Alright, this is Rusty, and I'm looking at the outlook for Little Austi and Main Beach. Straight up, it's a mixed bag, and for the next little while, you're going to have to be patient. The wait for something truly worthwhile is a long one.

We kick off the 4th of July weekend, and there's just nothing doing. Tiny, weak swells with wonky wind. That early part of the outlook is pretty flat, with over a week of mostly poor conditions where the swell is either too small or badly shaped by onshore winds. The water's sitting at 66°, which is a touch warmer than normal for the time of year – something to note if you're used to a chill.

The first real glimmer of size shows up on Monday the 6th, but it's a frustrating one. We get a solid jump to 8ft of SSE swell, but the wind is cross-onshore and the whole thing looks choppy. The combined energy (1245) is moderate, but it's not going to be pretty out there.

Honestly, the only time this setup looks like it might be worth the paddle is on the 11th of July. The Saturday morning is still iffy, but the afternoon brings a real shift. The wind goes glassy from the NE, the swell drops to a more manageable 4ft from the SSE, and the energy (274) is low but clean. That afternoon window is the standout – the only period marked as "expect good surf conditions." It's not huge, but it'll be clean and fun on a beach and reef setup like this.

After that, it drops back to small, clean but ordinary conditions for a few days, and then we hit a dead calm around the 14th and 15th with zero swell. Then, from the 16th, another big pulse arrives, but again it's plagued by onshore winds. The 18th and 19th see another spike, with 12ft of SSE swell and very strong combined energy (over 5000), but the wind is cross-onshore, making it a messy, expert-only affair. The 19th morning looks glassy with that same big size, which is "excellent surf conditions for experienced surfers" – that's the only other real standout, but it's deep in the second week and less certain.

To sum it up: hold out for the afternoon of Saturday the 11th of July for a clean little session. The later stuff on the 19th is big, but you'll need to be on your game.

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.
