The Bahrain Grand Prix in Malaysia has been declared a heat hazard due to expected high temperatures at the Sepang International Circuit. Temperatures are forecast to reach 32C to 35C throughout the weekend, triggering the heat hazard status when conditions exceed 32C. This allows teams to fit driver cooling systems, with the minimum car weight increased to accommodate the extra equipment.
The cooling vest is optional; drivers who forgo it must carry 5kg of ballast. Similar heat hazard declarations were made for the Austrian and Italian Grands Prix earlier this year. The combination of high-speed racing and intense heat and humidity at Sepang makes this one of the most challenging weekends on the Formula 1 calendar for drivers and teams alike.
