Shark Island (Cronulla) Surf Forecast and Surf Report

Right, mate, Rusty here. Let’s have a look at what’s on offer at Shark Island (Cronulla) over the next few weeks. It’s a reef break that’s fairly exposed to a southerly swell, and it needs an offshore from the south-east to really line up. The water temp is sitting right on average for this time of year at 64°, so nothing unusual there.

The start of the period is a bit of a write-off. Wednesday the 9th is a non-starter—big, windy, and messy. Thursday morning the 10th is where it first starts to look interesting. There’s a moderate 7ft south swell with a 9-second period, and the wind is blowing offshore from the SSW at 15 mph. That’s clean, solid surf with moderate energy (861). This is the standout of the whole window. The size is a touch over 5ft, so it’s not for beginners, but for advanced surfers it’s a proper session. Crowds are sometimes a factor here, so keep that in mind.

Friday morning the 11th is still decent. A 5ft south swell, light offshore from the SSW at 6 mph, and the period pushes out to 10 seconds. The energy is moderate (475), and it’s clean. Not as punchy as Thursday, but a good follow-up session.

From Friday afternoon onward, things taper off. The swell drops, the wind goes onshore or cross-shore, and the conditions turn ordinary. Saturday the 12th morning has a 4ft south swell with a 12-second period, which is a bit long for this beachy reef, but the wind is light cross-shore, so it’s marginal. The energy is moderate (464). After that, it’s a long stretch of small, weak, and often blown-out surf. There’s a gap of several days with no real recommendations—from Saturday afternoon right through to the following week.

The next possible window shows up on Tuesday the 16th morning. The swell is small at 3ft from the SSE, with an 8-second period, but the wind goes glassy from the NE at 3 mph. That’s rare and worth noting. The energy is moderate (236), and it’s glassy. It’s not a standout, but if you’re desperate for a paddle and the conditions are calm, it’s a chance.

Thursday the 17th morning has a slight bump with a 4ft south swell, 8-second period, and a cross-off from the WNW at 9 mph. Clean, but the energy is still moderate (204) and the period is short, so it’s not a classic.

Right at the end of the forecast, on Thursday the 24th afternoon, there’s a big pulse of 8ft south swell with a 7-second period, but the wind is screaming cross-off from the south at 25 mph. That’s a strong breeze, and the energy is strong (817), but it’s a brutal, messy, stormy setup. That’s more for kite surfers than paddle surfers, and the scores reflect that—it’s poor quality.

So, if you’re planning a surf, Thursday the 10th morning is the clear winner. The rest of the week is a slow grind with small, weak swells, and the long-range stuff is unreliable. Keep an eye on the glassy morning of the 16th for a quiet, clean session if you’re not fussy about size.

Rusty.
