The Lowdown
Right then. Let’s have a proper look at what’s on the cards for Aileen’s. This is a classic reef slab (Ireland) that needs a specific sweet spot to fire, and honestly, for the next week and a half, it’s mostly going to be a frustrating watch. The water temp is sitting at 61°F, which is a touch warmer than usual for the time of year – nothing crazy, but notable.
We kick off on Friday the 11th with a messy, cross-onshore 5ft of W swell at 8 seconds. Weak energy (278) and lumpy conditions. That’s a no-go. Saturday the 12th looks even more cooked – a jump to 8ft from the W with strong cross-onshore wind. That’s big, blown-out junk.
Sunday morning the 13th is the first little glimmer of hope. We get a clean window with a light SSE cross-offshore breeze and a small 4ft WSW swell at 9 seconds. The energy is weak (358), but it’s clean. Expect good surf conditions – small, clean, and workable on the reef, but you’ll be scratching for waves.
From Sunday afternoon right through to Tuesday the 22nd, it’s a long, bleak stretch. The wind is up, the swell is either too onshore, too big, or just messy. There’s a couple of moments with bigger 8ft+ W swells (like the 17th and 18th), but they’re all hammered by strong winds. That’s expert-only territory and even then, it’s ugly. For about a week, there’s nothing worth paddling out for.
Then, Tuesday morning the 22nd – this is the best we’ve got by a long shot. We’ve got a clean 6ft of W swell at 11 seconds under light SSE cross-offshore breezes. The energy is moderate (658), and the conditions are clean. Expect very good surf conditions. The swell direction (W) isn’t the absolute optimum (WSW), but the wind and quality make it the standout. Keep in mind that Aileen’s is inconsistent – it doesn’t always line up, so when it does, you need to be ready. The light wind will keep it glassy out there, but expect crowds to be likely – it’s a famous wave.
Wednesday the 23rd offers a marginal but clean-ish 6ft WSW swell, but the wind is cross-offshore from the SE. It’s a step down. The main event is actually Thursday the 24th. That morning shows a huge 15ft of W swell at a very long period of 15 seconds. The combined energy is absolutely massive (8088). This is a monster groundswell. For a reef like Aileen’s, that’s pure, powerful, grinding slabs. However, the wind is a light cross-shore from the S, which keeps it rideable but not perfect. This is big, expert-only territory – over 8ft, so beginners stay well clear. The long period (15 seconds) means longer lulls but heavy, deep-water pits. This is a promising but less certain call that far out (September 24th), but if it cleans up slightly, it’s the best swell of the whole window.
After that, Friday the 25th blows out entirely with a near-gale wind, and the final weekend (26th) goes marginal again with small, clean-ish but weak waves.
Overall, the highlight has to be Tuesday the 22nd for a clean, classic session. For the heavy-hitters, keep an eye on Thursday the 24th’s giant groundswell – even if the wind isn’t perfect, the power will be ridiculous.

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.
