Get ready to embrace the true essence of autumn as Toronto braces for its first real taste of fall chill this Wednesday night. The temperature is expected to plummet to 3°C under clear skies, possibly bringing patchy frost to some parts of the city and its surrounding areas.
This sudden shift in weather comes after Toronto saw a significant change earlier this week. Tuesday brought the city its first substantial rainfall in weeks, accompanied by showers and thunderstorms that ended a period of mild, dry weather. This rain ushered in a cooler air mass, heralding the arrival of crisp nights and pleasantly cool daytime temperatures.
Looking ahead, the forecast promises abundant sunshine for the rest of the week, with daytime highs ranging from 14°C to 18°C, perfectly aligning with what we’d expect for early October.
Tomorrow, anticipate a daytime high of 15°C with clear skies, followed by a chilly low of 3°C overnight, possibly leading to frost. Thursday will see a high of 14°C, sunny skies, and an overnight low around 6°C.
As we head towards the weekend in Toronto, temperatures will gradually climb to 18°C and 19°C, maintaining clear conditions overall. The only anticipated deviation is a possibility of cloudier skies on Sunday, Oct. 12.
Historically, Toronto typically experiences average highs of 15–16°C in the second week of October, with lows around 7°C. This week’s forecast closely mirrors those averages, although the anticipated overnight low of 3°C is among the coldest readings this fall.
This fall weather pattern resembles what Torontonians saw back in October 2024: a rainy start to the month followed by clear, cool days leading up to Thanksgiving. With no rain in the forecast for the long weekend, residents can look forward to perfect conditions for outdoor activities, fall hikes, and Thanksgiving gatherings.
