The Lowdown
Right then, let's have a look at what's on the table for the next couple of weeks. I won't lie to you, it's a pretty grim stretch for Aileen's. This is a spot that demands a lot, and she's not giving anything up easy. The water temperature is sitting at 63°, which is a touch warmer than normal for this time of year, so that's a small comfort.
The first proper chance we get is a window on Tuesday the 25th of August. Now, I'm calling it "proper" but it's barely a whisper. The guidance tells me this place is for advanced crew only, and it's inconsistent, so it doesn't take much to get it going. On Tuesday morning, we're looking at a 5 ft W swell, with a period of 11 seconds. The combined energy is moderate at 583. The wind is a light cross-onshore from the WNW, so it'll be a bit bumpy, but it's the best on offer. The afternoon holds similar, with a 5 ft W swell and the same 11-second period, but the wind switches to a light onshore WSW. It's marginal at best.
After that, the next glimmer is on Thursday the 27th of August. The morning shows a 4 ft W swell with an 8-second period. The wind is glassy, coming from the SSW at just 3 mph. That's a major positive – glassy conditions at Aileen's are a rare treat. The combined energy is 185, which is weak. The conditions are described as "surfable waves but very ordinary," which is the most positive we've seen all forecast. That's your best bet, but don't get your hopes up too high.
The rest of the period is a write-off. There's a big pulse of energy from the 18th through the 20th, with moderate to strong energy readings (801 to 1314), but the winds are onshore, strong, and messy. It's a lot of water moving around, but it's all blown out. A few days have a clean look, like the 21st and 22nd, with cross-offshore winds, but the swell is tiny, around 2 ft to 2 ft. Not enough to get the reef working.
To be honest, this is a blank run for the area. Aileen's is a fickle beast, and it often takes a perfect alignment of swell and wind to show its true colours. This forecast doesn't have that. The only real standout is the glassy morning on the 27th of August, but even that's only offering ordinary waves. If you're desperate for a paddle, watch that window, but don't expect much.

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.
