Why wet weather starts are different

Starting a Formula 1 race in wet conditions is fundamentally different from a dry start. The grip levels are dramatically reduced, visibility is compromised by spray, and the risk of a multi-car incident on the first lap is significantly higher. For these reasons, the FIA has developed specific procedures for wet weather starts.

The three types of wet weather starts

Standing start with wet tires: If conditions are wet but not dangerously so, the race can start normally from the grid on wet or intermediate tires. This is the most exciting option but also the riskiest.

Safety car start: If conditions are too dangerous for a standing start but the race can proceed, the safety car leads the field for several laps. Once conditions improve, the safety car pulls in and the race begins with a rolling start. This is the most common wet weather procedure.

Delayed start: If conditions are too dangerous for any form of start, the race is delayed until conditions improve. This can mean waiting minutes or hours. In extreme cases, the race may be postponed to the following day.

How drivers prepare for wet starts

Wet starts require a completely different approach from dry starts. Drivers must find the right balance between aggression and caution — pushing hard enough to gain positions but not so hard that they lose control on the slippery surface.

The clutch technique is different in the wet. Drivers use less launch RPM to avoid wheel spin, and they must be smooth with their throttle application to avoid breaking traction. The first few corners are the most critical — drivers who can stay clean and build momentum often gain positions that they would not be able to recover later in the race.

Why wet weather starts produce drama

Wet weather starts are among the most dramatic moments in F1 because they combine uncertainty, risk, and opportunity. Drivers who excel in wet conditions — like Senna, Schumacher, and Verstappen — have used wet starts to gain positions that would be impossible in the dry.

In the 2026 era, with lighter cars and less downforce, wet weather starts will be even more challenging. The reduced downforce means less grip in the corners, and the lighter cars will be more nervous under braking. The drivers who master wet weather starts in 2026 will have a significant advantage.
