The Lowdown
Alright, Rusty here, let’s talk about what’s cookin’ for Lahinch over the next couple of weeks.
Right now, the ocean’s a bit of a mess. We’ve got a decent-sized swell rollin’ in, around 7 ft from the west with a moderate period, and the combined energy’s sitting at 782 – that’s a fair bit of power. But here’s the rub: it’s blowin’ a solid 19 mph cross-onshore from the west, so it’s gonna be lumpy and chopped up. Not the day to be out there unless you like battling the washing machine. That wind keeps up through the afternoon, too.
Thursday the 20th looks a little better. The swell drops to 6 ft from the west-northwest, with cleaner conditions as the wind goes cross-offshore from the north at 19 mph. The energy’s still moderate at 572, but it’s surfable. The morning’s your best bet – by afternoon it’s smaller and the quality fades.
Friday the 21st through to Sunday the 23rd is pretty flat, with swell heights barely scraping 3 ft and wave energy dropping way down to around 100 or less. There’s a glassy moment on Sunday morning, but with only 1.0 ft and 20 energy, there’s really nothing to ride. You’d be better off havin’ a coffee and watchin’ the horizon.
Now, here’s where the hopeful bit comes in. Tuesday the 25th is the standout of this whole forecast. We’ve got a clean 5 ft swell from the west-southwest, a period of 10 seconds, and moderate energy at 350. What makes it special is the wind – a light offshore from the east-northeast. That’ll keep the face smooth, no chop, just clean lines rolling into the point. It’s a morale saver after a few quiet days. The water temp is 63°, which is a touch warmer than usual for August – so you can get away with a thinner suit if you’re tough enough.
After that, it kinda fades again. Wednesday the 26th has onshore wind pickin’ up hard, and by Thursday the 27th we’re back to cross-on junk. The swell stays small for the rest of the run into early September. The only other tiny glimmer is Wednesday morning the 2nd of September – the swell bumps up to 4 ft, wind’s light offshore from the north-northeast, and it’s clean, but the period’s a bit short and the energy’s only moderate.
So, bottom line: don’t hold your breath until Tuesday the 25th of August. That’s the day you want to clear the schedule. The rest of the window is mostly flat or blown out.
Rusty.

Information about the Lahinch Strand Surf forecast
The above surf forecast table for Lahinch Strand provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lahinch Strand can be found by selecting the local surf guide option on the grey menu. Our Lahinch Strand surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lahinch Strand) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
