The Lowdown
Alright folks, Rusty here with a long-range look at what’s cookin’ at Aileen’s. Strap in, because this is a proper tale of two weeks: a whole heap of frustration upfront, followed by a window that could be absolutely epic.
For the first week and a half, it’s a proper write-off. We’re looking at a solid 8-day gap with nothing worth paddling out for. The ocean is just angry – strong, howling onshore winds from the west and southwest are wrecking everything. Sure, there’s plenty of size, with swell heights bouncing between 5 ft and a daunting 12 ft, and the wave energy is through the roof—we're talking a combined energy of 3462 early on Friday the 4th. But it's all wind-chopped, messy, and blown out. You’d be fighting a losing battle. Aileen’s needs those west-southwest swells to have a prayer, and the wind is just not playing ball. Water temp’s sitting at 62°F, which is a touch warmer than normal for this time of year, but you won’t be feeling it through the spray.
We finally get a glimmer of hope on Saturday the 12th. The wind shifts to a light offshore breeze from the east-southeast and east, and the swell settles down to a clean 5 ft. The wave energy drops to a modest 432, but it’s clean and rideable. It’s the first real chance to get a couple of waves without getting hammered.
Now, let’s talk about the real standout. Mark your calendars for Friday the 18th. The morning is looking absolutely dreamy. We’ve got a solid 8 ft groundswell rolling in from the west with a long 11-second period, giving it plenty of push. The wave energy is strong at 1688. But the real kicker? Glassy conditions. Zero wind. For a heavy reef like Aileen’s, that’s as good as it gets. The water will be like a mirror. This is a serious, powerful wave for experienced surfers only—over 8 ft on a reef is no joke for the faint of heart. It’s the best on offer by a country mile, but it’s also a week and a half away, so keep your fingers crossed it holds.
After that, the window closes again into the following week with onshore winds and fading energy. So, to sum it up: suffer through the first huge gap, get a little taste of clean surf on the 12th, and aim everything you’ve got at the 18th. That’s the one.

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.
