The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for this stretch.
Well, I gotta be straight with you – this is a tough run. We’ve got a huge gap of flat, junk conditions right off the bat. From Thursday the 20th of August all the way through the following Saturday the 29th, it’s mostly cross-shore wind, tiny swell, and poor surf quality. You’re looking at about a week and a half of virtually nothing worth paddling out for. A couple of mornings on the 23rd and 24th show some clean offshore wind, but the swell is down around 1.0 ft to 3 ft with weak energy (18 to 202), so it’s barely surfable.
Now, here’s where it gets interesting. The standout window is Saturday the 29th of August. We’ve got a solid 7 ft swell from the West rolling in, with light offshore winds from the ESE in the morning. The energy jumps right up to 529, and conditions are looking clean. That’s the best bet in this whole forecast. If you’re an advanced surfer and can handle a heavy reef break like Aileen's, this is the day. The water is sitting at 63°, which is a touch warmer than normal for this time of year, so no real shock there.
After that, Sunday the 30th sees a bigger 8 ft swell from the WNW, but the wind swings cross-shore and it gets messy. That size is expert-only, and with the onshore wind later in the day, it’s gonna be a battle. The energy is high at 931, but the quality drops off fast.
The rest of the run into early September stays poor – onshore winds and lumpy conditions, with only marginal windows on the 4th of September where you might find a clean 5 ft wave, but nothing that’ll blow you away.
Bottom line: if you’re keen, point your board at Aileen's on the 29th of August for the cleanest, biggest swell of the period. Anything else in this window is a write-off.
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.
