Race day at the Circuit of the Americas is set to unfold under clear Texas skies, with no threat of rain and plenty of sun throughout the afternoon.
Temperatures will begin in the mid-20s°C (77°F) around lights out and peak near 31°C (88°F) by the race’s end.
Track temperatures are expected to climb well above 40°C (104°F), pushing tyre management and cooling strategies to the forefront for teams.
But the most critical factor shaping the United States Grand Prix could be the wind.
Forecasts indicate a steady northeast wind ranging between 15–20 km/h (9–12 mph), with gusts reaching up to 35 km/h (22 mph) during the race.
This shift from the southwesterly winds seen earlier in the weekend will bring a notable tailwind down the long back straight (Turn 11 to Turn 12) — potentially increasing top speeds and reducing downforce under braking into one of the circuit’s key overtaking zones.
Crucially, the Esses section (Turns 3–9) will see a crosswind that could unsettle the cars mid-corner. Drivers will need to remain sharp, as wind-induced instability in these high-speed changes of direction may lead to snap oversteer or reduced grip, particularly as tyres wear.
In braking zones and into slower corners, aero sensitivity combined with unpredictable gusts may result in variability in balance lap to lap — especially for teams running lower downforce setups.
For fans trackside, it will be a warm, breezy afternoon — ideal spectating weather, though those in open seating should expect the occasional strong gust.
