The Lowdown
Alright, Rusty here, and I'm looking at the same picture for Aileen's. Let's be honest, the start of this run is a bust. A long stretch of nothing much happening until the final days of August. The early stuff is just ankle-biters and blown out.
The first glimpse of something surfable is on Monday the 24th of August. The swell is only about 3 feet from the WNW, and the wind is offshore in the morning. It'll be clean, but the energy is weak (196). You'll be hunting for a ride, but it's a start.
We get a bit more push on the 27th, with a 4-foot swell from the WNW, but the wind is coming across and onshore, making it bumpy. The energy is moderate (354), but the wind kills it.
The real standout is Wednesday the 2nd of September. That morning is going to be monstrous. We're looking at a solid 15-foot swell from the west, with a long 11-second period. That's a huge groundswell, and the energy reading is off the charts (4692). The wind is offshore from the ENE. This is a big, powerful, and clean wave. This Aileen's reef is going to be pumping, but at this size, it's for experts only. Everyone else, keep your feet dry. The afternoon still has 12-foot waves, clean but with a bit more cross-off wind.
Before that, the morning of the 30th of August has a window with 5-foot waves and clean conditions from a cross-off wind. It's a small window of "good conditions" but the swell is shorter period and the energy is lower (284). It's a teaser for the main event.
The morning of the 1st of September also offers a clean 4-foot wave, but it's just a warm-up for the big day on the 2nd. Water temp is about 63°F, which is a touch warmer than normal.
So, the plan is simple: wait out the flat and choppy junk for the next week. The only real day to get excited about is the 2nd of September. That's the one you want.
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.
