The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks at Aileen’s.
Right off the bat, I’ll be straight with you – this stretch is looking pretty grim for a wave. Aileen’s is a world-class reef slab, but it needs a serious push of swell from the WSW to get going, and the whole forecast period is mostly a dud. We’re looking at a long, dry run with nearly zero surfable options until the very end of the month.
The first real sign of life won’t show up until Thursday, July 24th. Even then, it’s not exactly firing. The morning shows a 3ft swell from the WNW with a period of 10 seconds, clocking in a moderate 228 energy. Wind is howling straight onshore from the W at 12 mph though, so it’s going to be a messy, blown-out affair. The afternoon is no better – 4ft, same direction, but the wind is up to 16 mph onshore. That’s not a surfable wave for a spot that needs perfection.
We scrape through the following days with tiny, weak swells and persistent cross to onshore winds. The morning of Sunday, July 27th, offers a tiny window: a 2ft swell from the W, but the wind goes glassy (NNW, 3 mph). The water temp is a touch warmer than normal at 63° with a 3° anomaly, but the swell is just too small and weak to get Aileen’s to stand up. The energy is a low 104. It’s a flat spell, really.
The most interesting swell finally arrives on Tuesday, July 29th. The morning brings a 6ft swell from the W at 10 seconds, but it’s onshore from the W at 9 mph. The energy jumps to 652 – that’s moderate wave energy. Still, the wind is killing it. By the afternoon, we get an 8ft swell from the W with a 12-second period, energy surges to a massive 2017. That’s a lot of power. The problem? The wind is still onshore from the WSW at 9 mph. For the average surfer, 8ft is big and sketchy; for a reef like this, under onshore wind, it’s a washing machine. This is advanced territory only, and honestly, with the wind, it’s more of a spectacle than a session.
The last few days of July into the 31st bring some overhead swell (5ft to 8ft) but with brutal winds – 28 mph on the 30th afternoon and 19 mph on the 31st. This is a kite-surfing setup, not a paddle surfer’s dream. The consistency is poor, and Aileen’s rarely breaks clean. The standout window, if you’re a masochist, is the afternoon of July 29th for the raw power, but the wind is trash. Honestly, if you’re not an expert looking for a beatdown, leave the board in the car.
Rusty.

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.
