The Lowdown

Alright folks, Rusty here. Let’s have a look at Mullaghmore for the next couple of weeks.

Straight up, I’m not gonna sugarcoat it: this outlook is a tough one. We’ve got a solid 16-day window ahead, but the surf is going to be a real challenge for the most part. The swell is there at times, but the wind is just not playing ball. There’s a big gap of days with no real standouts, so don’t get your hopes up for any kind of classic session.

We start off this Saturday the 25th of July. There’s some swell around, about 6ft to 6ft from the WNW, but it’s straight cross-on from the WSW and W, making for choppy, poor surf conditions. The combined wave energy is moderate (579 to 689), but the wind is ruining it. Sunday the 26th is more of the same, with a bit more size at 7ft, but the WNW wind is fresh and cross-on, so it’s lumpy and not worth a paddle. That’s all for the first weekend – a washout.

Now, Monday the 27th of July gives us a little glimmer. The size drops to 5ft from the W, but the wind goes light cross-off from the SSW. It’s clean, and the energy is moderate (377). This is probably the best we’ll see for a while, but it’s still a far cry from Mullaghmore’s potential. The wind is good, but the swell is small and the period is a short 10 seconds, so it won’t have that proper groundswell power. After that, we’re into a flat spell. From Tuesday the 28th right through to Wednesday the 5th of August, it’s all small, weak, and mostly wind-affected. Swell drops below 3ft, energy dips into double digits, and the wind is constantly on it or cross-on. There’s a glassy moment on the morning of Friday the 31st of July, but the swell is a tiny 2ft with a 7-second period – not enough to do anything with. Another glassy one on the morning of Monday the 3rd of August, but again, it’s 2ft and very weak. These are just flat, clean days.

Then, on Thursday the 6th of August, we get a little spike. Swell jumps to 4ft from the WNW, with a weak 7-second period. The combined energy is back up to moderate (169). The wind is light cross-on, so it’s messy, but for the first time in over a week, there’s a bit of push. Still, the cross-on wind and short period mean it’ll be choppy and won’t have that nice, walling shape Mullaghmore is known for. The rest of the second week, through to Sunday the 9th of August, fades back into small, weak, and poor conditions.

Honestly, the only real chance for a surf is that Monday the 27th of July, and even then, it’s for the die-hards. The swell direction is W, which is fine for Mullaghmore, but it’s not the ideal NW. The clean conditions are a positive, but the size and period just aren’t there. The rest of the window is a write-off for a proper paddle. This is a spot that needs a big, clean NW groundswell to shine, and we’re not getting that here. If you’re into kite surfing, those blustery, cross-on days with 6ft+ swell might look interesting, but for a surfboard, it’s a no-go.

Rusty.

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.
