The last couple of months have also been very windy and unsettled with low pressure systems frequently passing near Tassie. The pattern is basically a quick succession of high pressure systems over us, followed by cold fronts and low pressure cells resulting in strong unstable interaction of the different airmasses, with the result of strong winds and storms.
check out the BOM observations for Wilsons Prom and Hogan Island for the last 2-3 months. Cat 1 and 2 hurricane force winds almost every week, with many instances of multiple consecutive days of such weather.
This time of year is also when the temperature contrast between the warm continent and cold oceans is greatest which results in a greater frequency of unsettled weather.
