Recap

Small NE swells to 1-2ft on Sat, decreasing further to 1-1.5ft on Sun. Today is seeing some minor E swell to 2ft with light/variable winds before S/SW winds kicked up. 

This week and next week (Apr 28- May 9)

Another dynamic autumn week beckons with a current low in the Tasman slowly drifting E while a dominant high moves into the Bight. We’ll see another front and trough develop tomorrow on the leading edge of the dominant high, which sees S swell short term then a strong S/SE-SE fetch develop through the lower Tasman from mid week. Plenty of swell from this source seeing fresh S’lies, easing later in the week.

In the short run, we’ll see fresh/strong S’lies develop and a strong spike in short range S swell to 4-5ft at S exposed breaks. 

Those S’lies hold into Wed with a mix of S-S/SE swells to 3-4ft, easing a notch during the day. 

S’ly winds will start to ease Thurs as high pressure moves over the Island, so expect light winds, tending to variable and even light W’ly breezes through the a’noon. Should be some fun 2-3ft waves from the SE-E/SE through the day. 

Fri looks to see continued light offshore winds, tending to variable seabreezes with some fun E/SE-E’ly surf from fetches near New Zealand in the 2-3ft range.

Into the weekend and we should get another fun pulse of E’ly swell from a fetch near the North Island to 2-3ft with offshore winds.

Easing swells into Sun with NW winds.

Not much on the radar for most of next week. We’ll see a dominant high moving over New Zealand early next week, becoming flat-topped and establishing a long, broad E’ly flow through the South Pacific slot and into the Coral Sea. 

That will favour the sub-tropics to temperate NSW but we may see some small E/NE swell start to filter down to Tasmania by the end of next week.

Otherwise tiny with the southern swell window effectively blocked.

Check back Wed for latest updates.

Seeya then!
