The Lowdown
Right folks, Rusty here. Gotta be straight with you – this is a tough one for Mullaghmore. Looking at the whole 16-day window, it’s a long wait with very little that’s truly worth paddling out for. The swell is mostly small and weak, and when it does show a bit of size, the wind is just plain ugly.
The first couple of weeks are pretty grim. From Sunday the 16th right through to Saturday the 29th, the surf is almost all in the "poor" bracket. The combined swell energy out there is weak, rarely breaking triple digits – you see readings like 37 and 38 to start, and even when it bumps up a little, the wind is either cross, cross-on, or howling from the west. That west wind is a killer here, making things choppy and lumpy. You get a tease on the 18th and 19th with some bigger swell – 5ft to 8ft – but it’s ruined by fresh to strong cross-onshore winds, turning it into a messy, blown-out nightmare. That’s more of a kite-surfing setup than a clean wave for us.
There is a glimmer on Sunday the 30th. The morning shows a promising 7ft swell from the west, period of 10 seconds, and the wind is completely glassy – zero wind from the north-northeast. That's the standout. Combined energy hits 808, which is solid, and the clean, glassy conditions will make that big slab look incredible. This is a big-wave reef for experts only anyway, and at over 5ft it’s too much for beginners and over 8ft it’s expert-only; 7ft is firmly in the expert zone. The thing is, it’s a long-range call, so don’t book the ferry just yet. The afternoon turns a bit muddy with a NW wind, so the morning window is the one to chase.
After that, Monday the 31st has some size at 7ft from the west with 11-second period and strong energy (1165), but the wind goes cross-on again, which spoils it.
All in all, we’re looking at a two-week stretch of basically nothing, then one very promising but far-off window on the 30th. For a spot like Mullaghmore, which is fairly consistent, this blank run is a bit of a surprise, but forecasts can change. Keep an eye on it, but don’t hold your breath.
Rusty.

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.
