2025 F1 Belgian Grand Prix weather update: Will it rain at Spa?

How rain and cool air will impact Sunday’s F1 showdown in Belgium

-

The legendary Spa-Francorchamps circuit is set to live up to its unpredictable reputation for the 2025 Belgian Grand Prix, with weather forecasts pointing to a cool and wet Sunday that could upend the race. As teams and drivers prepare for lights out at 3:00 pm local time, all eyes are on the skies above the Ardennes, where rain is more likely than not and conditions are expected to remain challenging throughout the afternoon.

Weather at Spa has always been a wild card in Formula 1, and this year is no different. Heading into race day, a series of heavy downpours overnight and into the morning hours have left the circuit soaked. Although a brief window of drier conditions is forecast around midday, all signs point to the return of showers by the time the grid lines up, making tire strategy and adaptability crucial from the very start.

A Wet and Chaotic Belgian GP 2025 Likely at Spa

At the scheduled 3:00 pm race start, Spa is expected to be cool, with air temperatures hovering around 17 to 18 °C—mid-60s in Fahrenheit. These cooler temperatures mean the track will struggle to dry quickly, especially with high humidity in the air. Forecasts put relative humidity at roughly 80 percent during the race, which will make the atmosphere feel muggy and prevent any brief dry spells from evaporating the moisture that’s already soaked into the circuit.

The big talking point is the likelihood of rain. Local and international weather services are in rare agreement, projecting anywhere from a 60 to 90 percent chance of rain when the lights go out. The UK Met Office, for instance, is predicting a 90 percent chance of precipitation at race start, only tapering slightly as the afternoon wears on. Thunderstorms are also possible, adding another layer of unpredictability for teams hoping to make the right call on tires and setup.

Winds are expected to be light to moderate, mostly from the northwest at about 10 km/h, occasionally gusting up to 25 km/h. Later in the day, the wind could shift to a more westerly direction, introducing a crosswind through some of Spa’s fastest and most technical sections, such as Eau Rouge. While wind speed is unlikely to be a deciding factor, even a slight breeze at these high-speed corners can catch drivers off guard, particularly in wet conditions.

Track conditions at Spa will almost certainly be wet or damp at the start, with the possibility of standing water in some areas if heavy showers persist. Even if the rain lets up momentarily, the track will take time to dry due to the cool air and lack of direct sunshine, meaning intermediate or even full wet tires are likely to be the choice for the opening laps. Teams are preparing for a race that could be dictated as much by the weather as by pace, with the chance for chaos and upsets if conditions shift quickly or unexpectedly.
