The Wind Across Australia
is one of the most highly variable meteorological elements, both in
speed and direction. It is influenced by a wide range of factors, from
large scale pressure patterns, to the time of day and the nature of
the surrounding terrain. Because
the wind is highly variable it is often
studied by means of frequency analyses, provided here in the form of wind
, rather than as simple averages.

Wind roses for Australian sites
You can obtain wind roses for locations across Australia from the following:
Information about maximum wind gusts, as well as mean 9am and 3pm wind
speeds, is provided for each available site in the Tables
of Climatic Averages.
Specifying the Wind
|The following points summarise some aspects of wind measurement undertaken
by the Bureau of Meteorology.
The Learn About Meteorology section has an online
calculator to convert between various wind speed units.
- The wind direction is specified relative to true (geographic) north,
and is the direction from which the wind is blowing.
- The direction can be specified either as the number of degrees clockwise
from true north, or as one of the 8 or 16 compass points.
- Wind speeds are 10-minute average wind speeds unless specifically
labelled as gusts, in which case they are an almost instantaneous
- Within Australia, wind speeds are generally presented in kilometres per
- For nautical and aviation use, the wind speed is expressed in knots,
while for some scientific applications, units of metres per second
