Formula 1 is returning to the home of "The Night Race" along the hot, humid, and intense streets of Marina Bay in Singapore.

This race is home to some of the 'best' racing on the F1 calendar and intense temperatures that challenge even the most seasoned F1 drivers.

For the past few years, Singapore has been extremely hot and humid, even with the race occurring under the cover of darkness. This year, for the first time, the FIA issued a 'heat hazard' allowing drivers to wear special cooling vests during sessions throughout the weekend.

Singapore has been home to victories by Carlos Sainz (Ferrari) in 2023 and Lando Norris (McLaren) in 2024 who both claimed victory over the then-dominant Max Verstappen. The Singapore Grand Prix is the only track, as a matter of fact, that Max Verstappen has never claimed a Formula 1 victory.

As things stand, the McLaren duo of Lando Norris and Oscar Piastri are still favored to win the race, but with a fall in performance last time out in Baku, Max Verstappen is the driver that all eyes are on.

Even with dominant seasons for these three drivers, weather can be a massive factor in Singapore.
