The Lowdown
G'day, I'm Rusty. Let's get into it.
Alright, look, we've got a bit of a tough stretch ahead for Shark Island (Cronulla). This is a solid reef setup that's fairly exposed, and it loves a swell from the SE, which is its optimum direction. The water's sitting at 62°F, which is normal for this time of year.
Right now, it's pretty quiet. From Monday the 24th right through to the end of August, there's just nothing doing. The swell is small, mostly under 3ft, and when it does show, the wind is messy - cross-onshore, onshore, or just plain poor. The combined energy is weak, hanging around 100 to 200, which is just not enough to get this place firing. The best you'll see is a few clean-looking mornings but with next to no swell.
There's a small window of hope on Thursday the 27th morning. The swell is 5ft from the S, period 8 seconds, with a clean cross-off breeze. The combined energy bumps up to 358 (moderate), so it's surfable, but the conditions are very ordinary. It's a "maybe" at best.
Then we hit a long dry spell. Friday the 28th through to Sunday the 7th of September is a desert. Swell drops to knee-high, winds are all over the shop, and the energy is weak. Don't bother.
Now, here's the one that might get your attention. On Tuesday the 8th of September, we see a proper pulse. The morning shows 6ft from the S, period 10 seconds, with a strong 19 mph cross-off wind from the WSW. The combined energy jumps to 727 (strong). This is a big, powerful swell, but it's only for experts due to the size. The wind is clean, so the surface will be good, but this is a serious swell for Shark Island. It's a standout, but it's a long way off and the forecast is less certain. The afternoon drops to 5ft.
So, the call is simple: save your energy for that Tuesday the 8th of September morning. It's the only real standout in the whole 16 days. Anything before that is a write-off.
Rusty.
