The Lowdown
Righto, Rusty here. Let’s have a look at what’s on the cards for Shark Island (Cronulla). It’s a reef break, so it handles a bit of size, but we’ve got a slow start. The water’s sitting at 64°, which is bang on average for this time of year, so no surprises there.
We’re in a flat spell right now with basically nothing doing until Thursday morning, July 30. That’s a couple of days of waiting. Come Thursday morning, we finally see a pulse of 5 ft southerly swell, with a period of 9 seconds, and the wind is light offshore from the southwest. That’s a clean start, but the energy is moderate (358) – nothing to write home about. Thursday afternoon pushes up a bit to 6 ft, still southerly, but the wind swings cross-offshore, so still fairly tidy.
The real standout is Friday morning, July 31. That’s where it’s at. We’ve got 7 ft of south swell, 11-second period, and a light cross-offshore breeze from the SSW. This is a solid, long-period groundswell, and the combined energy jumps to 1794 – strong stuff. That’s a proper session for advanced surfers, and the reef will line it up nicely. The crowd factor is “sometimes,” so you might have company, but it’s not a zoo. Friday afternoon drops a touch to 7 ft, still clean, but the wind builds a little – still a good backup.
After that, it tails off. Saturday morning (August 1) down to 5 ft with cross-shore wind, and the energy drops to 480. By Saturday afternoon and Sunday, it’s onshore, messy, and small. The rest of the first week and into the second week is a write-off – tiny swell, onshore winds, and poor conditions. There’s a brief flicker on Wednesday afternoon, August 5, with 4 ft and clean conditions, but the energy is weak (267) and it’s not worth getting excited about.
From August 6 onward, we get a bit of size again – 6 ft to 7 ft – but the wind is all wrong: cross-on or onshore, and often strong. The swell direction is mostly SSE, which isn’t ideal for Shark Island’s optimum SE direction. The energy hits 1394 on Friday afternoon, August 7, but with fresh cross-onshore wind, it’s a choppy mess. That setup is more interesting for kite surfing than paddle surfing, to be honest.
So, the one true standout is Friday morning, July 31. That’s your window. After that, it’s a long gap of poor surf until the end of the 16-day window. Hang in there.
