Qualifying for the 2026 Formula 1 Sao Paulo Grand Prix faces a significant threat from severe thunderstorms and torrential rainfall at the Autódromo José Carlos Pace. The weather conditions deteriorated rapidly following the final practice session on Saturday, November 7, 2026.
A substantial clap of thunder and lightning was reported in the Interlagos region at 13:15 local time, 45 minutes after the conclusion of Free Practice 3. This was immediately followed by a heavy downpour.
The FIA granted teams permission to close their garage doors as temperatures dropped considerably. The current air temperature is approximately 22°C.
Forecasts indicate a 50% probability of significant rain or thunderstorms during the qualifying session, which is scheduled to begin at 15:00 local time. Precipitation is more likely after 14:00.
Light to moderate winds, with gusts potentially reaching 50 km/h, are also expected. Localised urban flooding and standing water on the track are possible.
Interlagos is renowned for its volatile climate and is situated in Sao Paulo’s thunderstorm season. The circuit’s elevation changes and hillside location contribute to rapid storm formation through orographic lift.
Historically, wet weather has been a major factor in qualifying at Interlagos in three of the last four seasons. The 2024 Sao Paulo Grand Prix qualifying was postponed to Sunday morning due to a severe storm.
For the 2026 season, the FIA introduced a new “Rain Hazard” rule to manage uncertain weather. This regulation allows limited setup changes between qualifying and race day if a rain hazard is declared.
A rain hazard is declared if the official weather service forecasts a 40% or higher probability of precipitation. The declaration must occur no later than two hours before qualifying commences.
Under this rule, teams are permitted to adjust ride height and wing incidence angle to increase ground clearance and reduce downforce. This aims to enhance safety for ground-effect cars in wet conditions.
However, alterations to spring rates, damper settings, differential maps, and brake duct specifications remain prohibited. The FIA also banned boost mode usage in wet races for 2026 to improve traction control.
In Free Practice 3, Max Verstappen recorded the fastest time, a 1:11.622 on soft tyres. Kimi Antonelli was second for Mercedes, just 0.025 seconds behind.
Lando Norris secured third position for McLaren, with George Russell and Charles Leclerc completing the top five.
Lewis Hamilton’s session was compromised by a vibration and subsequent smoke from the rear of his Ferrari, limiting his running.
Verstappen, Sergio Pérez, Hamilton, and Leclerc are all facing grid penalties for power unit component changes. Verstappen will start from the back of the grid due to accumulating 30 places worth of penalties.
Pérez also incurs a grid drop, while Hamilton and Leclerc each face 10-place penalties. These penalties add a further strategic dimension to the impending qualifying session.
