The seasonal breakdown of winds shows that the predominant southeast to southwest winds are lighter and most
frequent during the cooler autumn and winter months. Summer, and to a lesser extent spring, are characterised by
stronger winds and an increase in frequency from the north-northwest to east direction.

The diurnal breakdown of winds shows that the strongest winds are predicted during the afternoon (midday to 6pm)
when winds are predominantly from the north-northeast to south-southeast. During the evening (6pm to midnight)
winds are lighter and from the southeast to southwest and from the north-northwest to north-northeast. Winds drop
in strength during the night (midnight to 6am) and increase in frequency direct from the south-southwest. Morning
winds (*6am to midday) show the transition through to afternoon winds, increasing in strength as well as in the
frequency from the southeast.
