Miami GP start time moved as FIA races against severe thunderstorms

The FIA has moved the start time of the Miami Grand Prix to 13:00 local time (18:00 BST) in a pre-emptive bid to avoid a severe thunderstorm system forecast to hit the circuit later on Sunday afternoon. While the oppressive heat of Friday and Saturday has subsided, the new threat of heavy rain, hail, and lightning now dictates the race schedule.

Why it matters:

Proactive schedule changes are critical in F1 to ensure both the safety of the event and the integrity of the competition. A red-flagged race due to extreme weather can create logistical chaos and an unsatisfying outcome for fans and teams. This move highlights the increasing role of precise meteorology in modern grand prix planning.

The details:

• The decision was made based on forecasts showing two distinct waves of storms approaching the Miami International Autodrome.
• The first wave, with lighter rain, was expected overnight into Sunday morning.
• A second, more intense wave bringing heavy showers, thunder, and potential hail is predicted for late afternoon into early evening.
• By starting the race at 13:00 local time, officials aim to complete the grand prix in the window between these two weather systems.
• Track temperatures are also forecast to be cooler, around 24-26°C, compared to the sweltering 30°C+ conditions experienced earlier in the weekend.

What's next:

While the timing is calculated to avoid the worst of the weather, Miami's volatile climate offers no guarantees. The race could still be affected by residual rain or an earlier-than-expected arrival of the second storm cell. All teams will now be preparing for a potentially mixed-condition race, adding a major strategic variable to the event. The success of the FIA's gamble will only be clear once the checkered flag falls—hopefully before the skies open.
