Overview
- The latest forecasts published May 21 put Sunday’s rain chance at about 60 percent, with ambient temperatures near 17°C and stronger SSE winds that increase the chance of a wet race.
- Ferrari team principal Fred Vasseur warned May 21 that cooler spring conditions will add complexity for teams trying to hit tyre operating windows during the sprint-format weekend.
- Circuit Gilles Villeneuve’s stop–go layout produces long straights into heavy braking zones that stress brakes and tyres and make it harder for tyres to reach optimal temperature when ambient readings fall below 20°C.
- Teams will face a narrow preparation window because sprint rules give just a single 60-minute free practice session, so many squads plan to keep wet tyres on standby and adopt flexible race plans.
- Montreal’s move from June to late May as part of F1’s North American scheduling has increased the likelihood of cool, changeable weather at the track and could affect pit strategies, tyre life and on-track safety.
