The Lowdown
Alright, let’s break this down. It’s gonna be a rough stretch for Aileens for over a week. We got swell, no doubt, but the wind is gonna be a pain in the ass – mostly onshore or cross-onshore – and that’s gonna turn it into a messy, lumpy situation. Plenty of water moving, but not the kind of wave you want to be on.
From the 13th through the 22nd, it’s mostly a write-off. There’s some size to it, up to 10 feet on the 17th afternoon, and the energy gets real strong, hitting 2316 that day, but with fresh to strong breeze and onshore wind, it’s just a churn. Not worth suiting up for unless you’re chasing punishment.
There’s a slight lull mid-period, but the wind stays annoying. Even when the swell backs off, the surface is still junk.
Now, the 23rd finally shows a change. It’s small – 2 to 3 feet – but the wind swings offshore and it’s clean. Still, it’s marginal, so don’t get your hopes up too much.
The one day to circle is the 26th of September. Saturday morning. Clear skies, a light offshore breeze, and a solid 6-foot plus WNW groundswell. The period is 15 seconds, so there’s real power and long, clean lines. Energy is a strong 1633, and everything lines up. This is the day. It’s a reef, exposed, and with that swell direction and period, it should be cooking. Aileens is always an advanced wave, and this will be no exception.
The 27th and 28th are still worthwhile – 5 feet, clean with offshore or cross-offshore winds – but that 26th morning is the standout. After that, the power fades, but it’s still a decent finish to the window.
Just a heads up, this is a long-range forecast, so stay flexible. But if it holds, the 26th is the one you want to be in the water for.

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.
