The Lowdown
Alright, this is Rusty, and we’ve got a long look ahead for Lahinch Strand here in County Clare. I’ll be straight with you—it’s a rough stretch. The water is sitting at 61°, which is a touch warmer than normal for this time of year, so at least you won’t freeze on the paddle out, but the surf quality is the real story, and it’s not a pretty one.
We’re starting off this Saturday, the 12th of September, and the energy in the water is massive, with a combined swell energy of 1412, but don’t get excited. That’s a 8.2ft west swell with a solid 10-second period, but it’s being torn apart by a 19 mph onshore wind. It’s just messy, lumpy, and blown out. That trend sticks with us for days. Sunday the 13th drops to a small 3.9ft swell, but the wind is still on it. Monday and Tuesday are much the same: onshore winds and poor conditions. The energy climbs again on Thursday the 17th with an 8.2ft swell and energy up to 1612, but again, strong cross-onshore winds ruin it.
Honestly, this whole first week is a write-off for a good paddle. The winds just don’t let up, and the swell is either too raw or too chopped. If you’re a kiter, the strong winds and big lumps on the 19th and 20th (Saturday and Sunday) might look more interesting than a surf session.
There is one standout, but it’s a bit of a tease. Wednesday the 23rd of September, morning. We get a 6.9ft west swell with a 9-second period, and the wind finally swings around to a light SE at 9 mph, giving us a gentle cross-shore. The combined energy is 653. The comment says it’s too big for this break, but with that clean wind and a west swell, it’s the cleanest looking window in the whole 16 days. It’s a long way off, so keep a loose eye on it—forecasts shift.
After that, we trail off into onshore winds and more big, messy swell right through to the 27th, where we even see a 13.1ft swell with a 15-second period and energy over 6789, but it’s pinned by a 28 mph cross-shore. Unsurfable.
So, no real glory days here. The best bet is that Wednesday morning the 23rd, and it’s a long shot from now. Keep the board waxed and the expectations low.
