Shark Island (Cronulla) Surf Forecast and Surf Report

Alright, Rusty here with a look at what’s coming up for Shark Island (Cronulla).

This reef break, a classic for the advanced crew, is about to fire up, but we’ve got a bit of a quiet start. The forecast kicks off properly on Saturday the 5th, and right out of the gate, we’re looking at a solid, groundswell-driven pulse. The water temp is sitting at 65°, which is pretty much bang on average for this time of year, so nothing unusual there.

Overall Pattern: After a fairly marginal Saturday morning with small 4ft S swell and clean conditions, we see a real build-up. Sunday morning (5th July) brings a serious jump: a 10ft S swell with a 11-second period and a massive combined energy of 2050 – that’s a strong, powerful pulse. Wind is a cross-off from the SSW at 22 mph, which will keep it clean. That’s big, expert-only territory. The afternoon is similar, still big at 10ft from the SSE and a longer 12-second period, energy hitting 2481.

Monday the 6th eases slightly but stays solid with 8ft SSE swell and a 10-second period. The cross-off wind holds, but the energy is still moderate to strong at around 1086.

The Standout: For my money, the best window across the whole run is Wednesday morning, July 8th. We’ve got an 8ft SSE swell with a 10-second period and strong energy (2717 combined), but the key here is the wind: 16 mph offshore from the SSW. That’s glassy, clean surf for an advanced lineup. The rating for that session is excellent for experienced surfers – this is the one to circle. For a reef break like Shark Island, that offshore wind will groom it perfectly.

Another serious pulse arrives later in the run. Sunday morning, July 19th, shows an 12ft SSE swell with a 10-second period, massive energy at 3739, and light 6 mph offshore from the SW. That’s another excellent, clean session for the experienced crew.

Gaps and Lulls: After the 11th, things drop right off. From Sunday the 12th through Monday the 13th, there’s practically nothing – small 1ft to 3ft swells and poor conditions. That’s a quiet 2-day gap. Then Tuesday the 14th sees a rapid return of swell, jumping to 8ft S, building into the 12ft range by the afternoon with clean offshore wind.

Later Period: Into the second week, confidence drops a bit but the trend is solid. Thursday the 16th and Friday the 17th are messy with strong SSW cross-off winds and shorter 8-second periods, keeping the quality poor for paddle surfing. The swell is there (7ft to 8ft), but the wind and short period won’t make for a great wave. This setup might actually be more interesting for kite surfing with that strong, consistent breeze.

Saturday the 18th brings a big, ramping swell: 12ft from the SSE by afternoon with an 11-second period and an enormous 5701 combined energy. That is a huge, powerful groundswell. It’s for experts only. Then Sunday the 19th cleans up beautifully with that light offshore I mentioned.

Crowds: Shark Island can get busy, so be prepared to share the peak, especially on the good days.

So, the headline: Wednesday 8th July morning is the real standout for quality, clean surf. Sunday 19th July morning looks like another cracker. The rest of the run is a mix of big, powerful swells and some lulls.

Stay stoked.
