The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles.
Honestly, the next 16 days are a complete bust for the most part. There’s a huge gap at the start with nothing to ride. It’s a lean stretch, and it doesn’t look like it’s going to change much. The only real hope is a long way out, so you’ll need to be patient.
The first decent chance isn’t until the 30th of July. That Thursday morning is the only window worth looking at. Aileen's (a notoriously inconsistent reef break) is the one to keep an eye on. We’ll see a 4ft groundswell from the WNW with a period of 10 seconds, and the combined energy will be a solid 363 (moderate wave energy). The wind is forecast to be glassy – dead calm – which is a massive plus for a spot this exposed. The water is a touch warmer than normal at 63°, so it’s about average for the time of year. This is a heavy, advanced reef, so it’s for skilled surfers only. The long period (10s) should give it some shape, which is a good thing here. Crowds are possible. It’s a rare find for this region, and it’s the only real chance in the whole outlook.
Before that, it’s a long, grim grind. The swell is tiny and the wind is almost always onshore or cross-onshore, creating choppy, poor conditions. The late part of July sees a bit of a bump in swell size, but it’s blown out with strong winds. For instance, the 25th and 26th of July have some 5ft to 5ft swell, but it’s coming with 15 to 22 mph onshore winds, making it lumpy and messy. That’s more of a kite-surfing setup than a paddle-surfing one.
After the 30th, it quickly drops back into the doldrums. The 31st of July has a clean morning, but the swell is tiny at 3ft and the energy is weak (113). Then the first week of August is a return to strong onshore winds and junk.
So, if you’re after a wave, the 30th of July is your only real shout. The rest of the time, save your energy.
Rusty.

Information about the Aileen's Surf forecast
The above surf forecast table for Aileen's provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aileen's can be found by selecting the local surf guide option on the grey menu. Our Aileen's 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 (Aileen's) 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 Aileen's 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.
