The data is logged at two minute intervals, but there is data recorded every minute. On the graph, the Blue line represents the average windspeed, the Red line is the maximum gust for that interval, and the Green line is what the wind has dropped off to in the same interval. Fuschia is the Barometer, and the dew point and Blue is humidity.
