Alright folks, Rusty here. Let's have a look at the local stretch, Little Austi and Main Beach.

We’ve got a bit of a wait ahead for anything decent, I’m not gonna lie. The first week or so is pretty much a write-off, so don’t get your hopes up for the next several days. The water temp is sitting at 65°, which is about average for this time of year, nothing to get excited about.

The first real glimmer of hope arrives on Saturday the 11th of July. We finally get a break from the cross-onshore junk. Saturday morning is looking clean with a light offshore wind from the NW and a small 4ft SE swell. The conditions will be smooth, but keep your expectations realistic – the wave energy is modest at 383.

The standout, and I mean the standout, is the Saturday the 18th of July. This is the one to circle on the calendar. It's over a week out, so treat it as a promising long-range call, but it looks bloody lovely. Glassy conditions, calm wind, and a clean 6ft SSE swell rolling in. The wave energy is up at 559, which will give it some push. For Little Austi and Main Beach (beach and reef), that combination of glassy water and a solid 6ft swell should produce some nice clean lines. It's a moderate size, but not too big for the average surfer. If you can, get on it.

Because the easterly angle lines up nicely with the spot’s optimum ENE direction, the swell will wrap in well. Just be aware, as a beach and reef setup, it can get a little tricky with the larger sets, but the glassy wind will make it all worthwhile.

For the rest of the period after that, Sunday the 19th has a small, clean 3ft wave with a light offshore, but it's nothing special. Then it drops right off into tiny and messy conditions through the final days. There's a big empty gap of flatness before that Saturday the 18th, so don't bother checking the cams until then.

In short, it’s a slow burn, but that Saturday the 18th is the real deal.

Information about the Little Austi and Main Beach Surf forecast

The above surf forecast table for Little Austi and Main Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Little Austi and Main Beach can be found by selecting the local surf guide option on the grey menu. Our Little Austi and Main Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Little Austi and Main Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Little Austi and Main Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
