The Lowdown
Right, folks, Rusty here with the look ahead. We've only got one spot on the radar, and it's a big one.
Aileen's is on the table, and let me tell you, this is a proper big-wave slab. It's an exposed reef, it's inconsistent, and it's strictly for the advanced crew. The whole 16-day window is a bit of a rollercoaster; there's swell, no doubt about it, but the wind wants to have its say too often.
First up, the pattern. We're looking at a long, frustrating wait. There's nothing even vaguely recommended until Wednesday the 23rd of September. That's a solid 11-day gap where the winds are just ripping from the wrong quarters – cross-on, howling, and just messy. You'll see size, like an 8 ft West swell on the 12th, but with a 22 mph cross-on wind, it's a complete write-off. That kind of energy (1308 combined energy) is massive, but it's just a washing machine. Even when the swell drops to a cleaner 4 ft on the 13th, the wind stays shifty.
Then we get a few days where the swell builds again. Wednesday the 23rd and Thursday the 24th of September are the one and only standouts. For Wednesday morning at Aileen's, we've got an offshore breeze from the East at just 9 mph, with a solid 6 ft swell rolling in from the West. That's a 14-second period too – proper long-period groundswell that'll have all that power and shape. The combined energy is a serious 1279, so there's a lot of water moving. This is your window. That offshore wind will make for some clean, hollow faces. The crowd situation? It says "often" packed, and for a spot like this, when it's on, you better believe every charger in the area will be there.
That afternoon the wind swings a bit cross-off, but it's still clean and a 5 ft wave will be there. And Thursday morning, the 24th, also sees some clean, cross-off wind with a 5 ft West swell, though the period drops to 10 seconds, so it won't have the same grunt as Wednesday.
After that, the wind turns sour again. There's a big pulse on the final Sunday, the 27th of September – a 13 ft West swell – but with a 22 mph cross-on wind, it's a no-go. That's a massive 2710 combined energy, but unless you're into beating yourself up, you're better off on the beach.
So, to wrap it up. It's a long wait, but Wednesday the 23rd of September morning looks like the absolute call for the experienced chargers out there. Clean, solid, and very powerful. Get in and get your share before the crowds and the wind ruin it.
Stay sharp.

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.
