How to Read

Each petal shows wind from that compass direction. Petal length = % of all observations from that direction (e.g. a long NE petal means wind frequently blows from the northeast).

Petal color bands stack speed classes from center (light) to edge (strong). All 16 directions + calm = 100% of observations.

Center gray circle = calm (<1 kt, no direction).

Hover a petal to see the speed breakdown within that direction.
