The Lowdown
Alright, Rusty here, talkin' about Little Austi and Main Beach. It's a two-part story, and the first part ain't great.
We're staring down a real quiet spell right now. The first week is basically a full-on flat spell. The water's a touch warmer than usual for this time of year at 66°, which is a nice little bonus, but that's about it. From today, Sunday the 26th, all the way through July, the swell is tiny and weak. The combined energy is barely a blip, sitting in the single or low double digits. You'll get some glassy mornings on the 27th and 28th, but the swell is under 1 foot, so it's just a paddle. There's a solid 5-day gap with nothing to write home about.
The first real sign of life comes on Saturday, August 1st. The swell finally pushes up, with a 6-foot swell from the SSE on the morning, and a combined energy of 1004. That's some moderate energy, but the wind is cross to cross-on, so it's gonna be a bit bumpy. The tide might be a factor too.
The big one, the one you're waiting for, is Monday, August 10th. That morning we've got a solid 15-foot swell from the SE, with a 11-second period. That's a lot of water. The combined energy is a massive 4645. The wind is offshore from the NW, so it's gonna be clean. This is for the experts only – anything over 8 feet is for the big dogs. The afternoon drops a little to 12 feet from the ESE, still with a clean offshore cross-off wind from the NNE. That's a solid day for the chargers.
Before that, there's a little pulse on Sunday, August 9th. The morning is a 4-foot swell from the ESE, but it's a short 7-second period, so it won't have much shape. The wind is a clean cross-off from the north, so it'll be rideable for the patient, but nothing special.
So, bottom line: the first week is a bust, the second week has a few options, but the clear standout is Monday, August 10th. The early morning offshore session is the one to chase, but it's for experts only. The rest of the time, you're mostly looking at clean, glassy water with no push.
Rusty.
