Check the live forecast above to see if you need an umbrella or a lighter coat today, as Toronto’s weather shifts frequently due to its position near Lake Ontario. The lake moderates temperatures in spring and fall but can also trigger sudden cloudbursts and lake-effect snow in winter.
What drives Toronto’s daily weather patterns?
Toronto’s weather is influenced by three main factors: the Great Lakes, prevailing westerly winds, and continental air masses. The lake keeps lakeside neighbourhoods cooler in summer and warmer in winter than inland areas.

Can I trust a 10-day Toronto forecast?
