The Lowdown
Alright, let’s have a look at the whole picture for Lahinch. We’ve got a lot of flat and messy days ahead, so don't be in a rush.
The water is a touch warmer than usual for mid-August, around 63°F, so a slightly thinner suit will do.
The first real pulse of energy hits on Tuesday the 18th and Wednesday the 19th. The swell builds to a solid 8-10ft, with energy going through the roof (1267 on Wednesday morning). But it’s a complete mess. Strong cross-onshore winds will have it all chopped up and lumpy. Not for a surfboard. Kite surfers might get a kick out of it, but for us, it’s a no-go.
We get a small reprieve on Thursday the 20th morning. The swell drops to a cleaner 4-5ft with the wind turning cross-off. It’s surfable, but it’s still pretty ordinary and the tide might be awkward.
After that, the ocean just gives up. We’ve got days of tiny, weak waves. There are a few glassy moments, like early Sunday the 23rd and Thursday the 27th, where the wind drops right off, but the swell is only ankle to knee high. Not worth the hassle.
The one window to keep an eye on is Tuesday the 25th of August, about a week and a half out. It’s a proper groundswell, 5ft but with an 11-second period, and the energy is strong (583). It’s the biggest and most powerful swell of the entire run, but the wind is a light cross-shore, leaving the surface a bit bumpy. It won’t be perfect, but it’s the best we’ve got by a long shot.
So, if you’ve got a free morning next Tuesday the 25th, Lahinch Strand is your best bet. It’s a promise, not a guarantee, but it's the one to watch.

Information about the Lahinch Strand Surf forecast
The above surf forecast table for Lahinch Strand provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
