On-shore Beaufort scale.
Beaufort numberEstimated Velocity (m/s)International descriptionObserved conditions
0<1CalmSmoke rises vertically
11Light airDirection of wind shown by smoke drift but not by wind vanes
22Light briseWind felt on face: leaves rustle, vanes move by wind
34Gentle breezeLeaves and small twigs in constant motion; wind extends light flag
47ModerateRaises duct, loose paper; small branches move
510FreshSmall trees in leaf begin to sway; crested wavelets form on inland waters
612StrongLarge branches in motion; whistling heard in telephone wires; umbrellas used with difficulty
715Near galeWhole trees in motion; resistance felt walking against wind
818GaleBreaks, twigs off trees; impedes walking
920Strong galeSlight structural damages occurs
1026StormTrees uprooted; considerable damage
1130Violent stormWidespread damage
