Wind Roses
Wind roses are an information packed plot providing frequencies of wind direction and wind speed. A wind rose can quickly indicate the dominant wind directions and the direction of strongest wind speeds. The IEM has generated these wind roses based on our archive. The archive does contain errors and non representative data, so please use care when using these plots. In general, data from the airports is of good quality and representative of the local surrounding area.
