Wind rose plot


Wind rose plots show what percentage of wind cam from what direction in a given place. The one in this example shows the wind direction in Olympia, Washington. About 18% of the wind came from the south. This wind rose also shows the percentage of strength that the wind came in from each direction. For example, 11% of the total wind in Olympia came from the north and 2% of the total wind in Olympia came in from the north between 11-17 knots.
