The Lowdown

Alright, Rusty here, let’s talk about what’s coming up for Little Austi and Main Beach.

We’ve got a bit of a mixed bag over the next 16 days. The first couple of days actually have some decent potential, but then it goes quiet for a long stretch before a big, powerful, but messy swell rolls in during the second week. The water temp is sitting at 65°, which is about average for this time of year, so nothing wild there.

The standout is going to be Sunday morning, August 2nd. Little Austi and Main Beach will be seeing a 6 ft swell from the SSE with a very long period of 13 seconds – that’s proper groundswell. The wind is a clean cross-off from the NNW at 9 mph, which will keep the faces nice and smooth. The wave energy is cranking at 910, so there’s plenty of grunt behind it. This is the pick of the whole period. That long period will make for some solid, lined-up waves, but it might be a bit too straight for the beach break sections, so work the ends and the reef for the best ones.

Saturday, August 1st warms things up. The morning is a bit messy with a light cross-on from the south at 3 mph and 5 ft swell, but it’s surfable. The afternoon is a real treat – the wind goes glassy, the swell drops a touch to 5 ft, and things clean right up. The wave energy is at 368, so it’s not pumping, but it’s a nice, mellow session.

Now, from Monday, August 3rd through to Friday, August 7th, the surf takes a nosedive. Swell heights drop to under 1 ft for days on end, and the energy figures are in the single digits – that’s a flat spell. It’s a long gap of about 4-5 days with no real recommendations.

Friday afternoon, August 7th, there’s a sudden jump back to 5 ft swell from the SSE, but it’s short-period (8 seconds) and onshore wind, so it’ll be a lumpy, messy affair. Not the one to get excited about.

Saturday morning, August 8th, you get a small clean-up with 4 ft swell and glassy conditions, but it’s weak.

Sunday morning, August 9th, is another decent window. A 4 ft swell from the SE with a cross-off wind from the NNW at 6 mph. The energy is 272, and it’ll be clean. A solid, fun option.

Monday morning, August 10th, has the biggest swell of the first week – 6 ft from the NE, but with a very short period of 7 seconds and a 9 mph offshore wind from the NW. The energy is 610, so there’s push, but the short period will make it a bit bouncy and fat. It’s worth a look if you’re desperate.

Then we hit the big stuff. From Thursday, August 13th onwards, things get large. Sunday, August 16th, is maxed out with 10 ft swell from the ENE, but the wind is howling from the SSW at 19-22 mph, creating a lumpy, cross-shore mess. The wave energy is massive – 1962 – but it’ll be a washing machine. For the average punter, this is a straight-up “do not go” unless you’re an expert looking for a tow-in or a beating. The entire week from the 13th to the 16th is dominated by messy, windy, big conditions. The setup here looks more interesting for kite surfing than paddle surfing during that period.

So, bottom line: Sunday morning, August 2nd, is your best bet. Get it while the getting’s good. After that, you’re waiting for a few clean windows or dealing with a beast of a swell that’s mostly blown out.

Rusty.
