The Lowdown
Alright folks, Rusty here. Let’s size up Shark Island (Cronulla) for the next couple weeks. It’s a bit of a mixed bag, with a few real moments of magic, but plenty of flat and windy days in between. The water’s sitting at 62°, which is a touch below average for this time of year, so you’ll want that extra rubber.
The first proper session is Monday morning, July 20th. We’ve got a clean 6ft swell from the ENE with an 11-second period, and a light WNW cross-offshore breeze making it look real nice. The combined energy is moderate at 766. It’s an advanced reef, so it’s not for beginners, but if you’ve got the chops, this is the top pick of the whole run. The direction is a little off the best, but the wind and power make up for it.
Sunday the 19th has some size at 6ft, but the wind is cross-shore and it’s only marginal. Monday afternoon the 20th gets cooked by a NE onshore. Tuesday is small and choppy. Wednesday the 22nd is tiny, with a 3ft swell going glassy in the afternoon, but it’s just ordinary. Thursday the 23rd brings a new south swell, but the wind is strong and messy.
The next real standout is Friday morning, July 24th. A clean 6ft south swell at 10 seconds, with a light W cross-offshore breeze. The energy is solid at 702. It’s a powerful reef wave, so only for the experienced. Saturday the 25th morning has a smaller 4ft south swell with clean wind, but it’s a step down.
After that, it’s a rough ride. From Saturday afternoon through the end of July, the swell drops, the wind turns onshore, or it’s just too weak. The 30th has a 8ft south swell, but it’s howling onshore at 18 mph, making it a total mess. The start of August looks worse with heavy rain and strong winds, though the 2nd of August afternoon has a tiny 4ft east swell with a light cross-offshore, but it’s barely surfable.
So, the honest call: Monday the 20th in the morning, and Friday the 24th in the morning, are your two best bets. The rest is a whole lot of waiting.
Rusty.
