The FIA has issued a ‘heat hazard’ declaration for the 2026 Italian Grand Prix at Monza, reflecting concerns over the forecasted high temperatures during the race weekend. This precautionary measure is based on weather predictions indicating that the heat index could exceed 31°C, posing potential risks to drivers and teams.
Following the FIA’s review after the 2023 Qatar Grand Prix, new protocols for extreme heat conditions were introduced starting from 2025. Under these regulations, all Formula 1® cars participating in the Italian Grand Prix must be equipped with a Driver Cooling System. This system is designed to help manage driver temperatures by circulating cold fluid through a fireproof vest worn by the driver, although wearing the vest remains optional.
The cooling system comprises several components including a pump, plumbing, and a thermal store, which together deliver the cooling fluid to the driver. If a driver chooses not to wear the cooling vest, a ballast of 0.5kg must be added to the car to account for the weight difference. This approach aims to maintain fairness while providing teams and drivers with flexibility in managing heat stress during the race.
Monza is expected to experience air temperatures above 30°C, potentially reaching the mid-30s Celsius, which justifies the FIA’s heat hazard declaration. This step reflects the governing body's ongoing efforts to safeguard driver health and performance under challenging environmental conditions.
Oscar Piastri of McLaren has previously used the cooling vest and shared his experience, noting that while it provides some relief, it is not a complete solution. He also mentioned that the effectiveness of the vest can vary depending on personal preference and that there are still some imperfections to be addressed.
Drivers will have the chance to test and familiarize themselves with the cooling system and vest during the first practice session on Friday. This opportunity allows them to assess the equipment’s comfort and impact ahead of the race.
The heat hazard declaration and the associated cooling system requirements apply to all 22 drivers and teams competing at the Italian Grand Prix. The FIA’s measures are part of a broader strategy to adapt Formula 1® regulations to evolving climate challenges, ensuring safety without imposing mandatory usage of cooling vests on drivers.
These developments underline the FIA’s commitment to addressing environmental factors that affect race conditions and driver wellbeing. The Italian Grand Prix at Monza will serve as a key event to observe how these heat management protocols function in practice under high-temperature conditions.
