The Lowdown
Alright, folks, Rusty here. Let’s have a look at what we’ve got lined up for the next couple of weeks. I’ll be straight with you – it’s a tough run.
The entire 16-day window is pretty bleak for Mullaghmore. There’s no real standout session here. The call is for mostly poor surf conditions right through, with strong and gusty cross-shore winds dominating the picture for the first week and beyond. We’re looking at a big gap of 11 days with no decent recommendations before we see a flicker of hope.
Starting off on Sunday, the 6th, we’ve got small 2ft to 3ft swell from the west with a short, weak period of 8 seconds. The combined swell energy is a feeble 49 (weak), and while the morning has a cross-off wind, it’s a strong breeze at 25 mph, so not exactly glassy. The water temp is 62°, running a touch warmer than average for this time of year.
Monday the 7th through to Thursday the 11th sees the swell building but the wind stays messy. Monday morning jumps to 6ft from the west, but a fresh cross-shore breeze at 19 mph makes it lumpy. Combined energy climbs to moderate levels (539), but the quality is poor. Tuesday the 8th pushes up to 8ft (1480 combined energy) and even 10ft (1724 combined energy) in the afternoon, but this is accompanied by a strong cross-onshore wind at 28 mph. That’s more of a kite-surfing setup than a paddle-surfing one – the conditions are just too blown out.
The first real sign of something slightly better comes on Thursday, the 17th of September, early in the morning. We finally get a clean-looking window with a 5ft west swell at 9 seconds and a gentle cross-off breeze from the ESE at 9 mph. The combined energy is 434 (moderate) and the score is a 2 out of 10. It’s not a classic, but after this long dry spell, it’s the best we’ve got. The problem is that the same day, the afternoon turns nasty again with a fresh cross-onshore and a 7ft swell (1090 combined energy). So that morning window on the 17th is your one shot.
Beyond that, Friday the 18th and through to the 21st, it’s back to strong winds and small, weak swell. The combined energy drops well below 200 and even into double digits by Monday the 21st (87). The winds are either strong cross-shore or cross-on, keeping things lumpy and messy.
So, to sum it up: this is a long, frustrating period for Mullaghmore. There’s no big, clean swell to get excited about. The only break in the clouds is that Thursday morning, the 17th of September. If you’re itching for a paddle, that’s your best bet, but keep your expectations low. For the rest of it, you might be better off doing some maintenance on your gear.
Stay salty,
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.
