The Lowdown

Right, let’s have a look at what’s cookin’ for the next couple of weeks. I’m lookin’ at Little Austi and Main Beach – a beach and reef setup that’s fairly consistent and exposed to the ENE. It’s an intermediate kind of spot.

The water’s sittin’ at 64°, which is about average for this time of year, so nothin’ weird there.

Now, the first bit of action we’ve got is on Friday afternoon, the 21st of August. We’re lookin’ at a tiny 0.3ft wave from the NE, with a short period of 6 seconds. The combined energy is weak (58). But the wind is glassy out of the west at 3 mph, so the surface is gonna be real smooth. It’s surfable, but honestly, very ordinary.

Honestly, the rest of the run is a bit of a struggle. Saturday the 22nd through Sunday the 30th is mostly poor surf conditions. There are a few moments where the wind turns glassy, like Thursday morning the 27th and Sunday morning the 30th, with a tiny 0.3ft to 0.3ft wave, but the swell is just too weak and short-period to get excited about.

The best of a bad bunch looks like Wednesday morning, the 26th of August. The swell bumps up to 5ft from the NE, with a period of 8 seconds, and the combined energy hits a moderate 221. The wind is a light cross-shore from the SW at 9 mph, so it’s not perfect, but it’s the biggest push we see. It’s still marginal, so don’t expect a classic.

There’s a gap of a few days around the end of August and into early September where the surf is just poor. The swell is small and the wind is messy. On Tuesday morning, the 1st of September, we get a 0.3ft wave from the NE with a 10-second period, but the wind is onshore, so it’s a write-off.

Wednesday morning, the 2nd of September, offers a small 0.2ft wave from the east with a decent 11-second period, and a light cross-offshore breeze from the north. Clean, but tiny. The combined energy is only 98.

The standout – and I’m bein’ generous here – is probably that Wednesday morning the 26th of August. It’s the biggest swell we get, with moderate energy, and the wind is at least cross-shore. It’s not a day for beginners, with that 5ft wave, but it’s the only one that has a bit of push. The break is semi-exposed, so it might hold a bit of shape.

The rest of the 16-day window is a real flat spell. If you’re desperate for a paddle, the glassy mornings on the 27th and 30th could give you a few ankle-biters, but that’s about it.
