The Lowdown
Alright, Rusty here again, let’s talk about Mullaghmore in feet and miles per hour. I’ll be straight with you – the next couple of weeks look like a long, flat, windy stretch with only one real chance to score.
The water’s running about 62°, a touch warmer than average for the season, which is a nice bonus when you’re suiting up.
We kick off with nothing doing. Saturday the 29th and Sunday the 30th are showing tiny, weak swell, barely hitting a foot, with combined energy in the single digits and low 30s. Not worth getting wet for. Monday the 31st picks up to about 5 ft, but it’s coming from the WNW with a 15 mph cross-onshore wind, making it a choppy, messy affair.
The first week of September is a rough ride. We see some size on the 3rd – around 6-7 ft from the west – but it’s pinned with a fresh 22 mph cross-onshore, so you’re looking at lumpy, ugly lines. Thursday the 4th is a beast on paper: a solid 11-12 ft groundswell from the west with a 13-second period, and the combined energy is absolutely roaring at 3829. But don’t get caught out – it’s blowing a strong 25 mph onshore from the WNW. For a sheltered reef break, that’s pure chaos. Only for the most hardcore experts.
Here’s the one bright spot, and it’s a long way off. Monday morning the 7th of September is showing glassy conditions with a light southerly breeze – that’s a clean offshore for Mullaghmore. You’ve got a 5 ft west swell, 9-second period, and a moderate combined energy of 417. The call is for “good surf conditions.” That’s your window. It’s the only window. Expect company if you go, because that’s a classic setup.
The rest of the second week is a write-off. We get more strong winds and onshore junk through the 8th and 9th. By the 11th, we’re looking at near-gale force winds around 30 mph and the swell is tiny again. Honestly, if you’re a kitesurfer, some of those strong cross-onshore days might be fun, but for a paddle surfer, this is a bleak outlook.
Your one and only move is to target the morning of the 7th of September. Everything else is a pass.
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.
