The Lowdown
Alright folks, Rusty here. Let’s have a look at the 16-day picture for Shark Island (Cronulla).
Right off the bat, the first few days are a bit of a write-off. The surf on offer early on is pretty messy with light cross-shore winds, and the conditions just aren't coming together. We’ve got a long gap of small, poor surf that’s not worth paddling out for. It’s not until Tuesday the 8th that we start seeing something with a bit of shape.
Tuesday the 8th is where we finally get a window. The morning sees a 8ft SSE swell with a solid 9-second period and clean conditions from a cross-off breeze. The combined energy is moderate (860). It's a decent size, pushing past the beginner mark, but manageable. The afternoon drops a touch to 6ft SSE (8 seconds), and the wind goes light, keeping things clean with moderate energy (506). This is a solid option.
Wednesday the 9th is a write-off – strong winds and a 10ft S swell that turns into a cleaning machine, but the wind is too wild for a good paddle.
Thursday the 10th has size – 8ft to 10ft SSE swell – but the wind is fresh and cross-off, so it's lumpy. The combined energy is strong (over 1300), meaning it’s got power, but it's really only for the experts.
Friday the 11th morning still has a 8ft SSE swell from a 9-second period, with moderate energy (904) and cleanish conditions, but again, only for the experienced crew.
Then we hit another lull. From the 12th of September right through to the 16th, the surf quality drops off hard. Small to tiny swells with onshore or cross-onshore winds mean mostly poor conditions. The 16th does show a 5ft S swell in the morning with light wind and a very long 11-second period, giving good shape. The combined energy is moderate (535). This is a nice, clean option for the more advanced surfer, but it’s a one-off in a flat spell.
The standout, without a doubt, is Tuesday the 8th. That morning session has the best balance of size, clean wind, and decent energy. The 8ft SSE swell with a 9-second period and offshore wind will give you some good, reelable waves. After that, it’s a waiting game.
Bottom line: don’t expect much for the first week. The 8th is your best bet for a proper session. The second week has a couple of promising but less certain pulses, but nothing to get too excited about just yet. Crowds are possible here, so get in early.
Rusty.
