The Miami Grand Prix on Sunday will commence three hours earlier than initially planned, shifting from 4 p.m. local time to 1 p.m. local time (6 p.m. BST). This significant alteration, confirmed by a joint statement from the FIA, Formula 1 management, and the Miami Grand Prix organizers, aims to mitigate disruption from a forecast of heavy thunderstorms and lightning expected to strike the circuit later in the afternoon.
The decision, reached after meetings involving F1 stakeholders following Saturday's qualifying session, prioritizes completing the race within its maximum two-hour active run time and ensures a broader window to conduct the event under safer conditions. The revised schedule also impacts supporting races, with the Formula 2 feature race now slated to start at 9:25 a.m. local time.
Weather Dictates Schedule Change
Meteorological forecasts throughout the week pointed to an increasing likelihood of severe weather impacting the Miami International Autodrome on Sunday afternoon. While earlier projections suggested storms might arrive after the race, updated models have brought the timing forward, creating a high probability of encountering significant rainfall and lightning around the original 4 p.m. start.

Under strict United States regulations, any lightning detected within an eight-mile radius of the circuit necessitates an immediate suspension of all on-track activities, requiring personnel and fans to seek shelter. This protocol, known for causing considerable delays at US-based motorsport events, remains a key factor in managing the event's risk profile, even with the adjusted start time.
The Grid and Uncertainties
While the start time has been moved, the race is still expected to be affected by wet conditions. This introduces an element of unpredictability, as the performance of the cars, particularly the controversial new 2026 models, in the rain is largely untested. The influx of major upgrades from teams like McLaren, Red Bull, and Ferrari for this event further complicates predictions of race outcomes under such circumstances.
Background: A Season of Upgrades and Shifting Fortunes
The 2026 season has seen Mercedes holding a dominant early lead, with the team having secured victories in the first three Grands Prix and comfortable one-two finishes in both full and sprint qualifying sessions. However, for the Miami race, while Mercedes has introduced only minimal developments, its rivals have brought substantial upgrades. McLaren, Red Bull, and Ferrari are all deploying significant performance enhancements, aiming to close the gap. Mercedes, meanwhile, is reserving its major package for the subsequent race in Canada, where McLaren is also expected to introduce further new components. The shifting competitive landscape, now potentially exacerbated by unpredictable weather, adds another layer to the unfolding season.
