The Lowdown
Alright, Rusty here again, but I’ll switch it up for you in feet and miles.
So, for Aileen's, we’re looking at a top-tier reef break that’s strictly for advanced surfers. The water temp is pretty normal for this time of year. The first ten days? Total garbage. We’re talking from now all the way through to Saturday, August 29th, with nothing but onshore wind, chop, and poor surf. The swell energy is mostly weak to moderate, barely cracking a hundred in some spots. It’s a long, dry spell.
Then, on the morning of Saturday, August 29th, things get interesting. The wind switches to a clean cross-offshore from the SE, and the swell pumps up to about 10ft at 9 seconds from the West. That’s a serious amount of water, with combined swell energy hitting 1271 (strong energy). It’s not the perfect optimum direction (WSW is ideal), but it’s close enough. This is the standout session, but 10ft on a reef is expert territory. Don’t even think about it if you’re not comfortable. It’s an inconsistent spot, so this lining up is a big deal, but expect crowds because they’re often here.
Monday, August 31st, morning also looks decent: about 8ft from the WSW at 9 seconds, with clean cross-offshore wind. Swell energy is 853 (moderate to strong). A good backup, but not as gnarly as Saturday.
After that, the wind goes bad again. By Tuesday, September 1st, we’ve got 10ft to 12ft of lumpy, onshore mess. That’s more of a kite-surfing show than a paddle session.
So, in a nutshell: ten days of nothing, then a solid window Saturday morning, August 29th, with Monday morning, August 31st as a solid follow-up. Both are for the brave only. Long-range stuff is promising but less certain. That Saturday is your best bet.
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.
