The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Mullaghmore.
Straight up, it’s a tough start. For the first several days, we’re looking at a whole lot of nothin’. From Wednesday the 22nd right through to the end of July, the swell is tiny, the wind is mostly onshore or cross-on, and the whole setup is just poor. There’s a gap of about nine days where you’d be better off waxing your board at home. The combined wave energy is weak, barely registering in the double digits or low hundreds (34 to 550), and the periods are short, meaning no real push. It’s just flat and messy.
The first real glimmer shows up on Monday the 27th of July. The swell starts to pick up a little, with waves around 5ft to 6ft from the west, with a 10-second period. The wind turns cross-offshore from the SSW, cleaning things up nicely. The combined energy jumps to a moderate 423 to 587. It’s still only a marginal day, but it’s the best we’ve seen in a while. By Tuesday morning the 28th, the wind swings cross-shore and it gets choppy again, so that window is narrow.
Now, hold onto your leash. The standout, and I mean the real standout, is Saturday the 1st of August. We’ve got a solid 11ft to 13ft west-northwest swell rolling in, with a 11-second period. The combined energy is massive – 3249 to 3663, that’s some serious power. This is a big wave day, and it’s only for the experienced crew. The wind, though, is the problem. It’s onshore in the morning and cross-on in the afternoon, so it’s gonna be a bit of a battle. This is a reef break, so that long-period groundswell will be lining up nicely, but the wind will chop it up. For the experts only, and keep your wits about you.
After that, Sunday the 2nd of August sees the swell drop back to 5ft to 6ft, but the wind is still onshore or cross-on, so it’s messy again. Then it’s back to small, weak surf for the rest of the period.
The water temperature is about what you’d expect for this time of year, nothing wild.
So, if you’re lookin’ for the one window, it’s that Monday the 27th of July for a clean, moderate session, or the big Saturday the 1st of August if you’re a proper charger. The rest of the time, it’s a waiting game.
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.
