The Lowdown
G'day, Rusty here, and I've got the lowdown for the next couple of weeks at Yo-Yo's-The Hook (reef). This is a very consistent, exposed reef break that's mostly going to be for the experienced crew. The water is sitting at a balmy 79°, which is bang on average for this time of year.
The pattern is a long, drawn-out run of solid SSW groundswell, with a few periods of big, powerful surf. The winds are nearly always cross-off or cross-shore from the SE, so the surface will be clean for the most part. The combined energy of the swells is massive, often in the very strong range, so this is a high-energy zone.
The real standout window is the Monday the 11th through to the afternoon of Tuesday the 12th. You're looking at a solid 10 ft of SSW swell, with a very long period of 17-19 seconds. This is heavy, powerful groundswell, and the combined energy is massive. With the cross-off breeze, it'll be clean. This is serious, big-wave territory for experts only. If you're a beginner, steer well clear.
The run-up to that is still good. From Tuesday the 4th through to Sunday the 9th, the swell sits between 5 ft and 8 ft, with periods of 14-17 seconds, so consistent and clean. The combined energy is moderate to strong. The surf is a bit marginal for the best tide windows, but the quality is there for experienced surfers.
There's a bit of a lull on Monday the 10th morning, with a drop to 5 ft but a very long 20-second period. The swell direction is a bit wonky, creating a cross-chop, so it's not the best.
After the big Monday-Tuesday peak, the swell drops back to 6 ft-8 ft for the rest of the week. The conditions remain clean with cross-off winds, so there's plenty of solid, rideable waves.
Then, looking way out to Wednesday the 19th, another big pulse of 10 ft SSW swell pops up, with a period of 17 seconds and the combined energy hitting a massive 6388. That's a long-range call, but it looks promising. The wind is cross-off, so it could be another epic day for the experts.
Overall, the best bet is the big swell on the 11th and 12th of August. It's big, it's powerful, and it's clean. Get on it if you've got the balls.
Rusty.
