The Lowdown
Alright, Rusty here again. Let's break down the same forecast for Mullaghmore, but in feet and miles per hour. It’s gonna be a tough watch for a while. The water is running at 63°, which is a good bit warmer than usual for July – a solid 5° above average, so you might get away with a thinner suit.
We kick off on Thursday the 16th of July, and it’s a total dud. Waves are about 0.7 ft, onshore from the NW. The energy is weak (14). This pattern holds for a solid stretch. From the 16th right through the 23rd of July, it’s a flat spell. Nothing but tiny, wind-chopped waves with onshore or cross-onshore winds. The swell energy barely gets into the double digits, peaking at 55. It’s a proper dry spell for surfers.
The first real bump comes on the morning of Friday the 24th of July. Swell pushes up to about 4 ft from the WNW, but a cross-onshore breeze at 16 mph messes it up. The energy is moderate (245), but the conditions are poor. For this beach and reef setup, with that wind, it’s looking more like a kite-surfing day than a paddle-surfing one. The swell sticks around through the weekend, hitting 4 ft on Saturday morning, but that cross-onshore wind sticks with it.
Your best bet comes on Monday the 27th of July. By the afternoon, we’re seeing a solid 5 ft of swell from the WNW, with a long period of 12 seconds – that’s real groundswell. The combined energy is strong (589). The wind is a gentle onshore from the WNW, which is a clean wind for this spot. The next morning, Tuesday the 28th, is the pick of the bunch. The swell drops to 4 ft from the WNW, but the wind goes light and cross-off from the S, giving us clean, glassy conditions. The energy is still strong (318). This is the one to aim for. It’s an advanced break, and it can get crowded sometimes, so be ready. After that, the wind gets ugly with strong breezes and rain moving in from the 29th.
Bottom line: circle the 27th afternoon and the 28th morning. That’s your shot. Everything else is a washout.
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.
