F1 drivers set for extreme weather at 2025 United States GP in Austin

F1 is set for a sweltering United States Grand Prix in Austin, with temperatures set to be in the mid-to-high 30-degree Celsius region. 

F1 heads to Austin to kick off the final quarter of the season, with the Sprint weekend set to be a hot one for the drivers - with the potential for another heat hazard to be declared.

Last time out in Singapore, with air temperatures set to reach 31 degrees Celsius, the FIA officially declared the heat warning, meaning cars were required to be fitted with the equipment for drivers to run the cooling vests, with these set to be mandatory from 2026, although the wearing of the actual vests was not required.

Current forecasts for the Austin weekend are for clear skies throughout with little to no chance of rain, and temperatures pushing up from 30 degrees, potentially peaking on Saturday at 35 degrees, according to BBC Weather.

The direction of the wind is set to change throughout the weekend, with gusts on Friday for practice and Sprint qualifying corresponding to a head-wind into Turn 1 - and a cross-wind from right-to-left through the Esses of Sector 1. 

For Saturday's Sprint and grand prix qualifying, this is set to change, with the wind coming from the south-west - a direct head-wind into the Turn 12 braking zone at the end of the back straight. 

For the main grand prix, this is to flip into gusts from the north-east, a tailwind down the straight into the braking zone.
