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.

Wave Height, Wave Period, and Wave Direction

shown in the legend.
The wave period indicates the time (in seconds) between successive waves. Wave period lines indicate areas

Wave directions appear on the chart using red arrows. The direction of each arrow pointer indicates the
direction in which a wave is moving.
