortable start to the weekend.
Overnight temperatures will also decrease, dipping into the low-to-mid teens with a chilly 9 °C expected on Friday night. Sunday may see a slight temperature rebound with a high of 24 °C, mixed with sun and clouds. Evening showers are possible, with a 30 per cent chance of rain, though overnight temperatures will stay relatively mild at 15 °C.
Despite the brief cooldown, forecasts indicate a slight warm-up early next week, with rain expected on Monday and Tuesday. Daytime highs of 25 °C and 24 °C are expected, along with a chance of showers.
