Formula 1 heat hazard declared for fourth time this season

LONDON, United Kingdom, Oct 8 – The Singapore Grand Prix has been declared a heat-hazard race, the second weekend in a row that the designation has been used in Formula 1 and the fourth time this year. The definition allows teams to fit cooling devices to their cars that pump liquid through a vest worn by the driver to manage temperatures in the cockpit. A heat hazard is an official status for an event where it is forecast that temperatures will exceed 31C at some point during the race. It was first introduced in 2025.

A heat hazard is an official status for an event where it is forecast that temperatures will exceed 31C at some point during the race. It was first introduced in 2025.

This year’s race is also being held amid air-quality issues as a result of smog caused by fires in Indonesia. F1 is monitoring the situation, which also applied at last weekend’s Bahrain Grand Prix in Malaysia, but does not currently consider it a cause for major concern.

Singapore is close to the equator and has long been known as one of the most demanding for drivers – in 2024, George Russell and Lewis Hamilton were treated for heat exhaustion after the race.
