The Lowdown
Alright, let’s talk about Mullaghmore over the next couple of weeks. Honestly, it’s a frustrating outlook, and there’s no real standout day that’s screaming at you to go. We’ve got a lot of nasty cross-shore and onshore wind, which is going to mess up the quality for most of the run.
The water temperature is running a touch warmer than normal for the time of year, about 61°, so nothing too wild there.
Starting off on Monday the 7th, we’ve got a 7ft swell from the west at 10 seconds, but a strong 25 mph cross-shore wind means it’s going to be a messy, blown-out affair. Not worth your time. That theme continues into Tuesday the 8th with a bigger 8ft swell from the west-northwest, but again, strong winds – 25 mph in the morning, 22 mph in the afternoon – both onshore, so it’s just a washing machine out there.
The wind eases a bit on Wednesday the 9th, but it’s still cross-shore, and the swell drops right off to 3-4ft. The energy is weak. It’s a skip. Thursday the 10th is a bit of a tease. We get a clean, cross-offshore wind in the morning, but the swell is only 3ft from the west with a 9-second period. The energy is still low. It’s clean, but small. The afternoon gets messy again.
The next few days are a lot of the same story: small to moderate swell, but the wind is never quite right. Friday the 11th, Saturday the 12th, Sunday the 13th… all plagued by cross-onshore or strong cross-shore winds. Saturday morning does show a clean window with a 5ft swell from the west-northwest and a 13-second period, but the wind is a fresh 19 mph cross-offshore, which is okay, but the conditions are still marked as poor. The long period might make it a bit walled-off at the beach, but as a reef setup, it’s a possibility for a late session if you’re desperate.
After that, the swell drops right down. From Monday the 14th through to Saturday the 19th, we’re looking at tiny waves, mostly under 3ft, with very weak energy. The best of that poor lot is probably Thursday the 17th afternoon, where we get glassy conditions and a 2ft, 10-second wave from the west-northwest. It’s clean, but it’s barely a ripple. Friday the 18th afternoon has a gentle offshore wind and a 3ft wave, which is clean but again, tiny.
There’s a pulse of bigger swell late in the run. On Sunday the 20th, we see a 6ft swell from the west at 12 seconds, but the wind is a moderate 16 mph cross-onshore, so it’s going to be choppy and messy. The energy is strong, but the quality is poor. Then on Tuesday the 22nd, we get a 8ft swell from the west, and a 10ft swell from the west-northwest in the afternoon with a 12-second period. That’s serious power. But the wind is a near gale 31 mph and then a strong 28 mph cross-onshore. It’ll be completely blown out and dangerous. Only for the experts, and even then, it’s a grim prospect.
Honestly, looking at the whole 16 days, there’s no single session that stands out as a true winner. The wind is just too dominant. If you’re a kite surfer, those big, windy days on the 20th and 22nd might look interesting, but for a paddle surfer, it’s a frustrating run. The best chance for a clean, small wave is the glassy afternoon of the 17th, but you’ll be fighting for scraps. The bigger swell windows are all blown out.

Information about the Mullaghmore Surf forecast
The above surf forecast table for Mullaghmore provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mullaghmore can be found by selecting the local surf guide option on the grey menu. Our Mullaghmore 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.

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. 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.
