The Lowdown
Right, let’s have a look at what’s on offer for Shark Island (Cronulla). This is a reef break that's pretty exposed to the south, and it loves a good SE swell – that’s the optimum direction.
The water temperature is sitting at 63°, which is about 1° cooler than what’s normal for this time of year. Nothing crazy, just a touch of winter still hanging around.
To be honest, the first week is a bit of a write-off. The swell is small, mostly under 3ft, and the wind is constantly messing things up. There’s a bit of a tease on the morning of the 4th of September, with a 3ft south swell and clean conditions from a cross-offshore breeze, but the combined energy is only 181 (moderate), and it’s just not enough to get excited about. After that, we go straight back into a few days of junk.
The real story, the standout, is the morning of Sunday the 6th of September. We’ve got a south swell pushing 5ft with a period of 10 seconds, and the combined energy jumps to 476 (strong). The wind is a gentle cross-offshore out of the south, making it clean. This is the best bet by a long shot. It’s a solid size for this spot, so it’s one for the experienced crew. The break is fairly consistent, so you should get some waves, but it can get crowded here sometimes, so get in early.
Then, later in the window, the morning of Friday the 11th of September looks promising but is a long way out. The forecast shows a 8ft south swell, with a 10-second period, and the energy is a massive 1317 (very strong). The wind is light and cross-on from the NNW, which isn't perfect, but at that size and energy, it’s going to be a big, powerful groundswell. That’s expert-only territory, a real heavy water day for the brave. It’s a long-range call, so keep an eye on it.
So, in short, next Sunday morning the 6th is your best shout. The 11th is a big maybe for the experts.
