F1 2025 United States Grand Prix weather forecast - latest from Austin

The iconic Circuit of the Americas welcomes the United States Grand Prix this weekend to mark the 19th round of the 2025 F1 season.

The championship battle between Oscar Piastri and Lando Norris is well and truly heating up, with McLaren having wrapped up the constructors' championship last time out, meaning all focus is on the pair's fight to become McLaren's first drivers' champion since Lewis Hamilton in 2008.

Heading into the sprint weekend in Austin, Texas, Piastri is 22 points ahead of Norris, while four-time world champion Max Verstappen was 63 points behind Piastri, but after a disastrous double DNF for McLaren in the US GP sprint, Verstappen has picked up eight more points on his hunt for a fifth consecutive drivers' title.

Prior to the weekend's racing action, the FIA also announced that the conditions at this year's US GP classified as a heat hazard, with temperatures forecast to exceed 31 degrees Celsius.

So, here's the crucial weather forecast for the United States Grand Prix.

Following a glorious Friday weather-wise in which Verstappen shone as brightly as the conditions, Saturday's busy day of F1 action took place in under even more scorching conditions.

In Saturday's grand prix qualifying, drivers had to deal with temperatures of 35 degrees Celsius which had a shocking real feel of 40 degrees, with no rain bringing any kind of relief.

So how are things shaping up for the main event?

Sunday, October 19 - Race

Lights out for Sunday's United States GP is at 2pm local time (CDT), and conditions are forecast to be the coolest yet sunniest of the whole weekend.

To the delight of the drivers, temperatures will rest at 28 degrees Celsius for lights out, and they will actually feel more like 27, making for a much more pleasant day both at the wheel and in the crowd compared to the previous outings.

There will be more wind around COTA however, which may prove tricky for drivers heading into an uphill Turn 1, while humidity will have dropped significantly to just 21 per cent. There is currently a zero per cent chance of rain falling across the full grand prix distance.
