The Lowdown

Right, let’s have a look at what’s coming up for Little Austi and Main Beach. It’s a bit of a mixed bag over the next couple of weeks, with a few windows that are worth paddling out for, but some real quiet patches too.

First up, the start of the period is a bit lean. The first spot that’s even worth a mention is Monday morning, the 24th of August. We’ve got a small 3 ft swell bumping in from the NE, with a short 6-second period. The wind is light and cross-off from the north, so it’s clean enough for a splash, but the energy is weak (66). It’s surfable, but honestly, it’s pretty ordinary.

Tuesday the 25th shows a bit more promise. The morning sees a 4 ft NE swell with a 6-second period, and the wind stays cross-off from the NNW – clean conditions. The combined energy jumps to a moderate 232, which is a step up. Afternoon bumps up to 5 ft from the NE, still clean with a north wind, and a solid 421 in energy. It’s pushing a bit for a beach and reef setup, but still manageable for an intermediate.

Wednesday and Thursday are a write-off. Wednesday the 26th has cross-on winds and rain, with poor surf all day. Thursday the 27th is small and weak, with a glassy 3 ft on the morning, but it’s just not enough.

Friday the 28th morning offers a little 2 ft SSE swell with a long 12-second period – clean with a light north wind. The energy is moderate (172), but the swell is tiny. It’s a long-period groundswell, so it’ll hold up better on the reef sections, but the size is lacking.

Now, Saturday the 29th of August is the standout in the first week. The morning is glassy, zero wind, with a 4 ft SSE swell running at 10 seconds. The energy is a solid 256, and it’ll be clean as a whistle. That’s the session to aim for – light crowds possible, but with that quality, it’s worth the gamble.

After that, it drops off. Sunday the 30th is poor, Monday the 31st is small and weak. Tuesday the 1st of September is glassy but tiny at 2 ft, and Wednesday the 2nd is similar. There’s a real gap of several days here with no real recommendations.

The second week is pretty flat overall. Thursday the 3rd of September has a 2 ft ENE swell with a moderate offshore wind from the NW – clean, but barely enough. Friday the 4th is the same story. The only thing that catches the eye is Saturday the 5th of September. We’ve got a 3 ft SSE swell in the morning with a very long 16-second period, and a 5 ft SSE swell in the afternoon with a 14-second period. The afternoon energy is strong at 839, but the wind is cross-on from the east, so it’ll be a bit lumpy. That long-period groundswell will be better on the reef sections, but it’s a promising call from the long range, so keep an eye on it.

The water temperature is about average for this time of year, no major anomalies.

So, bottom line: Saturday the 29th of August morning is your best bet – clean, glassy, and a decent chest-high swell. Don’t plan on much else until that Saturday the 5th of September window, but that’s a week and a half away and could change.
