The Lowdown
Alright, let's see what we're working with for the next couple of weeks here.
Right off the bat, this isn't a classic run for Lahinch. We have a long stretch of small, weak, or just messy conditions ahead. For the next several days, we are dealing with a lot of cross-off winds but the wave energy is just not there. Through Thursday the 20th and into the weekend, heights are dropping fast – we go from about 4ft down to just 1ft by Sunday, with the combined swell energy falling right off a cliff. It is going to be a flat spell, no two ways about it.
There is a little flicker of hope on Monday the 24th. The morning shows a 3ft swell from the WNW with an 11-second period, which gives it a bit of push for a groundswell. Winds are light and cross-off from the ESE, which should keep things reasonably clean. But the crowds here are often, so expect company. It is not a standout, just the best of a quiet week.
We then hit a few more days of pretty poor conditions, with building winds from the SE and eventually a fresh breeze creating lumpy, choppy seas. The swell stays small and weak until things take a dramatic turn on Friday the 28th of August. This is the one to circle on the calendar. We are looking at a 10ft swell from the WNW, with a solid period of 9 seconds and a massive jump in energy. The problem is, this is way too big for this break. For a point break like Lahinch Strand, anything over 8ft gets serious, and this is for experts only. Plus it is still a bit lumpy from the cross-shore wind. This is the real standout for size and power, but only for the most experienced surfers who know how to handle a heavy, powerful point.
After that, it drops again quickly into the start of September. There is a brief glimpse of something on the 2nd of September with a small, short-period swell from the NW, but it is weak. Nothing to get excited about.
For the first-time surfer or beginner: That Monday the 24th with the 3ft swell is about the only safe bet in the first week, but it is tiny. The big pulse on the 28th is a definite no-go if you are not experienced.
The water here is sitting at about 63°F, which is a bit warmer than usual for late August, so you might get away with a spring suit.
Overall, the first week is a write-off for decent waves. The big swell on the 28th is the one and only highlight, and it is a powerful, expert-only affair. Beyond that, it gets small and unsteady again.
