Shark Island (Cronulla) Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll be straight with ya – the next 16 days are a bit of a mixed bag for Shark Island (Cronulla). We’ve got a real slow start, then a brief pulse of swell mid-week, followed by a long quiet spell. The water temp is sitting at 64°F, which is about average for this time of year, so no surprises there.

The first few days, Monday through Tuesday, are flat. We’re talking tiny scraps of 0.3ft to 1.0ft from the south with a long 11-second period, but the combined energy is a measly 6 to 26 – barely a ripple. Winds are cross-off, but there’s just nothing to work with. A total write-off.

Then Wednesday the 15th, things start to wake up. The swell jumps to 7ft from the south with a 10-second period, and the combined energy hits a solid 1268 – that’s proper moderate to strong energy. The wind is a cross-off 12 mph from the SSW, keeping it clean. This is the standout window. The morning is marginal, but the afternoon builds to 7ft (energy 1468) and a score of 3/10. It’s a reef break, so that long period groundswell (10 seconds) will shape up nicely, but at this size – over 5ft – it’s getting into expert territory. Keep in mind it’s a fairly consistent spot, but crowds can show up sometimes, so be ready for company.

Thursday the 16th holds some size, but the quality drops. Morning sees 7ft from the south, but the period has shortened to 8 seconds, and the wind is a fresh 19 mph cross-off – still clean, but that short period makes it lumpy. The combined energy is 1058, but scores are a 1/10. By afternoon, the swell drops to 6ft, wind picks up to 22 mph, and conditions go poor. Not worth it.

From Friday the 17th onward, it’s a long, slow grind. The swell fades to tiny 1.0ft to 4ft, with combined energy mostly under 339. The best chance for a surf comes Sunday the 19th morning: 4ft from the east, 9-second period, and glassy winds from the ENE at 3 mph. That’s a rare treat – clean, small, and surfable, with a combined energy of 339. It’s a 2/10 score, but for the conditions, it’s the pick of the second week. The rest of the week is plagued by onshore winds, small swell, and poor surf. There’s a gap of about 5 days with no real recommendations after the 21st, with only a few 2ft to 3ft days that are just ordinary.

So, to wrap it up: your best bet is Wednesday the 15th afternoon for the biggest, most powerful swell, but it’s for experts only. If you’re after something more mellow, Sunday the 19th morning with glassy conditions is your go-to for a clean, small session. The rest is a waiting game.

Rusty.
