The Lowdown
Alright folks, Rusty here. Let's have a look at what the charts are telling us for Lahinch over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough run. We’re looking at a long, frustrating stretch with barely a window of decent surf until the back half of the period. The opening days are a write-off, so don’t even bother waxing up just yet.
We kick things off on Monday the 17th and it’s pretty grim. Onshore winds are ripping, creating choppy, messy conditions with a weak, short-period swell. The water is sitting at 64°F, which is a touch warmer than normal for this time of year, but that’s the only good news.
This rubbish pattern sticks around through the rest of the week. We see some bigger swell roll in on Wednesday the 19th, with waves hitting 8 ft out of the west and a period of 10 seconds. The combined energy spikes hard (1495), but that's all wasted. With howling cross-onshore winds, it's just a big, lumpy, rain-soaked mess. That size is only for the experts anyway, and even they wouldn't want it in these winds.
Finally, by Thursday the 20th, the wind does us a solid. It swings north, going cross-offshore, and cleans things up nicely. But the swell has dropped right back to 5 ft and is still a bit weak (338). The forecast calls it marginal, and I’d say that’s fair. It’s a “maybe” session for the patient ones, but nothing to get excited about. It’s the only period of clean surf in the near term.
Then it flat-lines. From Friday the 21st right through to Monday the 24th, we’re looking at tiny, knee-high dribble or just flat. A classic summer lull for the area.
Now, if you’ve got a bit of patience, things look a touch more promising in the long run. On Tuesday the 25th of August, a new, stronger swell tries to push in. We’re looking at 8 ft from the west-southwest with a decent 10-second period, and the energy is solid (963). But here’s the kicker – the winds are back onshore from the south. It’s not going to be clean. It’s a promising swell, but the wind is letting us down.
The real standout, the one I’d circle on the calendar, is actually Thursday the 27th of August. It’s a small day, with waves only around 2 ft, but the conditions are spot on. We get a proper offshore wind out of the northeast, the air is clean, and it’s glassy. Lahinch is a point break and a W’ly swell magnet, so even with a tiny groundswell, the long period (9 seconds) might wrap in a clean little wave for the longboard or a foiler. It won’t be big, but it will be beautiful.
So, to sum it up: the next week is mostly a bust. Don't waste your petrol. Keep an eye on that Thursday the 27th for a glassy, if small, session, and maybe the following Tuesday the 25th if you’re desperate for size and don't mind the lump.
Stay tuned, and check back in a few days – things can always change for the better.

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.
