The Lowdown
Alright, let’s get into it. Rusty here.
First up, we’re looking at Shark Island (Cronulla). This is a reef setup, so there’s a bit of a wait for the good stuff. The swell and wind are not lining up for a while, but when they do, it’s going to be solid.
The water temperature is about average for this time of year, nothing unusual to report.
The first real opportunity surfaces on Thursday, August 27, during the morning. You’ll see a clean 6ft swell from the south, with a period of 9 seconds. The wind is a gentle cross-off, so the wave faces will be tidy. The combined swell energy is solid (597), so there’s a decent amount of push. It’s a good option for the advanced crew, but it’s not the standout.
The real standout is Saturday, August 29, in the morning. This is where it gets exciting. The swell is 7ft from the south, period 9 seconds, and the wind is a light breeze swinging cross-off. The energy is pumping (1355), and the conditions are described as excellent for experienced surfers. This is a proper session for the experts. The break is fairly consistent, and crowds are only sometimes an issue, so you might get a few waves to yourself if you’re early. The swell direction (S) is a good match for the optimum (SE), so it’ll be lining up well on the reef. This is the best on offer in the whole window.
After that, Sunday morning, August 30, serves up a glassy 4ft south swell, but it’s only ordinary. The energy is low (265), so it’s not worth making a big deal of.
Then we hit a dry spell. From Monday, August 31, all the way through to Saturday, September 5, the surf is poor. Tiny waves, wrong winds, and very low energy. It’s a real gap of about a week with nothing to chase.
Things start to look interesting again further out. On Thursday, September 10, in the morning, we see an 8ft south swell with a period of 8 seconds. The wind is a moderate offshore from the WSW, and the energy is pumping (717). This is a serious swell, and it’s over 8ft, so it’s strictly for experts. It’s a long-range call, so keep an eye on it, but it’s promising.
All in all, the clear winner is Saturday morning, August 29. Get out there early for the best of it.
Rusty.
