The Lowdown

Alright, this is a bit of a tough one for the regulars. I've been looking at what's on the cards for the next couple of weeks, and honestly, it's a flat spell with a whole lot of nothing. The only break that's even on the radar is Mullaghmore, a heavy reef setup that only the most experienced crew should be looking at, and even then, the conditions are going to be a battle.

We kick off on Monday, July 27th with a bit of a tease. There's a 4ft swell from the WNW with a 10-second period, giving us a combined energy of 346 (moderate), and the water is a touch warmer than normal at 62°. But the wind is a cross-off from the south at 9 mph, which is clean enough, but the overall score tells me it's just ordinary. The morning is the best of a bad bunch, but it's not good. By Monday afternoon, it's a total write-off with cross-on wind.

The rest of that first week is a disaster. Tuesday the 28th is a mess with strong cross-shore winds and a lumpy 5ft swell. Wednesday and Thursday see the swell drop into the dirt, barely breaking 2ft, all with onshore or cross-onshore chop. Friday the 31st through Sunday the 2nd of August is a complete flat spell, with swell heights down to 1ft and no energy. You'll be staring at a lake.

There's a glimmer on Sunday the 2nd of August morning with glassy conditions, but that's on a 1ft swell. It's not surfable. The run of poor, small waves continues right through the first week of August. We get a bit of a bump on Friday the 7th of August with a 3ft to 3ft WNW swell and a 9-second period, with clean cross-off winds. The combined energy creeps up to 146 (weak to moderate), but it's still a long way from being exciting.

The only real swell of the entire window shows up on Saturday the 8th of August. We're looking at a 6ft WNW swell with an 8-second period, and the combined energy jumps to 414 (moderate). That's the biggest swell of the 16 days. But here's the catch: the wind is a light cross-on, and the wave comment calls it marginal. For a spot like Mullaghmore, a 6ft, short-period swell with cross-on wind is a messy, dangerous, and probably unsurfable proposition. It's a big, lumpy, close-out machine. After that, the swell fades back into the 3ft range and the wind stays onshore, then goes glassy or offshore on the 10th and 11th, but on a tiny 3ft swell.

So, the bottom line? There's no standout. There's no good surf. The only break with any data is a maxed-out, expert-only reef that's going to be blown out on the only day with any real size. If you're a kite surfer, that Saturday the 8th might be a laugh, but for a paddle surfer, this is a two-week write-off. Hold tight, the forecasts can change, but right now, it's a bust.

Information about the Mullaghmore Surf forecast

The above surf forecast table for Mullaghmore provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mullaghmore can be found by selecting the local surf guide option on the grey menu. Our Mullaghmore surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Mullaghmore) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
