The Lowdown
Alright, Rusty here, and I'm looking this over for you. This forecast period is a real head-scratcher. We're looking at a 16-day window, but for Aileen's, a famously advanced and inconsistent reef break that needs everything to line up, it's a pretty grim picture. The water's a touch warmer than normal for this time of year, which is a little something, but that's about all the good news.
Right off the bat, things don't look great. For the first few days, there's swell on the charts, but the wind is a total mess. Sunday the 16th has a 5ft west swell with 7-second period, but it's onshore and there's light rain. That's a hard pass. The combined wave energy is moderate at best (187) and the conditions are just poor.
We see a bit of size building into the middle of next week. On the 19th, there's an 8ft swell coming from the W with a 10-second period, and the wave energy is pumping hard (1420). But it's being blown out by a fresh onshore breeze. That size is also into the expert-only territory. The same goes for the 20th with a 6ft WNW swell, still cross-shore winds and a cross-chop. The numbers might look promising, but the quality just isn't there to recommend it.
Late in the month, the wind stays destructive. On the 30th, we're looking at near-gale force cross-onshore winds with 7ft swell. That's just blown-out, messy conditions. Even when the swell directions line up with the optimum WSW, like on the 25th, the cross-onshore wind ruins the party. There's a brief moment on the 21st and 22nd with clean, small waves, but they are tiny (2ft or less). No real power there.
So, that's it. I can't point to a single standout session. There are no recommended days. Aileen's just isn't going to fire in this window. The winds are all wrong, and when the swell is big enough, it's just a chop-fest. For a spot that's as fickle as this, this kind of blank run is more normal than you'd hope. The forecast can always change for the better, but right now, it's a no-go.
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.
