The Lowdown
Alright, surfers, Rusty here. Let's break it down.
We're looking at a pretty quiet stretch ahead for Little Austi and Main Beach. The water's sitting at a normal 64° for this time of year, so that's about what you'd expect.
The real action, if you can call it that, is a tiny window on Monday the 3rd. We've got some small, clean waves rolling in during the morning. You're looking at a 3-foot swell out of the SE with an 11-second period, and the wind is offshore from the NW at 9 mph. It's not much, but it's the best we've got in the near term. The combined energy is weak (193). The afternoon stays clean with a lighter NW breeze at 6 mph, but the swell drops to 3 feet. It's surfable, but very ordinary.
After that, it's a desert. From Tuesday the 4th right through to the end of the first week, we're looking at scraps. Swell sizes barely crack 1 foot, and the energy is in the low double digits. You'll see some glassy conditions on the morning of Friday the 7th and Saturday the 8th, but with no swell to speak of, it's just a flat, pretty lake.
We finally get a little bump up around Wednesday the 12th and into the second week. The morning of the 12th sees glassy conditions with a 2-foot, 9-second swell from the ENE, and the afternoon picks up slightly to 3 feet with a bit more energy (108). It's still small, but it's clean. Then things get a bit more interesting on Friday the 14th of August. We've got a 7-foot swell from the NE, but the period is a short 9 seconds and the wind is a messy cross-shore from the SSW at 9 mph. The energy jumps to moderate (607), but it's going to be a lumpy, bumpy mess. This one is for the experienced crew only, and even then, it's a gamble.
The very end of the outlook, on Monday the 17th, shows another glassy morning with a tiny 2-foot swell, but it's too far out to call anything special.
Honestly, the standout here is the Monday morning session on the 3rd. It's the only time the stars align for a clean, surfable wave. After that, keep your eyes peeled for the 14th of August if you're a hard charger, but don't get your hopes up.
Rusty.
