Miami GP start time moved forward due to severe thunderstorm threat in Florida

The 2025 Miami Grand Prix start time has been moved forward three hours to 1 p.m. ET (6 p.m. UK) from its original 4 p.m. ET slot due to the threat of severe thunderstorms forecast to hit the circuit on Sunday afternoon. The FIA, F1, and Miami GP organizers issued a joint statement citing driver, fan, team, and staff safety as the primary reason for the schedule change. This marks the first significant Formula 1 weekend schedule alteration since the 2024 São Paulo Grand Prix.
