Miami GP Start Moved Three Hours Earlier to Avoid Thunderstorms

Originally set for 4 p.m. local time on Sunday, the race was rescheduled after forecasters showed heavier rainstorms likely later in the afternoon. The change mirrors last year’s situation when similar weather forced interruptions to support races. Florida’s statute is among the strictest in the U.S., mandating an immediate stop to any outdoor activity when lightning is detected. The adjustment also affects support races scheduled for Saturday, which retain their original times. Officials say the change minimizes disruption to the overall weekend programme.

The start time shift is three hours earlier, moving the race to 1 p.m. local time. FIA, F1 and the Miami promoter cited the later‑afternoon rainstorm forecast as the reason for the change. Under Florida law, any thunderstorm risk obliges organizers to halt the event instantly, meaning the Grand Prix could be suspended mid‑race if conditions deteriorate.

The earlier start shifts the broadcast window for U.S. viewers, potentially increasing early‑afternoon TV ratings but reducing prime‑time exposure. Teams must adjust tyre strategies and pit‑stop plans for a cooler, drier track early in the day. Fans attending the circuit will experience morning heat instead of late‑afternoon warmth, affecting concession sales and crowd flow. The race remains vulnerable to a sudden stop; if lightning is detected, the FIA will follow the suspension procedure used in 2025, returning cars to the pitlane and awaiting a safe window to resume.
