Alright, Rusty here. Let's see what we've got.

Alright, let's be straight with you. The next couple of weeks are a real mixed bag for Little Austi and Main Beach and we've got a massive flat spell to get through. The first proper surf worth paddling out for doesn't show up until Saturday the 11th, so we're looking at a solid 6-day gap of no-go conditions before anything decent pops up.

Starting off this Sunday the 5th, it's a write-off. We've got a tiny 0.3ft easterly windswell with a bit of rain and a strong cross-onshore wind at 18.6 mph. The water temp is sitting around 65.1°, which is pretty normal for this time of year. The swell energy is just pitiful (3). Honestly, don't even bother looking at the ocean.

Monday the 6th and Tuesday the 7th see a big jump in size, but the quality is terrible. You're looking at a solid 9.8ft of SSE swell, but it's getting hammered by a moderate cross-onshore breeze, turning it into a choppy, lumpy mess. The combined energy is up there (1496 to 2505), but for paddle surfing, it's a no-go. If you're into kites, the strong wind and messy waves might be more interesting.

The slump continues through Thursday the 9th and Friday the 10th. The swell drops a bit to 5.9ft-6.9ft, but the wind is still cross or cross-onshore, making for a bumpy, uninviting lineup. The energy is moderate (549-790).

Finally, Saturday the 11th is where we get a little glimmer. We've got a clean 4.3ft SE swell (combined energy 291) and glassy conditions in the morning with a light NW wind. It's small but clean. The best bet of the early window is Sunday the 12th of July. We score a clean 3.0ft ESE groundswell (period 11 seconds) with a gentle offshore wind from the NNW. It's small, but with the offshore breeze, Little Austi and Main Beach should have some fun, clean little lines.

Then the tap turns off again. All next week, from the 13th through the 16th, we're looking at tiny, almost non-existent swell. The best you'll see is 1.3ft with clean but weak winds. It's a proper dry spell.

Now, for the real standout – and I mean the *real* one – we have to look ahead to the following week. Saturday the 18th of July is the sneaky big one on the horizon. We're looking at a solid 9.8ft SE groundswell with a very long period (12 seconds) and light offshore NW winds. The combined energy is pumping at 2757. It's firing, but that size and period make it a big-water, expert-only zone, especially for a beach-and-reef setup like this. It'll be a bowling, powerful wave. The water might also feel a bit different come this time, given how late in the forecast this is.

Friday the 17th also gets a look-in with an 8.2ft SSE swell building to an 11.5ft SSE groundswell with a very long 15-second period by the afternoon. The wind is light and the energy is massive (4954), but the "marginal" tag suggests there might be some tide or local issues to navigate. It's another one strictly for the experienced crew. Sunday the 19th keeps the good run going with a 6.6ft SSE groundswell (period 11 seconds) and clean offshore NW winds in the morning – a very solid option for experienced surfers.

So, if you want the best on offer here, ignore this week. The real standout is Saturday the 18th of July for the experienced surfer looking for a proper, powerful groundswell with clean winds. For the smaller, cleaner, more manageable waves, the Sunday the 12th is your best bet.

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.
