The Lowdown
Right then, let’s have a look at what’s coming our way. I’m not gonna lie to you, this stretch is a tough one. Mullaghmore is a sheltered reef that needs a very specific window of swell and wind to light up, and over the next 16 days, the conditions are just not lining up. We’ve got a real dry spell here, so temper your expectations.
We kick off Wednesday the 12th with tiny, weak swell – around 1ft from the WSW, with a short 10-second period. The combined energy is a measly 34 (weak). It’s poor. Thursday the 13th brings a slight bump to 2ft from the W, but it’s still poor. Friday the 14th and Saturday the 15th are just as flat and messy. The whole first week is a write-off, I’m afraid.
The only flicker of real size comes around Tuesday the 18th, when we see a pulse of 5ft from the W on the morning, climbing to 8ft by the afternoon. The combined energy jumps to 334 (moderate) then 1085 (strong). That’s a decent amount of water moving. But the wind is all wrong – fresh cross-shore and lumpy by the afternoon, and the break quality is still rated poor. This is a setup that’s more interesting for kite surfing than paddle surfing. By Wednesday the 19th, the swell hits 12ft from the W with an 11-second period and combined energy at 2380 (very strong). That’s a powerful groundswell, but it’s blowing a strong onshore wind at 25 mph. The reef would be a washing machine – strictly for experts only.
There is one tiny silver lining right at the end. On Saturday the 22nd, the afternoon shows a rare glassy window. The swell is only 3ft from the W with a 9-second period, combined energy at 162 (moderate). It’s nothing special, but glassy conditions at Mullaghmore are a beautiful thing. That’s the only time in the whole 16 days you could even think about a clean, small-wave session. It’s not a standout, more of a “if you’re desperate” moment.
Honestly, there’s no one standout here. The whole period is dominated by poor surf conditions. A blank run like this is more normal for this sheltered spot when the Atlantic spins up too much wind. Keep an eye on it, but don’t hold your breath.

A general guide to surfing at Mullaghmore 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 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.
