How to Read a Wind Barb
wind barbs

A wind barb is a compact means of representing both wind speed and direction graphically.

Each full-barb represents 10 knots (nautical miles per hour), a half-barb 5 knots and a flag 50 knots. Calm conditions are indicated by a dot only. 1 knot is equal to around 1.9km/h.

In the examples to the left the first indicates a 5 knot wind from the south-west, the second a 15 knot wind from the west-north-west, the third a 45 knot easterly and the fourth a 65 knot northerly.
