The Lowdown
Alright, Rusty here again. Let’s talk about Shark Island (Cronulla) in feet and degrees. The water’s at 63°F, which is pretty much average for the season – nothing to complain about.
First real surf pops up on Wednesday, July 15, early. It’s a clean 8ft south swell with a 10-second period, and a stiff SSW offshore wind at 12 mph. The combined energy is 2283, so there’s a lot of push. This is a heavy reef wave, only for the experts. The swell hits from the south, close to the optimum southeast, so it’ll hold its shape. It’s a real standout but short-lived – by afternoon it drops to 6ft and the wind goes cross-off, getting messy.
Then we hit a dry spell from Thursday through Sunday, with small, weak swells and choppy winds. Nothing worth chasing. That’s a four-day break with no good options.
The next decent chance is Monday, July 20, afternoon. The swell is 5ft from the ENE with a 10-second period, and the wind goes glassy – NE at 3 mph. The combined energy is 572, moderate but clean. It’s a fun, quiet session if you’re around.
The big one comes on Thursday, July 23. Early morning, clear skies, light offshore wind from the SW at 6 mph, and a 6ft east swell with a 12-second period. That’s quality groundswell, energy at 955. It’s going to be clean, powerful, and well-shaped on the reef. This is a standout for the advanced surfers. The afternoon holds with a similar 6ft east swell, energy up to 1005, and a cross-off breeze. Two great sessions in one day.
The following days, July 24-26, see swells around 5ft to 6ft, periods still at 12 seconds, with offshore or cross-off winds. The morning of July 25 (Saturday) is clean with a west-northwest cross-off at 9 mph and 5ft swell. Not a standout, but a solid option.
By July 28-29, the swell drops to 4ft and smaller, with offshore winds but weak energy – below 214. Just a longboard day.
Best bets: Wednesday, July 15, for the big wave crew, and Thursday, July 23, for the cleanest, most consistent power. That’s where you want to be.
Rusty.
