The Lowdown
Alright, let me tell you what I’m seeing. It’s a real lean stretch ahead for Little Austi and Main Beach. The whole 16-day window is a near-total struggle, with only a couple of tiny windows that might give you a surfable wave, but nothing to get excited about. The water is sitting at 65°, which is about average for this time of year.
The first real sniff of something comes on Monday afternoon, 3rd of August. It’s small, with a 3ft swell from the SE, and a period of 11 seconds. It’s a groundswell, so it’ll have some shape, but the energy is moderate (169). The wind is light, from the NW, so it’s clean. The report says “surfable waves but very ordinary conditions,” so it’s a pop-in for a quick session, but nothing to write home about.
Then things get grim. From Tuesday the 4th of August all the way through to the end of the window, the surf is mostly flat or blown out. There are a few moments with glassy conditions or offshore winds, but the swell is just too small. On the 5th of August, Wednesday afternoon, the wind goes glassy with a tiny 0.7ft swell from the ENE with a 13-second period, but it’s just not enough to push anything rideable. The 8th of August, Saturday morning, is glassy but only 1ft.
The only other time the report calls it “surfable” is on the 11th of August, Tuesday morning. That’s with a 2ft swell from the ENE, 9-second period, and light cross-offshore wind. It is very ordinary, though.
Later in the window, around the 12th of August, Wednesday afternoon, the swell bumps up to 4ft from the ENE, with a 9-second period and moderate energy (221). The wind is cross-offshore, but the report calls it “marginal surf forecast or questionable tide conditions.” This is the biggest swell of the whole run, but it’s not a standout. The 14th of August, Friday morning, shows 4ft from the ENE with stronger energy (270), but it’s still a “marginal” call.
Honestly, this is a tough one. There’s no standout session. The best of a bad bunch is likely the 12th of August, Wednesday afternoon, if you’re desperate for a paddle. It’s the biggest swell, but it’s not clean enough to be a true winner. Crowds are possible here, so you might have company, but it’s not like it’ll be packed for these conditions.
For the rest, it’s mostly a blank run. Don’t hold your breath. This is one of those stretches where the surf just doesn’t cooperate. It’s more of a kite-surfing setup with the wind and swell directions at times, but for a paddle, it’s a lean go.
