The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Little Austi and Main Beach.

First thing to say is, the water’s a touch warmer than normal for this time of year, sitting at 66°F, so that’s a nice little bonus if you’re heading out.

We’re staring down a pretty quiet start. From Saturday the 25th right through to the end of the month, it’s mostly flat or tiny. You’ll see a few 0.7ft bumps from the ENE, but with a weak 8-second period, the combined energy is in the single digits (9) – barely a ripple. Winds are light, mostly cross-off or glassy, so it’s clean, but there’s just no push. The surf is effectively non-existent until the end of July. On Friday the 31st, a 8ft SSE swell shows up in the afternoon, but the cross-onshore winds are blowing 12 mph and it’s choppy, so it’s not really one for the paddle. The combined energy jumps to 1000, but the conditions are poor.

The real standout comes in the first week of August. Sunday morning the 2nd is the pick of the bunch. We’ve got a clean 7ft SE groundswell with a solid 12-second period, and the wind is glassy offshore from the NW. That’s a recipe for nice, lined-up waves, especially for a beach and reef setup like this. The combined energy is a strong 1137, so there’s plenty of grunt. This is one for the experienced surfers, though – anything over 5ft is getting a bit much for beginners, and 7ft with that energy will be a handful. It’s going to be a ripper, but only if you know what you’re doing.

Monday the 3rd morning is still decent, with a smaller 4ft SE swell, clean offshore winds, and a combined energy of 275. It’s a good option for the intermediate crew, and the waves should be fun without the heavy crowd pressure – the crowds are only listed as “sometimes” here.

Looking further ahead, the second week has a few interesting pulses. Wednesday the 5th sees a 8ft SE swell pop up, but the wind is light cross-shore, making it a bit tricky. Friday the 7th morning is another potential standout: a 8ft ESE swell, glassy calm winds, and the combined energy is 836. The period is a short 8 seconds, so it’ll be a bit more of a wall of white water, but with zero wind, it’ll be clean. That’s a long-range call, so keep an eye on it, but it could be worth the wait.

Overall, there’s a long dry spell until the first week of August, then Sunday the 2nd and Friday the 7th are the ones to circle. The rest of the forecast is a mix of onshore winds and smaller, less clean swell. If you’re a beginner, wait for a smaller day in the first week. For the rest, get excited for that Sunday morning.

Stay keen.
