The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Shark Island (Cronulla) over the next couple of weeks.
First up, the water temp is feeling pretty standard for this time of year, nothing wild to report there. The early part of the outlook is a bit of a struggle, though. From Thursday morning (6th August) right through to the 10th, it’s a real mixed bag of weak, short-period swell and messy winds. The energy is barely getting going, with readings like 81 and 162, and the conditions are just ordinary. Expect a few days of small, average waves before anything decent shows up.
The first real glimmer of hope comes on the morning of Tuesday the 11th. The swell jumps to 6ft from the S with a clean 10-second period, and the combined energy is a solid 712. The wind is cross-off, making it look clean. It’s still a bit marginal, but it’s a step up. Conditions improve through Wednesday and Thursday, but the real standout is shaping up for the weekend.
The best of the bunch is going to be Saturday the 15th. The morning session is looking prime with an 8ft S swell, a light WSW cross-off breeze, and the energy reading is 863 – that’s proper moderate power. It’s going to be clean and punchy. That’s expert territory, not for the faint of heart. The next day, Sunday the 16th, is a serious contender too. The morning sees a 7ft E swell with a very long 11-second period, but the standout is the afternoon: absolutely glassy conditions with an 8ft ESE groundswell and a massive 2277 energy reading. That is excellent, powerful surf for experienced surfers, and the offshore wind makes it a dream.
Monday the 17th is a bit of a beast with 10ft ESE swell, but the cross-onshore wind will chop it up, so it’s more of a challenge than a classic. From Tuesday the 18th into the 20th, the swell drops back a bit, but there are still clean, fun waves on offer, especially on the 18th morning with a 6ft ESE swell and light SSW offshore wind. The 21st Friday morning looks like a solid, clean option too with a 5ft S swell.
Overall, the first week is a write-off, but the second week, particularly that Saturday the 15th and Sunday the 16th, is where you want to be. The break is a fairly consistent reef, and it’s known to get a crowd sometimes, so keep that in mind. The long-period groundswell on Sunday will be lining up nicely on this reef.
Stay stoked, and keep an eye on the forecast.
Rusty.
