The Lowdown
G’day, Rusty here. Let’s be straight with you: the next 16 days at Lahinch Strand are a tough beat. We’ve got a run of poor surf conditions that stretches all the way from this Saturday morning through until at least the end of the period, with only a couple of barely rideable windows that are more about being in the water than scoring anything good.
The overall pattern is a drawn-out sequence of cross-on and onshore winds, mostly from the west and southwest, which just kills the shape on this open, exposed point. We’ve got a moderate amount of swell energy in the water for a few days mid-week, with combined energies hitting up to 720 (strong energy) on Wednesday the 19th, but it’s all blown to bits by fresh breezes. That big Wednesday morning surge – 6ft and 7ft afternoon from the west, with 720 of energy – is only for the brave. That’s expert-only territory at 7ft, and with 22 mph cross-on winds, it’s a washing machine, not a surf session.
The only two sessions that even tick “surfable” are the Saturday morning of the 15th and Saturday afternoon of the 22nd. That first Saturday, August 15th, has a tiny 3ft west swell with a light 6 mph cross-off breeze from the NNW, giving you clean lines. The water’s 64°, which is a touch warmer than normal for this time of year. Combined energy is 104 (moderate). It’s tiny, beginner-plus friendly, but the break is fairly consistent and the offshore wind is a rare gift. Be aware: crowds are often around here, so you won’t be alone. It’s the one standout, but it’s a small one.
Then you’ve got a long gap – a solid week of rubbish – until Saturday afternoon, August 22nd, when another 2ft northwesterly shows up with a light 9 mph cross-off breeze, making for clean little waves. The energy is weak (63). It’s surfable, but very ordinary.
After that, it’s back to flatness and onshore junk for the rest of the run. A few mornings in the third week show light offshore breezes (the 23rd and 25th), but the swell is barely 1ft – more of a paddle than a ride. There’s nothing worth chasing out of that.
If you’re desperate, get on that first Saturday morning, August 15th, for the cleanest little waves of the whole window. Everything else is a write-off.
Rusty.
