The Lowdown

G’day, Rusty here. Look, I’ll level with you – for the next week and a half, it’s gonna be a tough watch. We’ve got a small window of decent stuff right at the start, then a long, flat gap until the very end of the forecast. Let’s break it down.

Little Austi and Main Beach

The first real action kicks off on Saturday, 1st of August. The morning’s a bit ordinary with a light cross-onshore breeze and small wind ripples, but the swell is there at 5 ft from the SSE. The water’s sitting at 65°, which is pretty much normal for the time of year. The real highlight is Saturday afternoon – the wind goes glassy, dead calm. The swell drops a touch to 5 ft, still from the SSE, and the combined energy is moderate (368). Expect good surf conditions. It’ll be clean, fun, and definitely the pick of the first few days. Crowds are sometimes a thing here, so keep an eye out.

Sunday, 2nd of August, is a standout. The morning is firing: a clean 6 ft from the SSE, with a long 13-second period, and a cross-offshore NNW wind at 9 mph. The combined energy is strong (910). This is proper groundswell, and it’s going to be a very good session. The afternoon goes a bit ordinary with a cross-shore chop, so get in early.

Monday, 3rd of August, drops off fast. The swell halves to 3 ft in the morning, and while it’s clean and offshore, the energy is weak (187). It’s surfable, but nothing to write home about. After that, from Tuesday, 4th of August, right through to Friday, 14th of August, we hit a massive flat spell. Swell heights drop to 0.7 ft or 1.0 ft, wave energy is weak (12 to 62), and the wave comment is consistently “poor surf conditions.” The wind is clean for most of it, but there’s just no swell to work with. This is a dry, frustrating stretch of over a week.

Now, look ahead to the very end of the forecast. On Saturday, 15th of August, the morning sees a tiny 2 ft from the E with a light offshore NNW wind – it’s clean, but still weak energy (59). Only for the desperate.

The real wildcard, and the one that gets me excited, is Sunday, 16th of August. The morning shows a solid 7 ft from the SSE, with a 13-second period, and the combined energy is massive (2008). That’s strong, powerful swell. The wind is light cross-onshore, so it won’t be perfect, but the size is there. That’s a day for experienced surfers – 7 ft is getting up there, definitely not for beginners. The afternoon drops right off to 2 ft, so the morning’s the shot.

So, the best on offer? Without a doubt, Sunday morning, 2nd of August, with that clean 6 ft and cross-offshore wind. That’s your session. And the second standout is the big swell on Sunday, 16th of August, but that’s a long way off and we’ll have to see how it shapes up. The rest is a long, flat grind.

Rusty.
