Shark Island (Cronulla) Surf Forecast and Surf Report

G'day, I'm Rusty. Let's get straight into what's cooking for Shark Island (Cronulla). This is a proper reef break, advanced only, and it's fairly exposed to the swell. It's a spot that demands respect, no room for beginners.

Right now, Thursday morning, we've got a solid 6ft swell from the SE, with a 10-second period, and the combined energy is pumping at 829 (moderate). That's a decent amount of push. The water temp is sitting at 63°, which is pretty normal for this time of year, nothing unusual. We've got a light S cross-off breeze at 9 mph, keeping things clean. This is looking like the best on offer for the early part of the outlook. The swell direction matches the optimum, and the conditions are set for a good session. This is your standout.

Thursday afternoon, the swell holds at 6ft, but the energy drops a bit to 599 (moderate), and the forecast gets a bit more questionable. Still, a clean wave with a cross-off breeze.

Friday morning rolls in with a 6ft swell from the SE, period at 9 seconds, energy at 513 (moderate). The wind is cross-off from the S again, so it's still clean. Friday afternoon sees the swell dropping to 5ft, period back to 10 seconds, and a lighter SSE breeze at 6 mph. Solid, clean, consistent surf.

Saturday morning, the swell drops to 4ft, and the wind swings to a cross-shore from the NW at 9 mph, bringing a bit of chop. Not your best bet. The swell drops further through the weekend, and by Sunday, we're looking at tiny 2ft waves with a strong W wind. The energy is a weak 91. It's a dead period. This flat spell stretches from the weekend right through the middle of the following week, with swell heights barely above 1ft until Wednesday.

Now, here's where it gets interesting but also messy. From Wednesday the 15th of July, the wind really cranks up. A big S swell starts building, but it's accompanied by a howling S wind at 28 to 31 mph. The swell jumps to 10ft on Wednesday, but the energy is 1062 (strong wave energy). The problem is the wind is so strong it's gonna be a battle. This is looking more like a kite-surfing setup than a paddle session. Thursday the 16th sees the swell absolutely detonate at 16ft from the SSE, with a monster energy of 5494 (very strong wave energy). The wind is still screaming from the SSE. This is for experts only, and even then, it's a risk. The period is 10 seconds, so it's a bit short-period for a groundswell, but the sheer size is the story.

This big, messy swell continues through the 17th and 18th of July, with 15ft to 16ft swells, and cross-shore winds from the SE creating lumpy conditions. The energy readings are massive (4725 to 6518), but the quality is poor for a clean paddle.

Finally, on Sunday the 19th of July, the wind finally drops. The morning has a 10ft swell from the SE with a longer 11-second period, and a light S cross-off breeze. The energy is 2591 (strong wave energy). The afternoon is the real standout for the second half of the outlook. The swell holds at 10ft, still from the SE, period at 11 seconds, and the wind is a gentle SSE cross-off, making it clean. The combined energy is 1867 (strong wave energy). This is a solid, powerful groundswell with clean conditions for experienced surfers. This is your second prime window.

Monday the 20th sees the swell drop back to 6ft, and the wind goes light from the NW, but it's a cross-shore, so it's not perfect. The energy is a more moderate 812. After that, the swell fades away again, with a few smaller pulses on the 22nd and 23rd, but those come with strong winds again. The very last day of the outlook, Friday the 24th of July, looks promising. We've got a 7ft swell from the ESE, an 11-second period, and a light WNW cross-off wind. The energy is 1043 (moderate wave energy). This is a clean, glassy option for the afternoon.

In summary, your best bets are the clean, consistent SE swell on Thursday morning the 9th and Friday the 10th, and then the big, powerful, but clean conditions on Sunday afternoon the 19th of July. The middle of the outlook is a write-off or a battle with the wind. Remember, this is an advanced reef break, and when it's big, it's for experts only.

Rusty.
