The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right from the start I’ll be straight with you – this is not a good run. We are looking at a long, frustrating stretch with barely a window of clean, ridable surf, especially for a spot as fickle as Mullaghmore. The first real chance of anything half decent doesn’t appear until the 5th of September, and even then it’s not a classic. The water temperature is sitting at 62°, which is a touch warmer than normal for this time of year.
The first standout on offer is the Saturday morning of the 5th of September. A clean, cross-off breeze from the SSW at 30 mph, and we’re looking at 5ft swell out of the WNW with a 10-second period. The combined wave energy is moderate (551). It’s a reef break, so with a long period like that the sets will have some push and shape, but this is a spot for advanced surfers only. A 5ft swell at Mullaghmore isn’t a beginner wave. The offshore wind direction (SSW) isn’t a perfect match for the optimum NW, but a cross-off in this setup can still line up some great walls. Crowds are a possibility here.
From there, it’s a grim slide. The swell drops right off, the wind swings around and gets messy. The following week is flat and forgettable, with tiny, weak swell from the 11th onwards, barely breaking 1ft most days. There’s a brief look at the 13th of September, Sunday morning, with a 4ft WNW swell and 10-second period under a clean, light cross-off wind (395 combined energy). It’s surfable, but nothing special.
The middle of the second week offers no hope. Even with glassy conditions on the 16th and 17th of September, the swell is too small and weak to do anything at this heavy reef. All in all, it looks like a long blank run for the area. The forecasts can change, but right now this 16-day window is a write-off for Mullaghmore.
Rusty.

A general guide to surfing at Mullaghmore can be found by selecting the local surf guide option on the grey menu.

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.
