The Lowdown
G’day, it’s Rusty here, and let’s get straight into it for the coming stretch. It’s a bit of a mixed bag, to be honest. We’ve got some proper swell showing up, but the wind’s going to be the thorn in our side for a good chunk of the next week. There are a few windows where it all lines up, and those are the ones you need to be watching.
The first real chance to even think about a paddle is this Wednesday morning, the 9th. It’s only small, around 4ft of west swell with a modest energy reading of 220. The water’s sitting at 62°F, which is a touch warmer than usual for this time of year. The issue is the cross-onshore wind, so it’s going to be bumpy and pretty average. It’s more of a “check it if you’re desperate” situation than a proper surf. That’s about as good as it gets on Wednesday, as the afternoon goes downhill from there.
We’ve got a big pulse of swell coming in for Thursday and Saturday, but the wind is absolutely howling onshore, blowing 19 to 30 km/h. We’re looking at 7ft and 7ft of west-southwest swell, with energy jumping right up into the 846 and then 1428 range. It’s going to be a messy, blown-out churn – definitely not one for the inexperienced. The size is there, but the quality is going to be rank. Thursday and Saturday are write-offs.
Friday is a bit smaller again at 5ft, but the wind is still on it, so no joy there. Sunday morning looks a little more promising – the wind swings around to a light cross-shore from the southeast. There’s still 4ft of west swell, but the energy has dropped back to 345. It’s looking marginal at best, with a questionable tide factor. Maybe a few grovelly ones if you’re keen.
Now, here’s where things get interesting. The standout of the whole period is next Tuesday, the 15th, in the afternoon. The swell jumps to a solid 8ft from the west-northwest, and the wind comes out of the north-northeast as a clean cross-offshore breeze. The energy is strong at 629. This is *the* window. The waves are going to be big, powerful, and lined up thanks to that offshore wind. It’s a proper expert-only session though – that size at Lahinch (County Clare) is not for the faint of heart. This is your one to circle. The following morning, Wednesday the 16th, has some leftovers – 5ft of west-northwest swell with a light cross-offshore breeze and clean conditions. That’s another good session, and a bit more manageable.
After that, the wind goes to shambles again for a while. We get onshores and bumpy conditions for the rest of the week. There’s a long stretch of poor quality from Thursday the 17th all the way through to the following Sunday the 20th. The wind is mainly cross-onshore or onshore and fairly strong, killing any chance of quality, even though the swell is hanging around the 4ft to 7ft range.
But just when you’re about to give up, we get another window. On Monday the 21st, the wind goes light and cross-offshore from the east, which is a dream. We’ve got 5ft to 5ft of west-northwest groundswell with a long 13-second period, and the energy is solid at 648. This looks like it’s going to be the cleanest, most lined-up surf of the second week. It’s going to be a fun one, with that long-period swell wrapping in nicely. It’s a promise of good things, but keep in mind it’s over a week away, so treat it as a promising lead, not a guarantee.
The rest of that stretch into the following week is more of the same – a lot of wind and a mix of swell, with a few marginal looks. There’s 6ft of west-northwest swell on Wednesday the 23rd with a light cross-shore wind, but the energy is down and the tide might be a factor. It’s a maybe. And the final run into the 24th and 25th is just onshore wind and lumpy conditions.
So, there you have it. It’s not an epic run of endless days, but there are two proper highlights: the bigger, more powerful session on Tuesday the 15th and the cleaner, long-period swell on Monday the 21st. If you only pick two days, make it those.
Stay stoked.

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.

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.
