Wind roses which show the frequency of occurrence of wind speed and direction are available on this web site for 81 selected locations around Australia which have a wind record of at least 15 years. Many of these sites have more than twenty five years of data. The wind roses are available for 9am and 3pm for individual months, seasonally and annually. There are also maps available to show average wind velocity across Australia. Wind roses are also freely available within the Monthly climate statistics, while wind roses for other periods and locations may be available by contacting the Bureau of Meteorology (a charge for this service will apply).
