Beaufort Wind Scale for Paraglider Pilots
Here is a wind chart which will help you estimate wind speed by observing effects the wind is having on your surroundings. If you refer to this chart as you observe the wind over time you’ll learn to judge the wind more accurately.
Wind effects on land and water.
Wind sock appearance
Smoke rises vertically. No movement in leaves. Windsock hangs limp. Water surface smooth and mirror-like.
1 – 3 mph
Wind direction shown by smoke drift. Minor movement of windsock. Scaly ripples on water no white caps.
4 – 7 mph
Wind felt on face, leaves rustle, smoke leans. Small wavelets, crests have a glassy appearance but do not break.
8 – 12 mph
Leaves and small twigs in constant motion. Smoke leans and 45 angle. Large wavelets small scattered white caps.
13 – 18 mph
Raises dust, small branches moved. Smoke leans 30 from horizon. Small waves becoming longer, frequent white caps.
18 – 24 mph
