The Lowdown
Right then, let's talk about Aileen's. I've been looking at the charts, and honestly, it's a tough run ahead. The first week or so is pretty bleak. For the next several days, from Tuesday 18th August right through to Monday 24th, we've got a mess of strong onshore and cross-shore winds, mostly from the west. The swell is there, pushing a moderate combined wave energy (482 to 814), but it's all for nothing with these winds. It's a classic case of the ocean looking mean and blown-out, not worth paddling out. The water temp is about 63°F, which feels a touch warmer than normal for this time of year.
Things start to get interesting around Tuesday 25th August. We get a clean-looking window with a cross-offshore breeze from the SSE, and a solid 5ft swell from the WSW. The energy is moderate (336), and the period is a workable 9 seconds. This is your first genuine chance all outlook. Then Wednesday 26th has some size, 4ft from the W with an 11-second period, which is a nice groundswell pulse, but it's blowing straight onshore again, so it'll be bumpy.
The real standout, the one you want to circle on the calendar, is looking like Wednesday 2nd September morning. There's a 7ft WSW swell rolling in, with moderate energy (561) and a cross wind from the south. The catch is the period is a short 8 seconds, so it won't have the same grunt as a longer period swell, but the setup looks significantly better than anything else. This size gets into the expert zone, but for the crew that knows this reef, that's when it gets proper. It's not a perfect forecast, but it's the best gamble on offer.
Beyond that, the end of August and start of September has occasional pulses, but the wind looks to swing back onshore or cross-shore. There's a few days there in the second week with potential if the wind gods play ball, but it's too far out to bank on.
Overall, the next 16 days are mostly a write-off for Aileen's barring that window around the 25th August and the morning of the 2nd September. Gotta be patient for this one.

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.
