The Lowdown
Alright, Rusty here again. Let’s talk feet and miles, same waves.
We’ve got a bit of a wait at Aileen’s. First four days are a total write-off – strong onshore breeze and sloppy, blown-out conditions. The first real chance to paddle out is Sunday, September 20th.
That morning brings a clean cross-off from the SSE at 12 mph. Swell is 6ft from the west with a long 12-second period. Combined energy is moderate at 1049. It’s a marginal call, but it’s the first rideable window.
Monday the 21st is similar but weaker. 6ft west swell, 11-second period, light SSE cross-off in the morning. Clean, but not much punch. Energy drops to 755.
Now, Tuesday the 22nd afternoon is your absolute standout. Wind dies to a dead calm from the NW – glassy. Swell is 6ft from the WSW, 10-second period. Combined energy sits at 629. The report says “expect very good surf conditions.” That glassy surface on the reef will be a dream.
Wednesday the 23rd morning is the big-wave day: 8ft west swell, 13-second period, clean cross-off from the SE at 9 mph. Combined energy surges to 2542. That’s a serious groundswell. Only for advanced surfers – over 8ft is expert territory.
The rest of the period fades. By the end of the month, swell drops to under 3ft with weak energy. Tuesday the 29th afternoon is a final bright spot: 4ft west swell, 11-second period, and a light offshore ESE breeze at 9 mph. Energy is 394, and it’s labeled “expect good surf conditions.” Worth a session.
Best pick: Tuesday the 22nd afternoon – glassy, clean, reef perfection.
Second pick: Wednesday the 23rd morning – powerful but serious size.
Crowds are “often” so expect company. Stay sharp.
Rusty out.

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.
