Estimate wind force from whitecaps on the water
Estimate wind force on the water by looking at the whitecaps on the waves.
- Time
- ⏱ 5 min
- Difficulty
- ◆ easy
How to do it
- Watch the water surface.
- Read the force from the whitecaps using the Beaufort table.
- Compare your estimate with wind observations on land or on the boat.
Why it works
The Beaufort scale describes the sea state for each force and is a standardised way to estimate wind.
Variations
- At force 7, streaks of foam blowing along the wind direction are a typical sign.
