Shark Island (Cronulla) Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s on the menu for Shark Island. Straight off the bat, the next week and a half is pretty grim – a long, flat, blown-out run with nothing really worth paddling out for. A lot of weak energy, wrong winds, and tiny junky waves. But hang in there, because the back half of the window starts to look proper interesting.

Looking at the first block, from Sunday the 2nd right through to around Saturday the 15th, it’s a real write-off. The swell is tiny, mostly under 3 ft, with a combined energy reading often below 100 – that’s weak, gutless stuff. Winds are mostly on, cross-on, or just messy, and the score is consistently a zero. There’s a brief glimpse of something on Thursday the 6th morning with a 4 ft S swell and clean conditions at 223 (moderate energy). Still ordinary. Then we hit a long stretch of nothing.

The real standout comes in the second week. The action kicks off on Saturday the 15th afternoon. We’ve got a 6 ft S swell rolling in, period at 12 seconds – that’s a proper groundswell – and energy is pumping at 879 (strong). Winds are clean and cross-off. This is a legit window.

But the absolute best of the whole 16-day run looks to be Sunday the 16th morning. Shark Island (Cronulla) is set to fire. A 6 ft S groundswell, with a period of 13 seconds and a huge combined energy of 971. Winds are light, cross-off side, so it should be clean and lined up. This is the one to circle on your calendar.

Monday the 17th morning stays solid with a 5 ft S swell, a long 14-second period, energy at 1046 (very strong), and offshore cross-off winds. That is a serious session in the making.

Water temp is sitting around 62°, about 2° colder than normal for this time of year, so a bit of a chill on the bones, but with that kind of surf, you won’t notice.

Just a heads up: Shark Island is a shallow reef, so when that long-period S swell hits with that much energy, it’s gonna be powerful and a bit shifty – definitely one for the advanced crew. Beginners should sit this one out, especially when it gets over 5 ft. Crowds are a possibility here, especially with conditions this good, but it’s worth the fight.

For the first week, honestly, it’s a kite-surfing kind of setup – strong winds, small messy waves and blown-out conditions. But for paddle surfing, wait for that period from the 15th onwards.

Rusty.
