The Lowdown
G’day, I’m Rusty. Let’s talk about the surf around Aileen’s (Ireland). Water temp is sitting at 63°F, which is a touch warmer than normal for this time of year – a little bonus for the shortie.
Honestly, the next week and a half is a tough slog. The prevailing westerly and cross-onshore winds are going to make a mess of things. There’s a fair bit of swell energy passing through – we see a big spike on Wednesday 19 August with combined energy of 1802, but it’s coming with a strong onshore wind and 10ft of raw, blown-out swell. That’s for experts only, and even then, it’ll be a survival session. The best surf might be a couple of windows where the wind drops and the swell direction lines up.
The standout session is on Friday 28 August morning. The wind is light from the SW at just 3 mph, giving a light cross-onshore with small wind ripples, and the swell is 7ft from the west with a 9-second period. The combined energy is 734 – strong, powerful wave energy. It’s a decent size, so it’s for intermediate to advanced surfers, and the swell direction is close to the optimum WSW for Aileen’s. That afternoon is also okay, with 6ft and light winds, but the morning has the edge. Crowds are often a factor here, so expect company.
The rest of the period is a write-off. There’s a long stretch from Sunday 16 August right through to Friday 28 August of poor surf conditions – messy, choppy, or just too small. The energy drops away to near nothing after the 28th, with tiny 1.0ft to 2ft swell and weak energy (under 100). The swell does have long periods around 10 seconds, but there’s just not enough height to work with.
A couple of mornings on the 25th and 27th show glassy or clean conditions with cross-offshore wind, but the swell is tiny – 1.0ft to 1ft – and the energy is minimal (32 and 64). For a reef like this, that’s not enough.
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.
