Overview

• Sunday’s Belgian Grand Prix is poised to run in cool, humid conditions with a 70 to 82 percent chance of rain and potential thunderstorms at Spa-Francorchamps.
• Following dry sprint and qualifying sessions, several teams have reverted from low-drag to high-downforce rear wings to optimize grip on expected wet asphalt.
• Forecasts from sources like GPFans and The Weather Channel diverge on rain timing and intensity, underscoring the challenge of finalising race strategies.
• Engineers and drivers must choose between intermediate and full-wet tyres under roughly 18 °C track temperatures and 80 percent humidity, which could slow drying.
• Spa’s notoriously changeable Ardennes Forest climate has historically forced mid-race adjustments, making flexible tactical calls essential for the main event.
