For Toronto, the live forecast above shows mainly cloudy skies with a chance of showers late in the week as a mild Pacific air mass filters into southern Ontario. This pattern is typical for early spring, keeping temperatures near seasonal norms while the lake-effect machine winds down.
What’s driving this week’s weather?
A broad trough over Hudson Bay is steering weak systems across the Great Lakes, bringing periods of rain but no major storms. High pressure built over the U.S. Midwest is keeping the core of the cold air north of the city, so Toronto will see daytime highs close to the long-term average for this time of year. A warming trend is expected by the weekend as southwesterly flow strengthens. For a broader look at conditions across the country, visit the Canada weather hub.
How will Lake Ontario influence local conditions?
Lake Ontario’s water temperature remains cold enough to prevent organized lake-effect snow, but the open water can still generate patchy fog on cool, calm mornings. Onshore breezes may keep the lakeshore a degree or two cooler than inland neighbourhoods like Scarborough or North York. For the full Toronto outlook, see the Toronto Weather page.
Will it rain heavily this weekend?
Rain is likely on Saturday under a passing low, but totals should stay under 10 millimetres. Sunday looks mostly dry with clearing skies. Check the live forecast above for hour-by-hour updates.
When will temperatures warm up?
Daytime highs should climb a few degrees by Friday, approaching 8–10°C. Overnight lows will remain near 1–3°C, so frost is unlikely in the urban core but possible in outlying areas.
