The Lowdown
G'day, I'm Rusty.
Alright, let's have a look at what's on the cards for the next couple of weeks. We're talking about Shark Island (Cronulla) here. The water's sitting at 61°F, which is a bit colder than normal for this time of year, so you'll want a decent steamer.
The first real chance of a wave doesn't come until Thursday morning, 13 August. The week leading up to that is a write-off, with onshore winds and messy conditions. Thursday morning is the standout of the entire forecast period. We've got a clean 5ft swell from the south, with a gentle offshore wind from the WSW. The combined energy is moderate at 376, and it's set to deliver clean, peaky waves. The south swell direction is a good match for the break. This is the pick of the bunch, and it's shaping up to be a solid session, but it's an advanced spot, so it'll be one for the experienced crew. Crowds are sometimes an issue here, so be prepared to share the peak.
Thursday afternoon holds a touch more size at 6ft from the south, but the wind swings cross-offshore, making it a bit more of a challenge to find the perfect line. The energy is stronger at 587, but it's not quite as clean as the morning.
Friday morning, 14 August, is still a good option, with 4ft of clean south swell and a light offshore wind, but it's a step down from Thursday. The afternoon picks up a little, but the wind goes cross-off again.
The following week, from Monday 17 August onward, things get messy. There's a run of poor surf with cross-shore winds and chop, and the swell drops off. The weekend of 22-23 August is a no-go, with onshore winds and disorganised waves. There's a spike in size on Monday 24 August afternoon, with a 6ft south swell, but the onshore wind kills it for surfing. It just looks like a messy, blown-out situation.
The last potential window is Tuesday morning, 25 August, with a clean 5ft south swell and a cross-offshore wind. The energy is moderate at 414, but it's a long way out, so keep an eye on it.
Overall, Thursday morning, 13 August, is your best bet. Don't sleep on it.
Rusty.
