The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up.
We’re stuck in a bit of a flat spell to start, so don’t bother paddling out just yet. The first real hope doesn’t show up until the morning of Monday the 20th, and even then it’s a slow, small start. The first few days are a write-off, with messy, blown-out conditions and barely any energy.
The real standout for this whole outlook is Shark Island (Cronulla). We’ve got a solid pulse coming through on Sunday the 26th. The morning delivers a clean 7ft south swell with a 10-second period, and the wind is light and cross-off. The combined energy is solid at 939 (moderate to strong), so there’s real push in the water. That afternoon stays clean too, with 6ft south swell and an 11-second period – longer period groundswell, so expect better shaped waves and longer lulls between sets. This is a reef break, so it’ll handle that longer period beautifully. The water temp is sitting around 62°, which is about 1° cooler than average for this time of year – nothing wild, just a bit of a winter chill.
The following Monday morning, the 27th, is also worth a look. Another clean session with 6ft south swell, a long 12-second period, and glassy conditions with a WSW breeze at just 3 mph. Combined energy is still strong at 919. This is expert territory at that size on a reef, but the quality will be there.
Tuesday the 28th starts clean and offshore with a 6ft south swell, good for the more experienced crew. But by the afternoon, the wind picks up and the quality drops.
Overall, don’t waste your time on the first week. Target the 26th through the 28th for the best windows. This is a reef, so crowds are possible – get there early.
Rusty.
