No major change to the weekend outlook, though Sunday’s winds are looking a little fruity.

A broad trough stretching the length of the NSW coast will form a surface low well east of Eden early Thursday, enhancing an already-strong S/SE flow through our immediate southern swell window.
Lots of synoptic activity on the cards this week but ultimately just a few small windows of opportunity until the weekend when we'll see the dynamics change.
The key to scoring good surf will be to identify the timing of the wind change, as we should see westerlies somewhere in the middle.
Easing southerly swells will dominate tomorrow, and we’ll also see a small level of local NE windswell thanks to this afternoon’s developing breeze.
From about lunchtime onwards (South Coast) and late afternoon across the Sydney region, we'll be on high alert for the leading edge of a decent long period southerly groundswell.
TC Jasper is set to take a W’ly track with a Far North QLD coastal crossing now the most likely outcome and thus no real surf potential for temperate NSW.
TC Jasper has formed in water surrounding the Solomon Islands and is intensifying under favourable conditions. Most models now are suggesting a SW-W curvature as it enters the Coral Sea, with a limited surf potential compared to Mondays notes, especially for temperate NSW.
Weak high pressure in the Tasman and a trough is creating a “doldrums” type pattern of slack pressure gradients and small swells this week, with a few wind changes to negotiate. No major swells expected this week. The headline feature is a potential major tropical cyclone drifting into the Coral Sea with a poleward (southwards) track late this week, over the weekend and into next week.
Low pressure has moved off the coast and is slow moving, with a broad fetch of strong E’ly winds on the southern flank of the low supplying plenty of E-E/SE swell to Southern NSW (and Tasmania).
