Over the coming 14 days, Mississauga will see a typical early-spring transition: daytime highs climbing from near freezing into the low single digits, with a few rain or wet snow showers, especially near the Lake Ontario shore. As shown in the live forecast above, the pattern is unsettled but not extreme.
How will lake effect and nearby Toronto conditions shape the outlook?
Mississauga’s position along Lake Ontario means a cool onshore breeze can keep temperatures a degree or two lower than inland suburbs, particularly on clear nights. The 14-day range, based on the live forecast above, shows highs between -1°C and 8°C, with lows from -8°C to 2°C. A few systems crossing from the U.S. Midwest could bring rain or flurries around days 5 and 10, but no major storms are signalled at this point. For a broader regional view, check our Toronto weather page for nearby comparisons.
Can I get a longer-term look, say 21 or 30 days for Mississauga?
While the weather mississauga 14 days forecast is the most reliable range, our data providers also offer a 21 day weather forecast mississauga and a free 30 day weather forecast mississauga. Those longer outlooks are useful for trend-spotting but become less precise after two weeks.

Will it snow in Mississauga in the next 14 days?
Light snow or flurries are possible, especially early in the period when overnight lows drop below -6°C. Accumulation should stay under 5 cm, with rain mixing in by the second week as daytime highs climb above 4°C.
When is the warmest day expected?
Based on the live forecast above, the warmest day looks to be around day 11 or 12, with a high near 8°C and mostly cloudy skies. That mild spell may bring a brief taste of spring before a cooler return.
How does Mississauga’s 14-day forecast compare with Toronto’s?
Toronto, just east along the lake, runs about 1°C warmer on average due to its urban heat island. Mississauga often sees stronger lake breezes, so morning temperatures can lag behind. Check our Canada weather hub for city comparisons.
