Toronto is set to enjoy an unusual burst of warm fall weather, with temperatures soaring above the typical October norms.
The upcoming weekend is expected to be exceptionally sunny and warm in Toronto, with Friday reaching a high of 25 °C and both Saturday and Sunday hitting a balmy 27 °C. Even Monday is forecasted to maintain the warmth at 27 °C before a sudden drop in temperature later in the week.
For reference, the usual daytime high in Toronto for October is around 16 °C, with nighttime lows dipping to about 8 °C. It’s rare for daily highs to exceed 20 °C, making this weekend’s forecast of 10 to 11 degrees above the norm quite remarkable.
Comparatively, past warm October spells in the city have seen highs of 24 °C in 2020 and 23 °C in 2021. This weekend’s stretch of three consecutive days above 25 °C puts it in the ranks of the warmest early-October periods on record.
Although Monday will maintain the heat at 27 °C, a shift is expected by Tuesday with rain and temperatures dropping to 22 °C, signaling a return to more typical fall weather patterns.
By midweek, daytime highs are anticipated to moderate into the mid-teens, aligning more closely with historical averages for this time of year.
On average, October in Toronto sees about 11 days of rain and approximately 91 mm of precipitation, according to long-term climate data.
