Over the next seven days, Montreal will see a mix of sun and cloud with temperatures near seasonal norms, though a mid-week system could bring a few millimetres of rain. The live forecast above shows the daily highs and lows for the week ahead.
What is the outlook for the next seven days in Montreal?
Montrealers can expect a fairly typical late-spring pattern this week. Daytime highs will hover around the low 20s Celsius, with overnight lows dropping to the single digits. The most notable feature is a low-pressure system expected to move through the St. Lawrence River valley around mid-week, likely bringing a period of steady rain and gusty winds. Conditions should clear by the weekend, offering a pleasant stretch for outdoor plans along the Lachine Canal or Mount Royal.
Will there be any drastic temperature swings?
No major extremes are anticipated. The temperature range over the seven days is relatively narrow, with no heat warnings or frost advisories currently in effect. This stable pattern is a relief after the variable conditions seen earlier in the month. For those checking the weather montreal 7 days hourly forecast, the most significant shift will be the drop in temperature immediately following the rain system.
Frequently Asked Questions

Tomorrow’s forecast calls for a mix of sun and cloud with a high near 20°C and a low around 10°C. No precipitation is expected, making it a good day for a walk in the Plateau. Check the live forecast above for the exact hourly breakdown.
How does this week compare to the weather in Montreal 10 days?
The seven-day outlook is more settled than the latter part of a 10-day view, which often introduces greater uncertainty. The second half of a 10-day forecast could show more cloud or a shift in the jet stream, but the coming week looks stable.
Is a 30-day forecast reliable for Montreal?
A weather montreal 30 days outlook is a broad trend guide only, not a specific prediction. Day-to-day accuracy drops significantly beyond seven days. For trip planning, rely on the seven-day forecast above and check back closer to the date.
