Mullaghmore Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be straight with you: this is a tough outlook for Mullaghmore. Honestly, the next week and a half looks grim. The model is showing a lot of energy, but the wind is almost always wrong for this reef, coming from the south or west-southwest, putting it sideshore or onshore and making a mess of things. We’re looking at a long stretch of poor surf conditions from now until the middle of the month. The combined swell energy will be moderate at best, often in the 200-400 range, with a few pulses pushing into the 700s, but it’s all wasted with that wind.

The first real flicker of hope comes on Thursday, the 17th of September. The swell size is forecast at 5 ft from the west, with a period of 11 seconds, delivering moderate energy (663). The big news is the wind: a light breeze from the SSE, which is straight offshore for this spot. That’s going to make the lineup glassy and clean. The water temperature is about average for this time of year, so a 3/2 wetsuit will be fine. This is the standout session of the entire forecast, but it’s a one-trick pony. The afternoon on the same day turns back onshore from the northwest, so you’ll want to be out there first thing.

After that, it’s back to the wait. The morning of Sunday, the 20th of September, has a pulse of swell hitting 8 ft from the west-northwest with a long 14-second period—that’s proper groundswell energy (2362). The wind is cross-off from the south-southwest, leaving it clean. But the forecast says "marginal," probably due to tide. That size is big, only for experienced surfers, and the long period means it might run a bit straight at the reef, but it could still produce some heavy barrels. Don’t get too excited; the afternoon turns side-on and lumpy.

Then there’s a huge pulse forecast for Wednesday, the 23rd of September. The afternoon shows a 8 ft swell from the west, with a very long period of 16 seconds. That’s massive wave energy (3563). But the wind is cross-onshore from the west-northwest, making it choppy. The forecast is again "marginal." For a reef like Mullaghmore, that’s frustrating. It’s a lot of ocean energy, but it won’t be clean. The following Thursday and Friday the 24th and 25th, the swell is up to 10 ft, but the wind is a strong onshore breeze, making it a total write-off.

So, the only real green light is the morning of the 17th of September. If you can get on it, do it. Otherwise, we’re waiting for a better wind direction.

Rusty.
