Windrose maps are maps that measure the speed and direction of wind in particular areas. Using a grid, the frequency of wind over time is measured and put onto the graph. In this map, the different colors show the difference in wind speed. The red shows the largest amount of wind speed with 11-17 knots, and the yellow area shows the lowest amount of wind speed with only 1-4 knots. Also shown in this map is the direction of the wind as well. In this map, there is more wind on the west side than there is on the east side.
