The Lowdown

G'day, I'm Rusty, and I've got the lowdown on what's coming for Little Austi and Main Beach. Alright, let's get into it.

We're looking at a pretty quiet start, but there's a real gem hiding in the second week. The water temp is sitting around 65°, which is pretty normal for this time of year, so that's nothing to stress about.

The first few days are a write-off. Friday the 31st of July is a total dud – tiny little 0.3ft waves and a cross-on breeze. Just don't bother. Saturday the 1st of August is where it starts to get interesting. The morning looks glassy as with a 5ft swell from the SSE. The energy is moderate (396), and that glassy wind is a massive plus – it'll be clean as a whistle. The afternoon stays clean with a cross-off breeze. This is a solid little window for intermediates.

Sunday the 2nd of August is the real standout for the first week. The morning delivers a 6ft swell from the SSE with a long 13-second period, giving it plenty of grunt (910). The wind is cross-off and clean. This is a very good-looking session, but it's pushing past 5ft, so it might be a bit much for beginners. The afternoon gets a bit messy with a cross-shore chop.

Monday the 3rd of August drops off quickly with a clean but small 3ft SE swell. It's surfable, but nothing to write home about. From Tuesday the 4th right through to Friday the 14th of August, we're in a long, flat spell. The swell drops to 0.7ft or 1.0ft, and while the wind is often clean, there's just no energy. It's a frustrating run of tiny, poor surf conditions. There's a slight bump on Friday the 7th of August to 4ft, but it's onshore and choppy, so it's a miss.

Now, hold onto your board, because Saturday the 15th of August is where it gets wild. The morning is looking exceptional for expert surfers only. We're talking a massive 16ft swell from the SSE with an 11-second period, and the energy is off the charts at 5346. The wind is a light offshore from the NNW, so it'll be clean. This is a massive, powerful groundswell and it's a true standout, but it's over 8ft, so it's experts-only territory. The afternoon drops to a still-very-solid 12ft from the SE with a cross-off wind, which is still excellent for experienced surfers. This is the one to keep an eye on, but being that far out, the details could change.

Remember, long-period swells like this can be a bit tricky at beach breaks, but this is a beach and reef setup, so there might be a bank that handles it. Just be aware it could be a bit straight. Also, with that kind of size and energy, if the wind kicks up, it might be more of a kite-surfing show than a paddle session.

The best bet on offer is the Sunday the 2nd of August morning for intermediates, and the Saturday the 15th of August morning for the experienced crew. That 16ft swell with a 11-second period and clean offshore wind is a monster. It's a long way out, so don't book the time off just yet, but get excited.
