Alright surfers, Rusty here with a look at what’s coming our way for Shark Island (Cronulla). We’ve got a bit of a slow start, but there’s some serious power lined up for the patient ones.

First up, the water temp is sitting at a pretty normal 65° for this time of year, so nothing unusual there.

Right now, and for the next couple of days, it’s flat as a tack. We’re looking at tiny 1 ft to 3 ft swells from the NE and S, with weak energy. The winds are cross or cross-off, but honestly, there’s just nothing to work with. Don’t bother paddling out until Sunday.

Sunday the 5th is where the curtain lifts. A solid 10 ft S swell rolls in with a period of 11 seconds and a heap of energy. The morning has a fresh 30 km/h SSW offshore blowing, which will clean things right up. This is a proper groundswell, and for a reef like Shark Island, that’s a good thing. However, at 10 ft, this is expert territory only. Keep that in mind.

The swell hangs in through Monday and Tuesday at 7 ft to 8 ft, still a good SSE/SE direction. The standout window looks like Tuesday morning the 7th and Wednesday morning the 8th. Tuesday brings 7 ft of SSE swell (period 10s) with a light SW offshore, making for very good conditions. Wednesday morning is even cleaner with a light 10 km/h SW offshore and a 7 ft SE swell. Both mornings are calling for clean, lined-up waves.

After a bit of a trough, we get another pulse on Thursday the 9th (8 ft S) but with a moderate cross-off wind. It’s still rideable.

Then there’s a quiet spell from Friday the 10th through Tuesday the 15th. A small 3 ft to 4 ft swell is on offer with light winds, but it’s nothing to write home about.

Here’s the real gold: Wednesday the 15th morning is looking like a sleeper hit. A 7 ft S swell with a 11-second period and a light WNW cross-off. Clean and punchy. That morning is a standout.

But the big daddy arrives Thursday the 16th. We’re talking an 12 ft SSE swell with a *very long* 13-second period. The energy is massive. Morning has a gentle 15 km/h W cross-off, and by the afternoon it’s even cleaner with a light SSE cross-off. This is excellent, powerful surf for experienced surfers. If you’ve got the skill, this is your session. The long period means it’ll be holding up well on the reef.

Into the final weekend, Saturday the 18th morning brings a massive 15 ft S swell. That’s a beast, period at 11 seconds. With a cross-off wind it’s clean, but this is for experts only, and will be very heavy. After that, the trends fade off.

Best on offer? Tuesday 7th morning for a solid, manageable swell with clean offshore wind, and Thursday 16th morning for the big, clean groundswell that the Shark Island reef will turn into something special. That Thursday is the one to circle.

Stay safe out there.
Rusty.
