The Lowdown

Alright, Rusty here, lookin' at the charts for the little stretch of beach we call Little Austi and Main Beach. Gotta be straight with you—the next 16 days are a bit of a mixed bag, but there are a couple of windows worth paddling out for.

First up, the water temp is sittin' right around 65°, which is pretty much normal for this time of year, so no wetsuit drama.

We're in a quiet spell to start. The first real chance to get wet comes on Saturday, August 1st. The morning is a bit iffy with a light cross-onshore breeze and a 5ft SSE swell, but it's the afternoon that's the real treat. The wind drops to nothing, glassy conditions, and that swell settles to a clean 5ft from the SSE. The energy is moderate (410), and with a 9-second period, it's a nice, manageable wave for an intermediate surfer. It's not huge, but it's clean and fun.

Now, the standout of the whole outlook is undeniably Sunday morning, August 2nd. We're talkin' a solid 6ft swell from the SSE, and the period jumps up to a proper 13 seconds. That's groundswell, boys, with real push and shape. The combined energy hits 910, which is a solid moderate-to-strong bump. The wind is a clean offshore from the NNW, makin' for some beautiful, clean lines. This is the best on offer, no question. The break is fairly consistent, so you'll get waves. Just keep an eye out—crowds are possible here, especially on a Sunday morning with surf like that.

After that, the swell fades fast. We get a few small, clean windows on Monday morning, August 3rd, with a 3ft SE swell and offshore winds, but it's weak (186 energy). The rest of that week and into the next is a real snoozer, with barely a ripple until the weekend of August 8th.

Saturday, August 8th, shows a bit of life again in the morning. A 4ft SSE swell, clean with a light NNW offshore, and the energy is moderate (200). The period is short though, only 8 seconds, so it'll be a bit softer and more crumbly, but still a fun little session for a longboard or a fish. The afternoon gets chopped up by a cross-shore.

The second week is pretty flat. There's a small bump on Tuesday, August 11th, with a 2ft ESE swell and a longer 11-second period, but the energy is low (132) and the winds are strong cross-offshore, makin' it tricky. A glassy morning on Thursday, August 13th, with a 2ft, 11-second E swell is about as good as it gets, and that's a real knee-high affair.

So, if you're a surfer, your best bet is that Sunday morning, August 2nd. Saturday afternoon, August 1st, is a close second for a glassy, user-friendly wave. The rest is mostly a waitin' game.

Rusty.
