The Lowdown

Alright, folks, Rusty here. Let me tell you what’s on the table for the next couple of weeks.

Honestly, it’s a pretty grim stretch for the most part. We’re looking at a long, quiet spell with very little to get excited about. The first real action doesn’t show up for over a week, so don’t bother rushing to the water.

The best chance we get falls on Wednesday, September 2nd. Mullaghmore will finally see a pulse of 6 ft swell from the West, with a period of 9 seconds. That’s a moderate energy swell (combined energy of all swells directed here is 548). The real kicker is the wind – it’s glassy, dead calm. That’s a major positive for a reef break like this, meaning the surface will be clean. The troughs will be deep, and the lines will be clean. The swell direction is straight out of the West, which is a fair bit off the optimum Northwest direction, but with that glassy surface, it’s still the best on offer.

Following that, Thursday, September 3rd morning holds some promise. The swell is 6 ft from the West, period 9 seconds, and the wind is blowing offshore from the Southeast at 12 mph. The water’s going to be clean and the wave energy is moderate (492). This is a solid, rideable day for the advanced crew. However, that afternoon the wind picks up and the looks get messier.

The rest of the run is a write-off until then. There’s a long gap from now until that Wednesday. The 6 ft swell on Saturday, August 29th is blown out by onshore winds, and the little 2 ft dribble on other days is just not worth the paddle. The biggest swell we see is 7 ft on the afternoon of Thursday, September 3rd, but it’s with a stiff cross-offshore breeze that makes it a tough, choppy affair.

The water temperature here is about average for the time of year, nothing unusual.

So, there you have it. One glassy day to aim for if you’re keen. The rest? Keep your board in the bag.

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.

Mullaghmore is 20 km (12 miles) from Killybegs. If you plan a holiday in Sligo, look for hotels and other accommodation in Killybegs. Killybegs has rooms for a wide range of budgets as well as car hire and transport links.
