The Lowdown

Alright, let’s have a look at what’s on offer.

Okay, so the next sixteen days are a bit of a mixed bag. We’ve got a real slow start, and then a promising finish, but you’ve got to be patient. The first real surfable waves don't show up until the morning of Sunday the 9th, and even then, it’s just a little runner. The early part of the outlook is dominated by small, weak swells and a lot of "poor surf conditions" – it’s pretty flat from the 8th through to the 9th, with a real gap of nothing to get excited about.

The first chance to get wet is Sunday morning, the 9th, at Little Austi and Main Beach. It’s not a bomb, but it’s a start. We’re looking at a 3ft swell from the ENE with a 10-second period, which makes for a clean, surfable wave. The wind is from the North at 9 mph, giving us a cross-off breeze, so the faces should be tidy. The combined energy is moderate (138), so there’s some push. The water temperature is 64° with a normal anomaly for this time of year, so it’s not a shock to the system.

The standout window, and I mean the real standout, is the morning of Sunday the 23rd of August. That’s the one to circle on the calendar. Little Austi and Main Beach will see a 5ft swell from the ENE, with a 11-second period. That’s a solid, long-period groundswell, and it’s got a lot of energy behind it (513). The wind is predicted to be a light, glassy North breeze at 3 mph. That’s a recipe for clean, lined-up sets. The combination of good size, decent period, and glassy conditions makes this the best option by a long stretch. The swell is right at 5ft, so it’s a solid intermediate wave and pushy for a beginner, but it’s a great size for a keen surfer. The swell direction is ENE, which is the optimum direction for this spot, so expect it to wrap in nicely. The only downside is that this spot can get crowded sometimes, so get there early.

The morning of Friday the 21st is also worth a mention. It’s a 3ft swell from the ENE with a 10-second period, and the wind is glassy from the SSE at 3 mph. The energy is moderate (215), and it’s got good conditions. It’s a nice little warm-up for the Sunday.

The rest of the second week is a bit of a write-off. There’s a few small bumps like the 4ft on the 20th, but the wind is onshore or cross, so it’s hard to get excited. The swell on the 22nd gets up to 5ft from the ENE with a 10-second period, but the wind is onshore, so it’s likely going to be a choppy mess.

So, to sum it up: the first week is a slow grind with a tiny window of clean surf on the 9th, and the second week is all about the morning of Sunday the 23rd. That’s the one. Get your board ready for that.
