The Lowdown
Alright, Rusty here, let’s break down what Lahinch is offering.
It’s a rough start, folks. From this Sunday all the way through the following Saturday, there’s nothing worth suiting up for. The wind is hammering onshore, the swell is messy, and the waves are just lumpy and choppy. The energy is high at times – up to 3802 on Thursday the 17th – but with cross-onshore winds gusting 25 mph, it’s a mess. Not for paddling, maybe more for the kite crowd.
Then comes Sunday the 20th. This is the one. Glassy conditions – dead flat wind – with an 8ft swell from the WNW and a long 14-second period. That’s serious groundswell energy (2244 and 2386). The water’s about 61°, a touch warmer than usual. But here’s the kicker: that 8ft is too big for this break. For experts only. Beginners, sit this one out.
Monday the 21st brings back the onshore wind, and the quality drops off a cliff. By Wednesday the 23rd, we get a clean-up: cross-offshore winds from the ENE at 9 mph, with a 6ft W swell. The afternoon goes light offshore from the NNE at 6 mph, with 5ft waves. It’s clean, rideable, and the break is fairly consistent. Crowds are often, so you’ll have company, but the conditions are good for the beginner-plus crew.
After that, it’s a slow fade. From Thursday the 24th onward, the swell drops to 2ft and under, with weak energy. Clean but gutless. The period is decent, but there’s just no push.
So, bottom line: Sunday the 20th is your expert-only standout with glassy, long-period groundswell. Wednesday the 23rd is the best bet for everyone else with clean, manageable surf. The rest is a long flat spell.
Rusty.

A general guide to surfing at Lahinch Strand can be found by selecting the local surf guide option on the grey menu. Our Lahinch Strand 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.

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 Lahinch Strand 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.
