The Lowdown
Alright, Rusty here. Let me talk you through what’s on the table for Aileen’s over the next couple of weeks. First things first, Aileen’s is a reef slab that needs the right direction, and for the majority of this forecast, it’s not going to fire. The wind is a constant problem, and we have a long stretch of ugly, blown-out conditions before things look up.
We start off with nothing on the 2nd and 3rd of September – onshore winds from the SSW and WSW are trashing the 3.6 to 5.9ft swell, with combined swell energy ranging from 156 to 521 (moderate). It’s lumpy and poor. That sets the tone for a grim run.
The 4th of September sees the biggest swell of the whole period, pushing 9.8ft from the W with a 12-second period, and energy readings of 2864 (strong). But it’s blowing onshore at 25 km/h, so it’s going to be a total washing machine. Only for the most hardcore, and even then, not worth it. The 5th and 6th are marginal at best, with cross-onshore or cross-off winds, and the swell drops off.
From the 7th right through to the 15th of September, it’s a long, bleak stretch. The wind is nearly always cross-onshore or onshore, often fresh to strong. The swell does spike again on the 7th with a 9.8ft W swell, but near-gale winds (31 mph) blow it out completely. After that, the energy dies, and the swell gets small and weak. There’s a gap of about nine days where you wouldn’t paddle out.
Then, finally, a glimmer. On the morning of the 16th of September, the wind goes cross-offshore from the NE at a glassy 3 mph. The swell is 6.2ft from the WSW, period 11 seconds (groundswell, nice and long), and the energy is 858 (moderate). This is the standout window. That north-east wind will keep the reef clean. It’s a good-sized groundswell, but Aileen’s is a reef, so it should hold shape. Keep in mind, the period is long, so expect longer lulls between sets. That morning is the pick of the entire 16 days. The 17th also looks decent, with 4.9ft WSW swell and very light SSE cross-off winds, offering another good session.
Overall, the water temp anomaly is about average for the time of year. For the first session on the 16th, expect typical local temps.
So clear your calendar for Thursday the 16th. That’s the one to aim for. The rest is mostly a write-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.
