Grand Prix weekend: rain moving in Sunday
Montréal's F1 weekend starts sunny but clouds gather—Saturday evening showers possible, Sunday race day looking wet.
Grand Prix weekend is almost here, and the weather gods are playing their usual game. Thursday and Friday look solid—clear skies, temperatures hovering in the mid-teens to low 20s Celsius, rain chances hovering around 10 percent. Parties will flow indoors and out. The Sprint Qualifying on Friday afternoon should be clean.
Then Saturday arrives, and things get interesting. Morning stays sunny, warming to a pleasant 19°C by afternoon—the Sprint at noon and Qualifying at 4 p.m. should be fine. But come evening, shower chances jump to 60 percent. One to three millimetres of rain could fall after dark. If you're planning outdoor events Saturday night, the jacket stays packed.
Sunday is the wild card. Race day at 4 p.m. arrives under a 60–70 percent rain forecast, with showers likely all day and overnight. It's not new for Montréal's Grand Prix—rain has derailed plenty of editions over the years—but it does mean the main event could be a wet one. The track typically opens up under those conditions; visibility drops; strategy becomes everything.
In short: enjoy the first two days, gear up for Saturday evening, and prepare for the possibility of another wet race come Sunday. The weather forecast for Grand Prix weekend is as unpredictable as the racing itself.
