F1 2025 Brazilian Grand Prix weather forecast - latest from Sao Paulo

F1 returns to Sao Paulo for the Brazilian Grand Prix this weekend as the title race welcomes a new leader.

Lando Norris' victory at the Mexican GP saw him usurp McLaren team-mate Oscar Piastri at the top of the drivers' standings by a single point, and after the Brazilian sprint, the Brit is now nine points clear of his title rival.

Another podium finish for Max Verstappen last time out has kept him in championship contention, and a win in Brazil would be crucial for the Dutchman's title chances going forward.

The four-time champion will have his work cut out to make it to the podium at Interlagos on Sunday however as Red Bull are understood to have changed Verstappen's power unit and car setup, meaning he will have to start from the pit lane after breaking parc ferme regulations.

But not all hope is lost for the Dutchman, who returns to the scene of his spectacular victory in 2024 where he stormed from P17 in the wet to claim the Brazilian GP race win.

Will rain once again orchestrate chaos at Interlagos? Here is the full weather report ahead of Sunday's main event at the Brazilian GP.

Sunday, November 9 (Race)

The weather was less chaotic than expected at Interlagos on Saturday, but still managed to play a significant part in the on-track action.

After rain fell overnight on Friday, the track was still drying the following day, which led to damp conditions in the sprint race. This resulted in Piastri making the mistake of picking up water from the trackside kerb, which saw him spin out of control and make contact with the barriers.

The Aussie driver was unable to finish the 100km event as a result of the crash, with Alpine driver Franco Colapinto also suffering the same fate.

Sunday's main grand prix starts at 2pm local time (BRT), where a 40 per cent chance of rain is currently being forecast for lights out, before that threat slightly decreases throughout the race distance.

But once again, rain is expected overnight into Sunday morning, which will likely mean a damp track to start once again, or at the very least a track that has had its marbles from the previous days' running washed away.

Temperatures will drop to a positively cool 19 degrees Celsius compared to Friday and Saturday, while wind speeds also lessen to 11mph and provide a headwind on the start/finish straight. Teams who struggle to warm their tyres could face difficulty this weekend.

Humidity remains relatively high for the Brazilian GP, with the current forecast suggesting that drivers will have to deal with highs of 66 per cent humidity in the cockpit for the 21st round of the 2025 campaign.
