Shark Island (Cronulla) Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about Shark Island (Cronulla). It’s a reef break that takes a fair bit of south-east swell, and over the next couple of weeks, we’ve got a mixed bag coming. Water temp is sitting at 65°, which is pretty normal for this time of year – nothing wild going on there.

Right now, it’s flat. Friday morning, there’s basically nothing doing with a tiny 2ft north-east windswell and a moderate west-northwest breeze blowing cross-off. Not worth paddling out. Friday arvo is even smaller. We’ve got a few days of small, poor surf to start with.

Saturday morning the 4th, the swell turns on a bit – 3ft from the south with a long 12-second period. That long period means better shape but longer waits between sets. The wind is light and cross-off, which is clean, but the overall energy is moderate (288). It’s borderline, maybe a tide issue, but it’s the first thing that looks rideable.

Sunday morning the 5th is where things get interesting. We’ve got a solid 10ft south swell, 10-second period, and fresh offshore wind from the south-southwest. The combined energy is pumping at 1666 – that’s strong. This is a big swell, over 8ft, so it’s only for the experienced crew. The direction matches what this place likes, and offshore wind will make it clean. Sunday arvo holds similar size but with a bit more south-east in the swell and cross-off wind – still big, still only for experts.

Monday the 6th stays big, around 8ft from the south-southeast, but the wind turns cross-off and it’s a bit messy – moderate energy at around 1064. Not the pick.

Tuesday the 7th morning – this is a standout. You’ve got 7ft south-southwest swell, offshore wind, clean conditions. The energy is strong at 1023. The swell direction is about as good as it gets for Shark Island, and that offshore flow will have it looking fun. It’s still a big wave but a notch below Sunday. Tuesday afternoon holds size but the wind swings cross-off.

Wednesday the 8th morning offers 7ft from the southeast with very light west wind – clean, but it’s a touch smaller. Still a decent session if you’re keen.

Thursday the 9th drops to 5ft from the southeast, light offshore wind – clean and more manageable. Not a standout but a nice smaller day.

Friday the 10th morning has 4ft, 9-second south-east swell, gentle offshore breeze – clean and cruisy.

From there it fades. Saturday the 11th has tiny 3ft surf, glassy conditions in the arvo but very weak energy (81). Sunday the 12th is flat. Monday the 13th sees a new pulse – 5ft south swell, cross-off wind, but nothing special.

Tuesday the 14th gets messy with strong wind and dropping size. Wednesday the 15th through Friday the 17th is a write-off – tiny swell, strong winds, poor conditions.

Then, hold onto your board… Saturday the 18th morning. This is the real standout. 12ft south swell, 11-second period, light offshore west-northwest wind. The combined energy is monstrous at 2718. This is a very strong, very long-period groundswell hitting the reef perfectly. It’s over 8ft so experts only. The direction is ideal for Shark Island, and light offshore wind will have it glassy. This is the one to circle on the calendar – looks incredible but it’s two weeks out, so keep an eye on it.

The swell sticks around Saturday arvo at 13ft from the south-southeast, but wind goes cross-on and it’ll be harder to get into.

So the two standouts? Sunday the 5th for a big, raw south swell with offshore wind, and Saturday the 18th for a massive, clean groundswell with perfect conditions.

Cheers,
Rusty
