Surface Winds

Surface wind vectors appear on the Sea Conditions chart using wind barbs that indicate the direction from
which the wind is blowing. A wind barb is a circle with a tail. The line or flag attached to the tail of the wind barb
indicates the wind speed. A short line represents 5 knots, a long line represents 10 knots, and triangle
represents 50 knots.
