The Lowdown
Alright, folks, Rusty here. Let’s have a proper look at what’s on the cards for the next couple of weeks at Aileen's.
Right off the bat, I gotta be straight with you: this forecast is a painful one for anyone keen on a paddle. We’re looking at a long, dry spell with hardly anything worth mentioning for days. The first real glimmer of hope doesn’t show up until Thursday, August 20th. That’s a full nine-day gap with nothing but poor conditions and flat dribble on offer.
The water temp is about average for this time of year, so no shocks there.
Now, for the one and only standout in this entire window: Thursday, August 20th. The morning session is the pick of the whole period. We’ve got a clean 5ft swell rolling in from the W, with a period of 9 seconds, giving us a moderate combined wave energy of 343. The wind is glassy—dead calm, slight air—which is a huge positive at this exposed reef. It’ll be clean, it’ll be rideable. But keep in mind, Aileen's is an inconsistent, expert-only reef break, so it's not for the faint-hearted, and it can get crowded often.
Later that Thursday afternoon, the swell bumps up to 6ft, but the wind swings cross-onshore and it gets a bit choppy and messy. Not the best call.
We’ve also got a pulse on Friday, August 21st that’s worth a look if you’re an advanced surfer. The morning shows a solid 8ft swell from the WNW, with a 10-second period. That’s a big, powerful groundswell with strong wave energy (1523), but it’s cross-shore with some chop. That’s big enough that beginners should stay well clear—it’s expert territory only. Still, for the crew that can handle it, that’s the biggest swell of the run.
After that, it drops off fast. The winds turn onshore and nasty from the 22nd onward, and we’re back to tiny, weak junk through to the end of the window.
Honestly, mate, if you’re not willing to wait until the 20th, it’s a tough stretch. But that Thursday morning glass-off at Aileen's looks like the real deal—just be ready for a crowd and know it’s a heavy wave.
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.
