The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for our little corner of the lineup.
Honestly, folks, it’s a bit of a tough stretch. We’ve got a solid 16-day window, but the first week and a half is pretty much a write-off for any proper paddle surfing. The main spot in the crosshairs is Mullaghmore, a serious reef slab that only the advanced crew should even think about. The water’s a touch warmer than normal for this time of year, coming in at 61°F, which is notable but not gonna change the game.
From Thursday the 30th of July right through to Tuesday the 11th of August, it’s a long, flat, frustrating grind. We’re looking at tiny, weak lumps of swell – think 0.7ft to 1ft – with energy readings barely scraping into double digits (9 to 68). The wind is mostly a mess of cross-onshore or messy cross-shore, keeping things choppy and unrideable for a wave this demanding. There’s a little glimmer on the morning of Sunday the 2nd of August with clean conditions and a light easterly, but the swell is just too small at 2ft to fire up that reef. It’s basically a no-go zone for the first 12 days.
Now, things finally start to show a pulse heading into the second week. Around Tuesday the 11th of August, we get a little bump of energy, and by Thursday the 14th of August, there’s some proper size on the cards. The morning of Friday the 14th of August sees swell hitting 4ft from the WNW with a combined energy of 235 – that’s a moderate, but solid push. The wind is a light cross-onshore from the WSW, which is okay but not perfect. This is the standout window. The afternoon of that same Friday lifts even more – 5ft from the WNW, period stretching to 10 seconds, and energy jumping to 378. The wind stays light from the WNW, which is onshore, but the size and potential are there for an expert crew to really sink their fins in.
Just keep in mind, this is a deep-water, sheltered reef that needs a very specific NW swell and decent wind to be its best self. The direction we’re getting here is a bit west of its optimum, and the period is only just getting into groundswell territory. It’ll be heavy and dangerous, but for those with the skills and the nerves, the 14th of August looks like the only real chance in this entire outlook to score something heavy. The crowds can be a factor here, but with the conditions being so specific and the week-long flat spell, it’ll likely just be the die-hards.
Keep your eyes on that forecast, but don’t hold your breath for the next ten days. Get the jobs done. The ocean will come back to life.
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.
