In other words it’s a winter storm.
The result is high winds and torrential rain causing flooding and infrastructure damage.
In the last few days we were under a severe weather warning due to one of these.
As it turned out it was not as bad, for us anyway, as predicted.
The high winds however have caused huge waves to develop. Some as high as 10m (33 ft) have been recorded. Obviously for people living along the beaches it is a concern as erosion is always a problem.
How are these wave heights recorded?
The government has a series of seven waverider buoys moored at depths of between 70 and 100 meters at a distance of 6 to 22 km off the 1200km coastline.
There is one off the coast of Batemans Bay near us.
They record wave height, wave period and wave direction and send the data on an hourly basis to stations on shore.
The Bureau of Meteorology and the State Emergency Services then use the data to issue marine warnings and inform its responses to coastal storms.
We know the surf is big when we can hear it at our place.
And this is one of those times.
Even in Sydney Harbour they had to cancel the Manly ferry because of the wave action. Its route from the CBD (downtown) to Manly crosses the open sea at The Heads.
I bet the surfers are champing at the big to get out to all the well known big wave sites over the next few days.
It was too wild to venture out at our beach today. See video below
There should be some spectacular photos and videos to come *
