The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for the next couple of weeks.
Well, I’ll be honest, the outlook for Mullaghmore is a tough one. The next wave of any real size doesn’t show up until late in the window, but the wind is a nightmare for a long stretch. We’ve got a real mixed bag of conditions, with a lot of days where the swell is there but the wind just ruins it. The first real chance of anything decent doesn’t come until Saturday the 12th of September, and even then, it’s a short window.
The whole pattern is dominated by a very strong swell event right in the middle of the first week. From Sunday the 7th through Tuesday the 9th, the combined energy is absolutely pumping – hitting four-digit values like 1070 and even 2396 on Tuesday morning – with swell heights pushing 10 feet from the WNW. That’s serious power, but the wind is howling from the WSW and WNW, cross to onshore, just making a mess of it. That’s a setup that looks way more interesting for the kite surfers than for paddle surfing. Too much wind, too much chop.
After that, the swell drops right off. Wednesday the 9th and Thursday the 10th are tiny, with swells barely over 3 feet. The water temp is sitting at 62°F which is a touch warmer than normal for this time of year, so that’s a small comfort for a paddle.
Now, the stand-out. It’s not a huge one, but it’s the only real window we’ve got. Saturday the 12th of September. The morning is looking tasty. The swell is a solid 5 feet from the WNW with a period of 11 seconds. That’s a nice groundswell with some proper energy behind it – the combined energy reads 467. But the real kicker is the wind: glassy. A flat calm, zero wind, off the NW. At Mullaghmore, a reef break that’s sheltered and needs a clean NW swell, this is the moment. It’s going to be clean, lined up, and powerful. The crowd profile says “sometimes,” so you might have a few others in the water, but for a setup like this, it’s worth it. The swell direction is dribbling in from the WNW, which is a solid match for the optimum NW direction. This is for the advanced crew though – that 5 feet on a reef with a long period can be a handful. After that, the afternoon wind swings around to a light cross-on from the W, and it’ll get a bit bumpy.
After that Saturday, it’s back to the small stuff. Sunday the 13th is tiny, and the next blip of energy shows up on Tuesday the 15th with another 5 feet swell from the WNW, but the wind is back on it, cross-onshore, so it’s choppy again. There’s a faint hope on Wednesday the 16th with a 4 feet swell and light offshore SSE wind in the morning, giving clean conditions, but it’s just average, ordinary surf.
So, bottom line: if you’re an expert with a keen eye on the wind, the only real play is that Saturday the 12th morning. The rest of the 16 days is mostly a washout with strong wind and small, messy waves. The surf is there, but the conditions just aren’t cooperating.
Rusty.

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. If you surf the same spot (Mullaghmore) 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 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.
