The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, it’s a tough run for Aileen's (reef). The whole 16-day window is pretty much a write-off for decent surf. There’s a big gap right from the start – nothing worth paddling out for until Monday the 24th of August, and even then it’s only just surfable. We’ve got a long stretch of poor conditions before that.
The water temp is sitting at 63°, which is a touch warmer than normal for this time of year, so at least the shorty or spring suit will be fine.
The only day that even gets a nod is Monday the 24th of August. Monday morning we’ll see a small 3 ft swell from the WNW, with a period of 11 seconds. That’s a long-period groundswell, which means it’ll have some fun shape, but being a reef break, it should handle it well. The wind is offshore from the ESE at 9 mph, so the surface will be clean. The combined energy is moderate at 164. Monday afternoon stays clean with a similar 3 ft swell from the WNW, but the wind swings cross-offshore.
After that, it’s back to poor conditions. There’s a huge spike in swell on Friday the 28th of August – 10 ft from the WNW on Friday morning, and the combined energy is enormous at 1294. But the wind is a fresh cross-onshore at 22 mph, making it lumpy and messy. This is strictly for the experts only, and honestly, with that wind, it’s going to be a battle. The period is short at 9 seconds, so it’ll be a bit of a wall of white water. Not the kind of day you want to be out there unless you’re very experienced.
The rest of the month and into September is a mix of tiny, weak swells and onshore winds, with the occasional clean moment but nothing with any size or power. The swell direction is often from the NW or W, which is not the optimum WSW for this spot.
Honestly, if you’re keen, Monday the 24th of August is your best bet. The rest of the window is a right-off.

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.
