Formula 1 has brought forward the start time of the Miami Grand Prix due to severe thunderstorm forecasts, with the FIA confirming that this decision was made to maximise the chances of completing the race safely.
The fourth round of the 2026 season will now begin at 18:00 BST on Sunday, three hours earlier than originally planned.
The FIA acted early to avoid weather disruption
Organisers confirmed the schedule change ahead of race day in response to deteriorating weather forecasts across southern Florida. The threat of the race being potentially cancelled completely due to dangerous weather was reported by this website early.
The Grand Prix was initially scheduled to start at 9:00 pm BST, but officials decided to bring the race forward to allow more time to complete the event before the storms intensify later in the evening.
In an official statement, the FIA explained the reasoning behind the decision:
“This decision was made to minimise disruptions during the race and to ensure the largest possible timeframe for a successful conclusion to the Grand Prix under optimal conditions. The safety of drivers, fans, teams and staff is our top priority.”
This proactive approach reflects previous weather-related interruptions at the venue, with the championship keen to avoid delays or a potential race suspension.
US safety regulations influenced the decision
The urgency of the change is also influenced by strict local safety laws in the United States.
These regulations require the immediate suspension of outdoor sporting events in the event of thunderstorms or lightning, necessitating the movement of spectators and personnel to safe shelter.
This creates a narrow operating window for Formula 1, particularly in Miami, where sudden storms are common. By advancing the start time, officials aim to reduce the risk of the race being halted midway through or cancelled altogether.
Miami weather remains a known challenge
Unpredictable weather has already caused disruption to events at the Miami International Autodrome in the past.
During last year’s event, for example, heavy rain delayed the sprint race and posed logistical challenges for teams and organisers alike. Similar conditions are forecast again this weekend, with thunderstorms expected during the original race window.
The circuit’s flat layout further complicates matters, as standing water can quickly accumulate and reduce visibility.
Several drivers have expressed concerns about racing in such conditions in the current generation of cars.
Carlos Sainz warned: “It’s an extremely flat track, the water stays on the surface, and whether it will be safe enough with the nearby barriers and the visibility we have with these cars will certainly be a cause for concern.”
Regulation tweaks target wet-weather safety
Ahead of the Miami weekend, Formula 1 introduced a series of regulatory adjustments aimed at improving safety in wet conditions.
To improve grip with intermediate tyres, the permitted temperature of tyre warmers has been increased. Visibility measures have also been addressed, with simplified rear light signals designed to make cars easier to see in spray-heavy conditions.
Additionally, the maximum output of the ERS system has been reduced to improve car control when traction is limited. The use of the overtaking boost button has also been temporarily restricted in scenarios involving heavy rain.
These changes come amid broader concerns from drivers about their limited experience of driving the 2026-spec cars in wet conditions, given the differences in aerodynamics and handling compared to previous seasons.
Ecclestone era vs modern flexibility
The decision to change the start time of the Miami Grand Prix highlights just how much Formula 1’s approach has evolved compared to the Bernie Ecclestone era, when race schedules were rarely adjusted once set.
From the late 1980s through to 2017, Ecclestone’s commercial model was built around rigid global television contracts. Race start times became increasingly standardised — most notably the long-standing European 2:00 pm slot — to satisfy broadcasters across multiple markets and guarantee consistent programming windows.
The importance of television dictated virtually every aspect of scheduling. As the sport expanded globally, it became essential to deliver a reliable, fixed broadcast product, with billions of viewers tuning in worldwide.
Under Ecclestone, changing a start time at short notice — particularly by several hours — would have been extremely difficult due to contractual obligations with broadcasters and tightly coordinated international schedules.
The 1976 Japanese Grand Prix serves as an early warning
One of the earliest examples of broadcast-driven inflexibility occurred at the 1976 Japanese Grand Prix at Fuji.
The race, which would decide the title, took place in torrential rain despite the extremely dangerous conditions.
As the event was scheduled for global satellite broadcast to Western audiences, there was little appetite to delay or significantly alter the start time. The race went ahead as planned, despite visibility issues and standing water pushing safety to the limit.
Lauda withdrew after just two laps, citing unacceptable risk, while Hunt continued and secured the championship. These conditions have since become symbolic of a very different era in safety decision-making.
Television’s influence grew throughout the 1980s and 1990s
By the time Formula 1 entered its commercial boom under Ecclestone, broadcasters’ influence had only intensified.
Start times became increasingly uniform, particularly in Europe, to ensure consistency for major television partners. The idea of moving a race to avoid bad weather, especially on race day, was largely impractical within such a tightly controlled framework.
Even as safety standards improved in other areas, scheduling remained one of the least flexible elements of the sport’s operations.
The Miami adjustment clearly highlights this shift. While television once dictated immovable start times, the sport can now prioritise safety and race completion, even if it means making last-minute changes.
This flexibility represents a fundamental change in philosophy, moving away from a system where operational decision-making was dictated solely by broadcast demands to one where it is balanced against real-time conditions and safety considerations.
