The 2025 Belgian Grand Prix is set to continue an engrossing Formula 1 season at the historic Spa-Francorchamps circuit, with the weather once again playing a significant role as, in classic fashion, rain is poised to disrupt the weekend.
Located in the Ardennes forest, Spa is renowned not only for its demanding layout and iconic corners but also for its unpredictable microclimate, where conditions can vary drastically even between track sectors.
This year’s event, taking place from July 25 to 27, will feature a Sprint Race format, heightening the importance of every session and early forecasts suggest the weekend could be marked by intermittent rain, throwing a major spanner into the works.
This could ultimately impact set-up choices, whilst also putting a greater emphasis on making sure tyre strategy is spot on. Finally, the slippery conditions promotes adaptability from the drivers, who can ‘out-perform’ their cars as Nico Hulkenberg did for Sauber.
Without further ado, here is the weather forecast for the F1 2025 Belgian Grand Prix at the Circuit de Spa.
Friday, July 25: Rain possible for Sprint Qualifying
The race weekend begins on Friday with Free Practice 1 at 12:30 local time (CET), followed by Sprint Qualifying at 4:30pm CET. Morning conditions are expected to be overcast, with light drizzle possible early on.

By FP1, clearer skies are forecast, and the ambient temperature should sit around 20°C. However, weather conditions are expected to deteriorate later in the day.
Sprint Qualifying is likely to be affected by rain, with a 60% chance of light to moderate showers after 3pm CET local time.
Saturday, July 26: Will it rain for the F1 Sprint Race?
Saturday’s schedule sees misty conditions in the morning, which are forecast to clear before the Sprint Race, with ambient temperatures reaching 22°C. So this should be dry running – on paper.
Whilst later in the afternoon, temperatures may rise slightly to 23°C during qualifying and rain is not currently expected. But it is important to note that conditions at Spa can shift quickly, and teams will remain alert to any late changes.
This caught Mercedes out in 2021 as they opted for a low-drag rear-wing for Sunday at the expense of securing pole position for Lewis Hamilton.
The cancelled race then cost him valuable points against Red Bull’s Max Verstappen in their infamous and memorable title battle.
Sunday, July 27: Is rain expected for the F1 2025 Belgian Grand Prix?
Race day on Sunday brings the greatest risk of weather disruption as the current FIA outlook predicts a high probability of light, intermittent rain throughout the day, especially in the afternoon.
With the Grand Prix set to begin at 15:00, a 60% chance of precipitation could significantly impact tyre strategy and pit stop timing whilst also allowing drivers and cars uncompetitive in the dry conditions to get into the mix.
Fans should look to the likes of Verstappen to take the fight to the McLarens in such conditions, whilst Fernando Alonso, Esteban Ocon and Nico Hulkenberg could also score big results.
Storylines to watch out for at F1 2025 Belgian Grand Prix
It’s a big weekend for Red Bull, who face their first Grand Prix without Christian Horner, replaced by Laurent Mekies, in a dramatic mid-season leadership change which comes amid a sharp drop in performance and results.
The move could keep Verstappen with the team, as the defending champion’s future remains uncertain in the wake of strong links to Mercedes, fuelling questions about his long-term commitment heading into Spa.
Will they get their form back on track? In recent weeks, they have been outscored by Sauber and Hulkenberg’s breakthrough podium at Silverstone came at the expense of Verstappen after his spin.
It marked Sauber’s first in 13 years and recent upgrades have propelled them to fourth-highest scoring team over four races, raising hopes of continued competitiveness at Spa as they look to take momentum into their switch to Audi.
Whilst at the front of the field, McLaren’s Lando Norris and Oscar Piastri are poised to continue their battle over the Formula 1 title. Britain’s Norris has now won three of the last five races, so his Australian colleague needs to bounce back.
