F1 2026 Canadian Grand Prix weather forecast - latest from Montreal

All eyes are on the skies this weekend as F1 returns for the Canadian Grand Prix - especially after the Miami Grand Prix start time was moved due to storms in the area.

Spoiler alert: those skies look very grey, and very ready to wreak havoc on Notre Dame Island.

The Canadian GP has been pushed forward compared to its usual June slot on the calendar, for sustainability and logistics reasons, as well as to avoid the usual clash between the Monaco Grand Prix and the Indy500, two legs of motorsport's historic triple crown.

Montreal's Circuit Gilles Villeneuve plays host to round five of the 2026 season, and fans will be hoping for a similar level of drama to what we saw in 2025's event.

Title challengers Oscar Piastri and Lando Norris came together, hampering Norris' title hopes against his team-mate.

This year, Mercedes' drivers George Russell and Kimi Antonelli are the ones fighting for the title, with 19-year-old Antonelli leading by 20 points in the standings after three consecutive grand prix wins.

But Russell claimed victory in Canada last year and will be looking to do so again to put pressure on the Italian teenager.

F1 Canadian Grand Prix weather forecast

Sunday, May 24: Race day

Amid the extended sprint weekend schedule, the main event is still the grand prix, with lights out on Sunday for the Canadian Grand Prix taking place at 4pm local time (EST).

Sunday's forecast has taken a turn for the worse, with temperatures plunging to a chilly 13 degrees Celsius.

The chance of rain for the start sits at 66 per cent as we approach race time, and sits at that figure throughout the two hour window when the race is expected to run.

Keep your eyes glue to the rain radar though, because there's a very real chance that the rain falls in the area but skirts around the track itself. It happens more than you'd think!
