The Italian Grand Prix has been officially labeled a "heat-hazard" race due to persistently high temperatures in Italy following a summer heatwave. This designation is used by Formula 1 when it is predicted that temperatures will exceed 31°C at some point during the race. At the Monza circuit, located northeast of Milan, ambient temperatures are expected to reach the mid-30°C range throughout the weekend. Earlier in the week, temperatures peaked at 36°C near Milan's Linate airport, highlighting the severity of the heatwave. To help drivers cope with the extreme conditions, Formula 1 allows the use of a special cooling system. This system circulates cooled liquid, such as glycol, through a fireproof top worn under their racing overalls. While the use of this cooling kit is optional, drivers who choose not to use it must add 5kg of ballast to their car to balance the weight and maintain fairness in competition. Some drivers avoid the cooling system due to discomfort or because of past issues with the coolant running out before the race ends, which could leave them exposed to even higher temperatures. Inside an F1 car, cockpit temperatures can exceed 40°C, even when ambient temperatures are lower. Drivers are already required to wear multiple layers of fireproof clothing, along with a balaclava and helmet, which can make overheating a serious concern. The heat can affect both physical performance and safety, making the cooling system a valuable tool for drivers in extreme conditions. The Italian Grand Prix is the second race this season to be classified as a heat hazard. The first was the Austrian Grand Prix earlier in the summer, also affected by the same heatwave. As temperatures continue to rise globally, Formula 1 is increasingly relying on such measures to ensure the safety and competitiveness of its drivers in extreme weather conditions.
