What is the weather in Toronto today?
Toronto’s weather today is shaped by the same system shown in the live forecast above. Expect a mix of sun and cloud with temperatures near the seasonal average for this time of year. Lake Ontario can bring sudden breezes or lake-effect clouds, so the live reading is more accurate than a general prediction.
How should I dress for Toronto weather today?
Layer up if the live forecast shows a wide temperature swing between morning and afternoon. A light jacket or sweater works for most spring and autumn days, while a waterproof shell is smart if rain is in the forecast. In winter, add a warm coat, hat and gloves when the mercury drops below freezing.
Does Toronto get lake-effect snow?
Yes. Cold air passing over the relatively warm waters of Lake Ontario can produce narrow bands of heavy snow, especially in areas north and east of the city. This can make local conditions very different from the rest of southern Ontario.
Is Toronto’s weather usually humid?
Summers in Toronto can feel humid due to moisture from Lake Ontario and the Great Lakes basin. Humidex values often climb above 30°C on hot July and August days, making it feel warmer than the actual air temperature.
How often does Toronto get thunderstorms?
Thunderstorms occur most often in late spring and summer, typically in the afternoon or evening. They are usually brief but can bring heavy rain, gusty winds and lightning. Check the live forecast above for any severe weather alerts.
