Mississauga’s weather today is typical for southern Ontario: a mix of sun and cloud, with temperatures near the seasonal average. The live forecast above gives the current conditions and any alerts. Expect a chance of rain in the afternoon as a weak system passes through.
What should I plan for today’s weather in Mississauga?
Check the live forecast above for exact timing, but the general pattern is a mild morning followed by increasing cloud. Showers are possible after 2 p.m. Winds stay light from the southwest. If you’re heading out, bring a light jacket and an umbrella — the rain won’t be heavy but could last an hour or two.
How does the rest of the week look?
Behind today’s system, cooler air moves in for Wednesday. Highs drop a few degrees, and skies clear overnight. Thursday and Friday stay dry with temperatures near 20°C. No major storms are expected, so outdoor plans should hold up. For a full outlook, see our Weather 10 Days page.
Will the rain last long in Mississauga today?
No. The showers are associated with a fast-moving low. Most areas will see rain for 30 to 60 minutes between 2 and 5 p.m. Clearing begins by early evening, so outdoor evening events should be fine.
Is there any heat warning or special alert?
Not today. Temperatures stay below warning thresholds. Check the live forecast above for any watches or statements from Environment Canada. If you’re traveling further east, Toronto weather may differ slightly.
How does Mississauga weather compare to nearby cities?
Mississauga is often a degree or two warmer than downtown Toronto due to lake effects. Conditions here are similar to Ottawa weather in April but milder in spring. Always use local data from the live forecast above for decisions.
