The Lowdown
Alright, let’s have a look at what’s coming up for Aileen’s.
Right now, and for the next week and a half, it’s looking pretty grim. There’s a lot of onshore wind and cross-shore chop, and the swell is mostly messy. The water temp is running a touch warmer than normal for this time of year, but that’s small comfort when the surf is so poor.
We’ve got a long dry spell to start. From Tuesday the 18th all the way through to the end of August, the conditions are just not working. The wind is mostly onshore or cross-shore, often fresh to strong, and the swell is either too small or too short period to do anything with. The combined energy figures are low, mostly under 500 (moderate at best), and often down in the double digits. It’s a real struggle.
The first real glimmer of hope doesn’t come until Thursday the 27th of August. That morning, we finally see some offshore wind from the east blowing at 12 mph, with a 3 ft swell from the west, period of 9 seconds. The combined energy is 162 (weak to moderate), but the key thing is the wind is clean. The report says "surfable waves but very ordinary conditions," so it’s not a standout, but it’s the first sign of life. The afternoon stays offshore but the wind picks up to 19 mph, making it a bit bumpy.
After that, things close down again fast. The 28th and 29th of August are back to strong onshore winds and tiny swell. Then on the 30th and 31st, we get some cross-on wind and a bit of swell, but it’s messy.
The real standout of the whole forecast is actually the most distant. On Tuesday the 1st of September, we see a 8 ft swell from the west-northwest, but the wind is a fresh cross-onshore from the north-northwest at 19 mph, keeping the surf poor. The combined energy is 640 (strong), but the wind wrecks it. It’s too big for beginners anyway, and with that wind, it’s only for the most experienced. Still, if the wind shifts, this could be the best of the run.
Overall, there’s no day I’d say is a true standout. The best bet is the morning of Thursday the 27th of August, with offshore wind and a clean 3 ft west swell, but even then it’s ordinary. The water is a touch warmer than normal, but that’s it.

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.
