The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Lahinch over the next couple of weeks.
Right off the bat, I gotta be straight with you – the first ten days or so are a write-off. We’re looking at a long, frustrating stretch of poor surf conditions. The wind is just relentless, mostly cross-onshore or onshore, and it’s blowing hard. The water temp is sittin’ around 62°, which is a touch warmer than normal for this time of year, but you won’t be feeling it through the wetsuit because you’ll be too busy getting battered.
It kicks off Friday the 4th of September with a big 12ft west swell, but the wind is a fresh cross-onshore at 22 mph, making an absolute mess of it. The combined energy is massive (3172), but it’s useless for a paddle. That big swell and poor wind pattern hangs around for days. Saturday the 5th has a bit more size, but the wind is still bad. Sunday the 6th through to Tuesday the 8th? Forget it. We’ve got onshore winds of 22 to 25 mph and messy, lumpy conditions. The waves are big, over 8ft at times, but that’s expert-only territory even if the wind was kind, and it’s not. Honestly, for a stretch like that, the setup at Lahinch Strand (a point) looks more interesting for a kite surfer than a paddle surfer.
There’s a slight improvement around the 12th of September, with a smaller 5ft west swell and a gentle cross-shore wind Saturday morning, but the energy is weak (416) and the conditions are still just marginal. The wind then swings back to bad for the rest of that week.
Now, hold on to your board, because there is a true standout hidden in the second week. Thursday the 17th of September. That’s our window. Forecast is for a 4ft swell from the west-northwest, but the wind is set to be glassy – a clean 3 mph from the NE. That’s the magic word: glassy. The combined energy is weak (245) but it doesn’t matter when the ocean is like a mirror. For a break like Lahinch, this is the best we’re gonna get. The swell direction isn’t the perfect west, but it’s close enough, and the period is a solid 10 seconds. That’s a good, clean, long-period groundswell that will wrap in nicely. The crowd profile says "often" so don’t expect to be alone, but for that quality, you’ll have to share. It’s a fairly consistent break, so the waves will be there. This is the one to circle on the calendar. After that, the energy drops right off into nothing.
So, the verdict: Suffer through the first week and a half of windy, lumpy, blown-out surf. It’s a tough stretch, but it won’t stay poor forever. The only real, honest-to-goodness standout is the morning of Thursday the 17th. Set your alarm for that one.
Rusty.
