• Smaller into the end of next week with improving winds

Recap

Raggedy 4-5ft surf yesterday , smaller 2ft in the north has been replaced by new S/SW swell today with size to 6-8ft (few bigger ones on the outer reefs) with offshore E’ly winds and smaller 2-3ft surf in the North. 

Plenty of size on the sets with a very S/SW angle

This week and next week (Nov6 - Nov 15)

No great change to the weekend outlook with todays strong S/SW swell slowly easing into tomorrow with 5-6ft sets (few bigger ones on the outer reefs) and smaller 2ft surf in the North. Winds should be offshore E/SE-SE for the early, tending more S/SE-S through the day.

Similar winds for Sun as high pressure slips in under the state and occupies the Bight. Early E’lies tending to S’ly seabreezes. We’ll see surf drop back to 3-4ft between the Capes, 1-2ft in the North on Sun.

Next week is looking subdued but with periods of mostly favourable winds. The gist of it is a band of blocking high pressure and a suppressed zonal storm track. Under current modelling these zonal disturbances in the W’ly track will supply small/mod pulses of SW swell through next week. The high pressure band looks to slip under WA a couple of times next week, leading to a mostly SE flow which should tend more E’ly in the morning. There should be some fun waves about at small wave reefs.

Following zonal fetches to the current fetch (now tracking below Tasmania) hold 3-4ft surf between the Capes into Mon, 1-2ft in Perth/Mandurah with morning E-SE breezes tending S’ly through the day.

A reinforcing SW swell Tues pushes surf heights back to 4-6ft in the SW corner, 2-3ft in the North but winds tend SW as the SW corner gets clipped by a decaying frontal system. 

Wed morning offers better conditions as winds shift E/SE-SE again with leftover sets to 4-5ft, easing during the day.

Thurs and Fri should ease back to 3-4ft in the SW, 1-2ft in the North with E-SE winds for Thurs.

Friday looks trickier to call with GFS suggesting more SE winds while EC has a sharp front clipping the state bringing SW winds.

Winds look to return back to the SE pattern next weekend.

Further ahead and the blocking pattern looks to remain established into the end of next week, suggesting more small swells and offshore winds.

Lets see how it looks Mon and until then, have a great weekend!
