With the FIA declaring a heat hazard for the Singapore Grand Prix weekend, a warm Sunday is expected at the Marina Bay Street Circuit.
Singapore GP Weather Forecast
Sunday – Ahead of the weekend, the FIA declared a heat hazard. After a quiet Friday and Saturday in terms of the weather, it’s expected to be around 30°C for today’s Singapore Grand Prix.
The track was wet during today's F1 Academy race, but it is expected to dry, with less than a 20% chance of rain at the Marina Bay Street Circuit today. The track temperature will range from 31 to 37°C. Wind gusts can reach up 5-15 kilometres per hour.

Heat hazard announced ahead of the weekend
The Marina Bay circuit, over the years, has proven to be one of the most humid venues on the F1 calendar. The race, which joined the F1 calendar in the 2008 season, has since been held at night due to the extreme heat that often affects the Marina Bay region during race weekends.
2025 is not expected to be an exception, and the FIA has swung into action to aid teams through the hot weather. In an announcement signed by race director Rui Marques, it declared a heat hazard for this weekend's outing. This will mandate teams to install cooling systems for their respective drivers.
“In accordance with Article 26.19 of the Sporting Regulations, having received a forecast from the Official Weather Service predicting that the Heat Index will be greater than 31.0 °C at some time during the race at this event, a Heat Hazard is declared.”
