The Lowdown
Alright, folks, Rusty here. Let's have a look at what's coming down the pipe for the next couple of weeks.
To be straight with you, it's a slow start. For the majority of the next week and a half, there's just nothing doing. We're looking at a long, dry spell of flat to tiny, weak surf. The combined swell energy (6) on the 15th tells the story – barely a ripple. The wind is all over the place, mostly onshore or cross-onshore, and the swell heights barely tickle 2 ft. It's a definite gap, over a week of pretty much nothing worth paddling out for.
Now, for the patient ones, there's a flicker of hope way out in the forecast. Things start to look a bit more interesting around Saturday the 25th. We get a little bump from the WNW, with the swell energy climbing into the three-digit range (133) and the wind going glassy or light cross-off. The wave heights are still modest at 3 ft, but the conditions will be clean. That gets the heart beating a little faster.
The real standout, though, is shaping up for Wednesday the 29th. This is the one to circle on your calendar. Mullaghmore is looking at a proper pulse of groundswell from the WNW, with the swell energy absolutely hammering the 900+ mark (907). Swell heights are forecast at a solid 8 ft to 8 ft. Now, that is serious size. This is not a day for beginners – that's expert territory right there. The wind on Wednesday morning is light cross-shore with just a few ripples, which for a wave of this size at a spot like Mullaghmore is a pretty exciting prospect. Keep your fingers crossed that the long-range forecast holds, boys, because this could be the session of the month. The earlier Saturday the 25th is a solid warm-up, but the 29th is the main event.
The water temp? It started off a whopping 5° warmer than average on the 15th, feeling much warmer than normal for this time of year.
Stay patient, stay ready.

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.
