The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming up for Shark Island (Cronulla).
Right now, we’ve got a bit of a slow start. There’s no real worthwhile surf on offer for the first few days. We’re looking at a gap of a couple of days with nothing to get excited about. Friday the 28th has some morning swell at 5ft from the SSE, but the wind is going to be a problem later, and it’s not really a standout anyway. The water temp is sitting at 63°, which is just about average for this time of year.
The first real chance of something decent shows up on Monday the 8th of September. This is the one to circle. The early morning has a solid 8ft swell from the south, with a long period of 14 seconds. That’s groundswell energy with plenty of punch – the combined energy is a strong 3323. The wind is offshore from the SW at just 9 mph, making for clean, lined-up waves. This is big, powerful surf – over 8ft means it’s only for experienced surfers. This is a reef break and it’s fairly consistent, so if you’ve got the skill, the morning of the 8th is your best bet. Crowds can show up here sometimes, but for a setup this good, it’s worth the company.
The swell hangs in there on Wednesday the 9th, with 7ft to 8ft from the south, still with good period (12 seconds) and moderate energy (1785 to 2117). The wind is cross-off, so it will be clean. It’s big, but it’s a step down from Monday. Still, a very good option for the experienced crew.
After that, it fades quickly. The rest of the week into the second week shows dropping swell and poor conditions, with nothing else to recommend. The 16-day window gives us one clear standout, and that’s the morning of September 8th. Get on it.
