Surf-wise the fetch off the top of the high and a broad troughy area, holds another round of E’ly quadrant swell in the 2-3ft range, very similar to the last round. Quality will be wind affected but we should see light enough winds in the morning for glassy lightly wind affected surf.

Not a great deal of change since Mon with a slow moving, weakening high in the Tasman, and a coastal trough off the QLD Coast (responsible for hundreds of mm of rainfall) now moving away and dissipating. A trough moving north from a position east of Tasmania brings a renewal of the S’ly pattern into Fri before the summer pattern slowly resets over the weekend.
We’ve got a moderate strength high pressure cell (1025hPa) in the Tasman, connected to a high pressure belt under the continent, directing NE winds in Central/Southern NSW, more E-SE in the sub-tropics where a broad troughy area is directing a stronger onshore flow and whipping up local swells from that direction.
No great change to the weekend f/cast. Just a small, weak mixed bag of leftover S swells and E swells to 1-2ft at best Sat, similar or smaller Sun.
Elsewhere, it’s a bland pattern with a dormant Coral Sea. Cold fronts later this week and over the weekend will supply some minor S swell favouring NENSW S facing beaches.
For our sub-tropical region the main swell source will be a proximate N’ly fetch extending up to water adjacent to the CQ coast and holding a workable NE windswell.
An approaching inland trough will freshen northerlies about most coasts on Sunday, so make the most of Saturday.
We’ve got building trade swells for the next few days, and a weakening synoptic pattern in the north, that will result in light variable winds and sea breezes in most northern areas.
I like the look of these weather charts.
Wednesday is where we’ll start to see a gradual increase in new trade swell from a broad easterly fetch developing from this weekend onwards.
