Through the afternoon, Toronto’s hourly forecast (see live above) shows a lake-moderated mix of sun and cloud, with temperatures easing into the single digits overnight. The breeze off Lake Ontario will keep the downtown core a few degrees cooler than inland neighbourhoods through the early evening.
How does the hourly pattern look for the rest of the day?
The live forecast above breaks down each hour, but a few trends stand out. Cloud cover is expected to increase after 4 p.m., with a slight chance of drizzle near the lake around 9 p.m. Temperatures will drop steadily after sunset, bottoming near 6 °C by midnight. Wind speeds remain light, 10–15 km/h from the southwest, so no wind chill concerns tonight.
Can I rely on this hourly forecast for planning tomorrow?
Yes. The hourly data updates frequently from Environment Canada’s regional model. For longer planning, pair it with the Toronto weather page’s toronto weather 14 day and toronto weather 7 days outlooks. If you need weather in toronto tomorrow at a glance, the hourly view here shows the morning commute will start near 8 °C with sunny breaks.

How accurate are Toronto’s hourly forecasts?
Environment Canada’s hourly outlooks are updated every six hours and typically accurate within 1–2 °C for the next 12 hours. For same-day planning, this is the most reliable source you’ll find.
Why does the lakeshore feel cooler than the hourly temperature indicates?
Lake Ontario’s cool surface temperature can drop the actual air temperature by 2–4 °C within a few blocks of the shore, especially in spring. The hourly forecast shows the official station reading, often taken inland at Pearson Airport.
