A classic Summer blocking pattern is now setting up, with a slow moving high drifting well south of Victoria and a series of troughs interacting with a strong high pressure ridge which has reached Central NSW and is now building into more sub-tropical regions.

It's not a healthy looking forecast with limited swell energy though with favourable winds for the exposed beaches.

A new mix of swells are due from tomorrow but with initially average winds, improving on the backside.

With high pressure parking itself beside Tasmania for most of this week we’re expecting a period of tiny surf to become established through Thurs into the weekend and early next week, with swell sources effectively blocked by the large high .
