The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s on offer at Mullaghmore. It’s a reef setup, and it’s pretty exposed to the right swells, but looking at this 16-day window, it’s gonna be a real game of patience.
Right now, and for the next several days, we’re staring at a whole lot of nothing. The first week is a write-off, honestly. We’ve got tiny, weak swell and poor conditions. The water temp is sitting at 61°, which is a touch warmer than normal for this time of year, so the wetsuit might be a bit more comfortable than usual, but that’s the only upside.
We’re looking at a long gap of poor surf. From the start until the 9th of August, it’s just not happening. There’s a weak pulse of swell on Wednesday the 7th, but it’s cross-off or cross and the quality is shot. A big, nasty blow on Wednesday the 5th brings a massive 10ft WNW swell, but it’s accompanied by a near gale onshore wind. That’s blown out, dangerous, and definitely not for paddling. That setup would be more interesting for kite surfing than a traditional surf session.
The real standout, the only moment that’s worth getting excited about, is the morning of Sunday the 9th of August. We’ve got a solid 6ft swell from the WNW with a period of 10 seconds, and the combined energy is a healthy 600. The wind is glassy, coming from the SSW at just 3 mph. That’s the magic window. The waves will be clean, powerful, and lined up. The swell direction is from the WNW, which is perfect for this spot. This is a reef break, and that long period (10 seconds) will bring proper, well-shaped waves. It’s an advanced break, so keep that in mind. The crowds are sometimes an issue here, so get in early. The afternoon also holds up with 5ft and glassy conditions, but the morning is the pick.
After that, we drop back into junk. The rest of the second week is a mix of tiny, onshore, and choppy slop. The 15th and 16th bring some size again, but the wind is consistently cross-onshore, ruining the shape. That Sunday the 9th is your one and only shot at something special this forecast period.
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.
