The Lowdown
G'day, I'm Rusty, and I'll be your local surf reporter for the next 16 days.
Alright, let's be blunt about it. We're looking at a pretty dire run for Mullaghmore. This is a classic, heavy reef break that needs a serious NW swell and the right wind to fire, and over the next 16 days, we just aren't getting that combo. The whole forecast period is a bit of a fizzer for paddle surfing.
The first half of the outlook is a write-off. From Saturday the 1st right through to the end of the first week, we've got tiny, weak swell and poor wind directions. The wave energy is pathetic, sometimes dropping as low as single digits, like 4 ft. It's just not happening.
There's a glimmer of something around the 7th and 8th of August, with the swell starting to nudge up over 3ft and the combined energy getting into the moderate range (228 ft on the 8th), but the wind is a cross-onshore, so it'll be choppy and messy. Not the classic Mullaghmore.
Then we hit a real gap. The 10th and 11th of August have a few moments of glassy, clean conditions with offshore winds, but the swell is tiny – under 2ft. It's a flat spell. The only real pulse of energy comes through on the 14th and 15th of August, with the swell reaching 4ft and combined energy up at 268 ft. But that's coming with strong, fresh onshore winds, making it lumpy and blown out. For a slab like Mullaghmore, that's a recipe for a washing machine, not a wave face.
Honestly, the only standout in this whole 16-day window is a very specific one. For the best chance of a clean wave, if you're a total die-hard, look at the morning of the 10th of August. Sure, the swell is only 2ft from the NW, but the wind is glassy from the north, and the water is a touch warmer than normal at 61°. The conditions will be perfect. You'll have a clean, glassy surface, but it'll be small and inconsistent, so take a longboard. Given the crowds are sometimes an issue, you might have it to yourself.
Because of the persistent strong winds and building swell, a lot of this setup actually looks more interesting for kite surfing than paddle surfing, especially when the wind really cranks up in the second week. For us surfers, it's a lean period. This kind of blank run is more normal for the area, so don't be surprised. Forecasts can change, but right now, the outlook is quiet.
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.
