The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Mullaghmore over the next couple of weeks.
Straight off the bat, I gotta be honest with you – it’s a tough watch. We’re looking at a long, dry spell with no decent surf to speak of for the first ten days or so. The opening days of the forecast, from Wednesday the 26th of August right through to the start of September, are a write-off. Tiny little dribbles of swell, most of it under 2 ft, with weak combined energy – we’re talking values like 12 or 60, barely a ripple. The wind is all over the place, cross-off or onshore, but with no wave height to work with, it doesn’t matter. You’d be better off taking the dog for a walk.
We finally see a bit of life around Monday the 31st of August, with a pulse of about 4 ft west swell showing up. The combined energy jumps to 245 (moderate), but the wind is a fresh cross-onshore, making it lumpy and messy. The score is still a zero. That’s the pattern for a few days – a bit more size, but the wind is always ruining the party.
Now, here’s the one that’s got my attention, but it’s a long way off. We’ve got to wait until Monday the 7th of September. That morning, we’re looking at a solid 10 ft swell from the WNW, with a combined energy reading of 1346 (very strong). That’s a serious amount of water moving. The wind is a clean cross-off from the SSW, which is a massive positive for this spot. It’ll be glassy offshore conditions. But hold your horses – this is a heavy-duty reef break. At 10 ft, that’s expert territory only. It’s big, it’s powerful, and it’s not for the faint of heart. The afternoon swings round to a strong cross-onshore, so the window is narrow. The rest of that week looks like a bit of a drop-off again, with smaller, wind-affected surf.
So, to sum it up: the only true standout is that Monday the 7th of September. If you’re an experienced charger and you can handle a big, clean, offshore Mullaghmore, that’s your day. Everything else is a no-go for a paddle. Honestly, for most of this period, if you’re desperate for a session on the water, the way the wind is setting up with the swell, it might be more of a kite-surfing show than a wave-riding one.
Rusty.

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 Mullaghmore 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.
