Fun tomorrow morning for keen surfers down South, much better Friday with a strong increase in W/SW groundswell with favourable winds. Clean and easing Saturday with some stormy new W/SW swell Sunday.

Easing S/SW swell energy, with a strong long-period S/SW groundswell for Saturday, and then some good SW swell mid-late next week.

Southern NSW has retained plenty of size all day so we should be looking at some solid waves for the early session on Tuesday though a gradual easing trend is expected throughout the day.

And this forms the crux for the initial short term forecasting decision - how much size will hold true overnight?
