Alright, Rusty here, let's break down what's coming for Shark Island (Cronulla).
Honestly, the next week and a bit looks pretty flat. From the 11th right through to the 20th, there’s a long stretch of very small, weak surf with poor conditions. You'll be waiting a while. The water temp is around 63°F, which is pretty standard for the season.
The real event is the big swell that arrives on the 21st of July. Tuesday morning brings a powerful 15ft southerly swell with a 12-second period. The combined energy is a massive 5682, so you know there's a ton of power behind it. That size is strictly for experts – anything over 8ft can get heavy, and this is well past that. The wind is a strong cross-off from the W, which should keep the waves fairly clean despite the size. It's not dead on the optimum SE direction, but it'll still wrap in and create some seriously heavy, grinding lines. This is the standout, for sure.
Wednesday the 22nd keeps the momentum with 7ft to 8ft of S swell, still with clean cross-off winds. The energy drops back from Tuesday’s extreme peak, but it’s still a solid, powerful day with good shape from that long-period groundswell.
So, the first week is a write-off unless you're after ankle-biters. Your window is that Tuesday/Wednesday blast – that's the real deal, but it's a big, powerful swell for experienced crew only. Keep an eye on it as we get closer, it's still a bit out there.
Rusty.
