The weather could play a decisive role at the Canadian Grand Prix 2026, with forecasts predicting a significant chance of rain for Sunday's Formula 1 race at the Circuit Gilles Villeneuve in Montreal.
While teams are expected to enjoy dry running during practice, Sprint qualifying and Saturday's Sprint weekend action, changing conditions on race day could create one of the most unpredictable races of the season.
With the 2026 Formula 1 cars yet to face a fully wet Grand Prix, the prospect of rain has already become a major talking point heading into Round 10 of the championship.

Why rain could have a huge impact on the 2026 Canadian Grand Prix
The Circuit Gilles Villeneuve has a long history of producing dramatic wet-weather races.
The most famous example remains the 2011 Canadian Grand Prix, which featured a rain delay lasting more than two hours before Jenson Button completed one of Formula 1's greatest comeback victories by overtaking Sebastian Vettel on the final lap.
More recently, changing weather conditions have frequently influenced strategy calls and Safety Car interventions in Montreal.
Only one of the last eight Canadian Grands Prix has been completed without some form of Safety Car appearance, underlining how challenging the circuit can become when conditions deteriorate.
Why teams are watching the forecast closely
Rain would represent a major unknown for the 2026 Formula 1 field.
The new-generation cars feature significantly different aerodynamic characteristics and power delivery compared to previous regulations, with drivers having limited experience pushing them to the limit in fully wet race conditions.
The combination of lower downforce, powerful engines and Montreal's unforgiving walls could increase the chances of mistakes, Safety Cars and strategic gambles.
With championship battles tightening and several teams introducing upgrades this weekend, Sunday's weather forecast may ultimately prove just as important as outright pace.
