The Lowdown
G’day, Rusty here. Let’s talk about Mullaghmore for the next 16 days. To be honest, the first week is a dud. Tiny surf and rubbish wind. But stick with me, because there’s a thunderous pulse of swell coming in the second week that’ll make it worth the wait.
From now up until the 20th of August, you’re looking at swells barely breaking 0.7ft to 4ft, with combined energy readings mostly under 300, often down in the double digits—weak stuff. Winds are mostly cross-onshore or side-off, leaving the surface choppy or with ripples. A couple of glassy mornings, like the 16th of August at dawn (WNW 3 mph, glassy), but with only 2ft of weak 7-second swell and a combined energy of just 48, there’s nothing to ride. Kite surfers might get a kick from the 14th to the 15th, with westerly winds and moderate energy around 111 to 167, but for a paddle surfer, it’s a flat-out no.
The real standout hits on Friday the 21st of August. The morning is the one you want. We’ve got a solid 8ft swell from the WNW with an 11-second period—proper groundswell. The combined energy rockets to 1375, which is strong. Best of all, the wind is light and offshore from the SSE at 9 mph, promising clean, lined-up bombs. At this size it’s expert-only; beginners should stay well clear. The swell direction (WNW) is a perfect match for Mullaghmore’s ideal NW, and being a sheltered reef break, it should hold up beautifully. The afternoon of that same day is a close second: still a punchy 8ft from the WNW, energy at 1121, but with a cross-off breeze from the SSW at 12 mph making it a touch less perfect. The morning is the clear winner.
After that, the 22nd of August settles back to a more manageable 5ft from the WNW in the morning (energy 362), with clean conditions from a light cross-off southerly. It’s surfable, but nothing special compared to the day before.
Water temperature at Mullaghmore is about average for this time of year, no surprises.
First week is a slow, frustrating slog. But that Friday the 21st morning looks like a proper gold mine if you’ve got the nerve. Long-range, but it’s a good one.
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.
