The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got on the cards for the next couple of weeks.
To be straight with you, this stretch is a bit of a heartbreaker. For a slab like Aileen’s, which is a serious reef, it needs everything to line up. For most of the forecast, the wind is howling from the wrong directions, which will put a real chop on it. We’ve got plenty of energy coming through, but for the first week or more, the conditions just aren’t going to cooperate for a clean, paddleable session.
The first real chance we get is on Sunday, the 20th of September. There’s a morning window where we get a clean breeze from the SSE, coming cross-offshore, with a 6ft (1.9m) W swell. The combined swell energy is moderate here at 984. It’s still a bit tricky, with a “marginal” tag, but it’s the first breath of hope in a long, windy spell. The crowd factor often comes into play here, so you won’t be alone if it cleans up.
The standout of the whole run looks to be Tuesday, the 22nd of September. The morning session has a clean cross-offshore breeze from the SE, with a 5ft (1.6m) W swell. The water is “a touch warmer than normal” at 61°F (16°C) for this time of year, which is about one degree warmer than average. The real kicker is that afternoon session. The wind drops to a whisper, a slight air from the NNW, making it glassy light cross-shore. The swell is up to 6ft (1.8m) and the period stretches out to a very long 15 seconds. That is proper groundswell energy, with a combined energy of 1695. For a reef like this, that long period is going to produce some beautiful, heavy lines, though it might make the takeoff a bit more critical. That is the one to circle on your calendar.
Wednesday the 23rd has a morning clean one at 5ft (1.6m) but the wind is a bit stronger, and the energy isn't as solid. After that, we get a few days of average conditions before another interesting one on Thursday the 24th of September. The afternoon brings a 10ft (3.0m) WNW groundswell, clean, cross-offshore breeze. That’s big. At over 8ft (2.5m), this is expert territory only. That’s a lot of water moving around a shallow reef.
After that, the energy fades quickly. By the 25th we’re looking at tiny 2ft (0.6m) waves, and the wind comes back onshore to finish the run. The weekend of the 27th and 28th is a write-off with fresh onshore winds in the 19-28 mph range.
So, the bottom line: sit tight through the week of wind. If you’re a solid surfer, the morning of the 20th might be worth a look. But the *true* standout, the one to build your plans around, is Tuesday the 22nd of September. Aim for that afternoon glass-off. It’s a very long period groundswell with light wind. That’s the sweet spot.
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.
