The Lowdown

Alright folks, Rusty here. Let's get into it for Mullaghmore. This is a classic setup that needs a very specific key to unlock, and for the next couple of weeks, that key is just out of reach.

The overall pattern is flat and frustrating. We're looking at a long stretch of small, weak swell and poor wind directions. The first real glimmer of something bigger doesn't show up until almost the end of the forecast window.

Starting off on Saturday, the 8th of August, it's a write-off. We've got a 4ft swell from the W, but it's coming with a cross-offshore wind that's making a mess of things. The water is a touch warmer than normal at 61°F, but you won't be in it long enough to care. The combined wave energy is weak (240), and the whole day is a no-go.

Sunday the 9th is more of the same. The swell drops a touch, and the wind is either cross or cross-on, leaving the surface choppy and uninviting. The energy is moderate at best (276 and 206), but the quality is just not there.

Monday the 10th is a tease. We get glassy conditions with a light SW and NW wind, but the swell is tiny, only 3ft to 2ft, and the energy is weak (90 and 88). You could probably get a fun little log out if you're desperate, but it’s not what Mullaghmore is about.

From Tuesday the 11th through to the weekend, it’s basically a flat spell. The swell drops to nothing—0.7ft, 1ft—with periods that are either too short or too long for the size. The combined energy stays in the weak to low-moderate range (15 to 102). The wind does go offshore or cross-offshore a few times, which is a positive for cleanliness, but you need waves to surf. This is a gap of nearly a week with no real recommendations.

The next bit of hope arrives around Wednesday, the 19th of August. The swell builds, but the wind turns onshore and strong, with a fresh breeze from the W and WNW. By Wednesday afternoon, we see a 6ft swell from the W with a period of 9 seconds, and the energy jumps up to 533 (moderate to strong). The problem? The wind is cross-onshore at 19 mph, making it lumpy and ugly. It's surfable for a strong paddler, but it won't be pretty.

Thursday the 20th is the standout, but it’s a long way off. On Thursday morning, we get a 7ft swell from the WNW with a 10-second period. The combined energy is a strong 833. That’s a serious amount of water moving. However, the wind is onshore from the NW at 16 mph. At 7ft, this is for experts only, and with that onshore wind, it will be a battle. It's a proper beast, but the wind will make it a messy, challenging beast. For a spot like Mullaghmore, that’s a big wave day that will demand respect.

After that, the swell drops back down through Friday the 21st and into the weekend, with the wind staying onshore or cross-onshore, so we're back to small, poor conditions.

So, the long and short of it: the only real event on the cards is that solid pulse around Thursday the 20th of August. It has size and power, but the wind is a real spoiler. For the next two weeks, it's a case of watching and waiting. The surf here is picky, and it’s being particularly stubborn right now.

Stay patient, 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.
