The FIA has officially declared a Heat Hazard for the upcoming Italian Grand Prix, scheduled for this weekend, as temperatures are anticipated to surpass 31 degrees Celsius. This announcement is part of a new guideline introduced for the 2025 season, aimed at ensuring driver safety during extreme weather conditions.
Under this guideline, teams have the option to equip their cars with advanced driver cooling systems throughout the race weekend. While these systems are not mandatory, teams that choose not to use them will need to add ballast to their cars to compensate for the additional weight of the cooling devices, which is approximately 5 kilograms.
Rui Marques, the FIA Formula 1 Race Director, explained the rationale behind the Heat Hazard declaration. In a statement, he noted, “In accordance with Article B1.5.10 of the FIA F1 Regulations, having received a forecast from the Official Weather Service predicting that the Heat Index will be greater than 31.0 °C at some time during the Race at this Competition, a Heat Hazard is declared.” This precautionary measure reflects the FIA's commitment to driver welfare, especially in challenging weather conditions.
The forecast for the race weekend indicates that Friday's sessions could see temperatures reaching 33 degrees, with Saturday and Sunday expected to peak at 34 degrees. These high temperatures can significantly impact driver performance and safety, making the implementation of cooling systems particularly relevant.
The concept of a Heat Hazard was first introduced during the sweltering 2025 Singapore Grand Prix and was also applied at the 2026 Austrian Grand Prix. The FIA's proactive approach in declaring such hazards demonstrates an increasing awareness of the challenges posed by extreme weather in motorsport.
According to Article 26.19 of the FIA F1 Sporting Regulations, drivers have the option to forgo wearing personal equipment that is part of the Driver Cooling System. However, if they choose this route, all other components of the cooling system must still be installed in the car, and an additional 0.5 kilograms of ballast must be added to the cockpit to maintain weight regulations.
George Russell, a driver for Mercedes and director of the Grand Prix Drivers' Association, shared insights about the cooling devices. He remarked, “We’ve used the driver cooling vest already a few times at the hot races, but this is the first time it’s been mandatory. I think it’s good news. Not everybody finds the top comfortable, but over time you’ll be able to adjust it to your own preferences.” Russell emphasized the importance of these devices, particularly in humid conditions where cockpit temperatures can soar, making it feel like a sauna inside the car.
As the Italian Grand Prix approaches, the implementation of these cooling systems will be closely monitored, and their effectiveness in enhancing driver comfort and safety will be evaluated during the race weekend.
