Recap

Tiny surf yesterday with clean conditions, today has seen a strong cold front pass the state and new S swell to 3-4ft at S facing beaches under fresh W’ly winds.

This week and next week (Apr24- May3)

The sharp trough in low pressure moving NE of Tasmania is generating a fetch of gales tracking through the southern swell window, with a following long, broad fetch of S’ly biased winds moving NE through tomorrow, setting up a series of S pulses in the run up to and over the weekend. A monster high (1037hPa) moves into the Bight tomorrow and slowly weakens as it enters the Tasman on the weekend, bringing light winds before more frontal activity next week brings overlapping S swell pulses.

In the short run we’ll see fresh SW winds tomorrow as a strong following front passes to the SE of Tasmania. Todays pulse eases off but we should see new S swell fill into the 3-4ft range tomorrow, building further into Fri into the 5-6ft range at S facing beaches with offshore W’ly winds tending variable in the a’noon.

No great change to the weekend f/cast. S swell leftovers to 3ft at S facing beaches, easing during the day. We’ll see winds swing NW again as high pressure moves north of Tasmania and a pre-frontal trough sits below the state.

Tiny surf Sun with NW pre-frontal winds. Tiny surf then extends into Mon.

By Tues we should see a new pattern develop as a robust front and trough looks to bring a robust SW’ly change with an increase in mostly short range S swell. Expect windy S swell to 3-4ft on Tues.

Windy S swells continue into Wed as another major high well south of the Bight shifts E and a series of fronts sweeps across the lower Tasman. That should see moderate to sizey S swells through the second half of next week with an onshore SW-S flow due to the southwards positioning of the dominant high pressure ridge.
