Shark Island (Cronulla) Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll be straight with you—this stretch for Shark Island (Cronulla) is a tough one. We’ve got a long, frustrating run of small, wind-affected, or just plain ugly surf coming up. The first real day with anything on offer doesn’t show up until Sunday, September 6th, so we’re staring down a week of flat-to-poor conditions before we see a glimmer of hope. For a spot that’s fairly exposed and a consistent reef, this is a quiet spell.

For the first week, it’s a write-off. Monday the 31st of August kicks off with a tiny 3 ft south swell, but it’s getting slapped by a cross wind, so it’s choppy and messy. The combined swell energy is a weak 204—barely a pulse. Tuesday and Wednesday are even smaller and still cross-onshore, with energy dropping to 122 on Wednesday morning. The water’s sitting at 63°, which is about 1° cooler than average, so it’s a bit chilly but nothing wild. Thursday brings some offshore wind on a 2 ft south swell, but that’s just too small to get excited about. Friday the 4th of September shows a slight bump to 3 ft with a 12-second period, giving a bit of energy (291), but it’s cross-shore and messy again. Honestly, it’s all poor.

Then, finally, on Sunday the 6th of September, we get our standout. A 5 ft south swell rolls in, and the wind goes glassy in the morning—zero wind. This is the best window of the entire forecast. The combined swell energy jumps to 421, so there’s some proper push. The swell is coming from the south, which is pretty close to its optimum southeast direction, so it should set up nicely over the reef. It’s not huge, but with clean, glassy conditions, the waves will be lined up and user-friendly for the advanced crew this break is for. That Sunday morning is the one to circle. The only catch? Crowds are possible here—it’s a well-known reef and word will get out.

After that glory window, it’s back to average. Monday the 7th gets onshore and drops back to 2 ft. The rest of the second week sees pulses of bigger swell—up to 8 ft on Saturday the 12th—but the wind is howling from the south at 35 km/h or stronger, with energy spiking to 1113, which is strong. That big swell is only for experts if you’re game, but with that wind, it’s more of a blown-out mess. On Tuesday the 15th, we get another glassy morning on a tiny 3 ft south swell, but that’s more of a grovel session than anything special.

So, bottom line: the whole 16-day run is a drought until Sunday morning, September 6th. That’s your mark. Glassy, clean, a bit of size. Everything else is either too small, too windy, or too far off. Hang in there.
