The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for Shark Island at Cronulla. It’s a bit of a mixed bag, but we’ve got a couple of windows that are worth paddling out for.
For the next few days, it’s pretty ordinary. The wind is messy and the swell is small and weak. We’ve got a bit of a wait ahead of us. The first real glimmer of hope shows up on the Thursday morning of the 13th of August. That’s when we see a clean 5ft S swell rolling in with a gentle offshore wind from the SW. The water temp is sitting at 61°F, which is a bit colder than normal for this time of year, so you’ll want a good wetsuit. The combined energy is moderate (325), and it’s a reef break that’s fairly exposed to the S swell, matching the optimum direction. This is the standout of the whole forecast—clean, lined-up waves for the advanced crew. Get on it.
The Friday morning of the 14th of August is worth a mention too. The swell drops a little to 4ft from the S, but you’ve got near-glass with a light offshore SW breeze. The energy is still moderate (292), and conditions look clean. Not as punchy as Thursday, but a solid backup session.
After that, things get skinny again. A few tiny pulses come through, but the wind gets messy or the swell is too small. There’s a long gap from the 15th through to the end of the window with very little to get excited about. The swell is mostly under 3ft, weak, and the wind is often cross or cross-off, leaving the surf poor and uninviting. The energy levels drop right off, with many readings below 100 (weak) and some as low as 21 (very weak). It’s a quiet end to the outlook.
So, to sum it up: your best bet is the Thursday morning of the 13th, with Friday morning the 14th as a solid backup. After that, it’s a waiting game. Stay tuned.
Rusty.
