The Lowdown
Alright, folks, Rusty here. Looking at the next 16 days for Lahinch Strand, and it’s a quiet start with a lot of dud days. There’s little to get excited about in the first week.
Thursday, August 20, finally gives us a window. The morning has a clean surface with a cross-offshore breeze and a 6ft swell coming from the WNW. The wave energy is moderate (572). It's not a classic, but you can get a wave. It drops to about 5ft in the afternoon, still clean.
After that, it shrinks right down. You'll see some glassy days around the 23rd, but the swell is a measly 1ft, with very weak energy (28). You won't need a proper board for that.
The one real standout is on Wednesday, September 2. The morning brings a solid 7ft swell from the WSW. That’s sizeable, so let’s be clear: this is for the experienced crew only. The wind is light and cross-onshore, so it’ll be relatively clean with moderate energy (561). The big caveat here is that this swell might actually be too big for the break, making it tough to manage. But it’s easily the most powerful swell in the whole forecast period.
Beyond that, it's all small, choppy, and windy. Nothing else really challenges that September 2 session.
Rusty.

A general guide to surfing at Lahinch Strand can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
