The Lowdown

Alright, Rusty here. Let's have a look at what's coming down the line for Little Austi and Main Beach.

Honestly, for the next few days, you can leave your board in the shed. We're looking at some tiny, weak energy with a combined swell energy reading of just 15, and it's all coming from the southeast with a long period of 15 seconds. That groundswell is just too long and too small to do anything worthwhile on this exposed beach and reef setup. The wind is mostly off or cross-off, but there's just no swell to work with.

The real story starts to build from Saturday the 1st of August. That morning, we've got a glassy start with zero wind and a solid pulse of 5 ft swell from the SSE. That's a moderate wave energy of 537, and the period is a nice 10 seconds, which should give us some proper shape. The water temperature is sitting at 66°, which is a touch warmer than normal for this time of year. This Saturday morning window is the standout of the whole forecast – clean, punchy, and it's the best you're going to get. The crowd factor is "sometimes" here, so expect a few heads out but nothing too wild.

The good energy carries into Sunday the 2nd of August. The swell drops a touch to 4 ft from the SSE, but it's still got a clean 10 to 11-second period and a light offshore wind from the NNW. The combined energy is still a solid 378 to 302, so it's well worth a paddle. The morning will be the pick again.

After that, the swell fades into the middle of the week. We get a few smaller, surfable days on Monday the 3rd and Tuesday the 4th, but it's pretty ordinary. The energy drops right off.

Then things get a bit rowdy. By Thursday the 6th of August into Friday the 7th, the swell pumps up to 7 ft and then 8 ft from the SSE, but the wind is all over the shop – cross-shore and cross-onshore, blowing at 16 mph. The wave energy is huge – 839 and 1759 – but it's going to be a messy, choppy mess. The 8 ft on Friday afternoon is only for the experts, and even then, the conditions are marginal. The setup looks more interesting for kite surfing than paddle surfing those days.

The following weekend, the 8th and 9th of August, still has size, with 6 ft to 6 ft from the SSE, but the wind is still a problem from the NE. Sunday the 9th of August morning cleans up with a cross-off breeze and 3 ft swell, giving us one last clean session before the whole thing drops off into tiny, weak stuff again for the second week. That late run is promising but less certain this far out.

So to wrap it up: the first few days are a write-off. Your best bet is the Saturday 1st of August morning, with the Sunday 2nd of August morning a close second. Don't bother with the big, windy stuff in the middle.

Rusty.
