Heavy thunderstorms threaten to disrupt the 2026 Miami Grand Prix

Formula 1’s return to action at the Miami Grand Prix is facing an escalating threat from severe weather, with heavy thunderstorms forecast to disrupt Sunday’s race.

As teams prepare for round four of the 2026 season, meteorological models indicate a significant storm system is on a collision course with the city. At 0600 ET on Wednesday, April 29th, forecasts predict heavy thunderstorms will blow through Miami on Sunday morning, lingering well into the afternoon ahead of the scheduled 16:00 local time start for the 57-lap race.

A massive storm system on the move

The weather system threatening the 2026 Miami Grand Prix is vast in scale. Having formed earlier in the week in the Rockies near Denver, Colorado, the storm is projected to impact most of the eastern seaboard of the United States.

Before reaching South Florida, the system will track across the southern states of Alabama, Louisiana, and Mississippi throughout Friday and Saturday. It is then expected to cross the Florida panhandle late Saturday night into Sunday morning before finally hitting Miami. From there, the storm cells will continue moving from the north-west to the south-east, passing over Cuba and the Bahamas before heading out into the Atlantic Ocean.

Echoes of 2025: the threat of aquaplaning

If the skies open on Sunday, it will not be the first time the Miami Grand Prix has been thrown into chaos by torrential rain. In 2025, the Sprint race was severely impacted by thunderstorms, leading to a delayed start under red flag conditions. The treacherous track surface caught out several drivers, most notably Charles Leclerc, who aquaplaned off and crashed on the lap to the grid prior to the start.

However, the 2025 event also proved that the Miami circuit can dry rapidly. Once the rain ceased, track conditions improved quickly enough for drivers to switch to slick tyres by the end of the shorter race. Teams will undoubtedly factor this rapid drying characteristic into their strategic calculations if Sunday's race begins on wet weather tyres.

Sweltering heat for Practice and Qualifying

While Sunday’s Grand Prix is under a severe weather watch, the rest of the weekend is expected to remain dry. The heat and rain threaten to disrupt strategy across the board, as temperatures are forecast to soar into the low to mid-30 degree Celsius range.

These sweltering conditions will persist throughout practice, Sprint Qualifying, the Sprint race, and the main Qualifying session. The stark contrast between a scorching, dry build-up and a potentially torrential Sunday will force teams to make critical setup compromises, adding another layer of complexity to an already demanding weekend in South Florida.
