The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple weeks.
Right off the bat, we’ve got a real mixed bag on our hands. The first few days are a write-off, honestly. Too much wind and lumpy conditions to even think about paddling out at Lahinch Strand (County Clare). Wednesday the 19th is a total no-go with that 19 mph cross-on and 7 ft swell just getting chopped to bits. Thursday morning the 20th cleans up a bit with a cross-off wind, but it’s still marginal. Then Friday and Saturday are tiny, with swell dropping to 1 ft or less – not worth getting wet.
After that, there’s a real dry spell. Sunday the 23rd and Monday the 24th have almost no energy, with swell heights below 2 ft and combined energy readings in the teens and low hundreds – weak sauce. Tuesday the 25th is also flat with onshore winds. So basically, from the 19th up until the 26th, there’s nothing worth chasing.
Now, the first real glimmer of hope comes on Thursday morning, August 27th. The wind goes glassy – dead calm, 0 mph – and we’ve got a 5 ft swell from the west with a 9-second period. The combined energy is moderate at 367. That’s clean, that’s rideable, and it’s the standout of the first week. The water is sitting at 63°, which is a touch warmer than normal for this time of year, so you won’t need a thick suit.
But the real gem is hiding further out. Sunday morning, August 30th, is the pick of the whole forecast. The wind is glassy again, less than 3 mph from the ESE, and we’ve got a solid 7 ft swell from the west with a 10-second period. Combined energy is 634 – moderate to strong. The forecast is for very good surf conditions. That’s the one to circle on the calendar. It’s a bit of a wait, but it’s going to be worth it. The session will be clean, consistent, and the west swell is exactly what Lahinch wants. It’s a beginner-plus spot, so 7 ft is fun for intermediate surfers, but not too big for a confident learner.
After that, the wind turns onshore again from the 30th afternoon through to the 3rd of September, with the swell staying around 6 ft to 8 ft, but the wind is cross-on or onshore, so it’s going to be choppy and lumpy. The energy is strong (over 700 in some cases), but the quality just isn’t there. The 2nd of September has a 6 ft swell with onshore wind – messy. The 3rd is a write-off with a near gale from the SE. So really, the August 30th morning window is the one to aim for.
To wrap it up: the first week is a bust. The 27th gives you a clean window with moderate swell, but the 30th is the best session on offer – glassy, solid 7 ft west swell, and good energy. After that, it’s back to battling the wind. Keep an eye on that 30th, it’s a long-range call but it’s looking promising.
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.
