The Lowdown

Alright, Rusty here. Let’s talk about what’s on the menu for Mullaghmore.

First off, I gotta be straight with you – this is a tough one. The whole 16-day window is looking pretty flat and messy. We’ve got a lot of days with onshore winds and small, weak swell. The energy is just not there, with most days showing combined swell energy in the weak range (under 100). There’s a big gap of poor conditions from the start all the way through to the end.

Let’s start with the water temp. With the water at 61°F, that’s a touch warmer than normal for this time of year, so you might not need the thickest wetsuit, but you’ll still want a good one.

The first few days, from Tuesday the 28th of July through to the end of the first week, are all a write-off. Swell is tiny, mostly under 4ft, and the wind is cross or cross-onshore from the west and northwest. The period is short, around 7-8 seconds, so it’s just wind slop. The combined energy is weak, peaking at 198 on Tuesday afternoon, but the wave comment says it all – “poor surf conditions.” Not worth the paddle out.

We get a little glimmer of hope on the 7th of August, Friday morning. The wind goes glassy, which is a major positive. The swell is only 3ft to 3ft from the northwest, with a period of just 5-6 seconds. It’s small and weak (combined energy 42-79), but if the wind is truly glassy, you might find a few fun, clean little waves. It’s the only time in the whole forecast where the wind is perfect, so if you’re desperate, that’s your one shot.

The rest of the second week, from the 8th of August onward, is a total bust. The swell drops to 2ft and below, and the wind is howling from the south and southwest, sometimes over 25 mph. The combined energy is pitiful, often under 50. It’s not even worth looking at the water.

The standout, if you can call it that, is the morning of the 7th of August. The glassy wind is the only real positive. The break is a reef, and with the wind off, it could be clean, but the swell is too small and weak to get excited about. For the vast majority of this period, the setup looks more interesting for kiting than paddling, with strong winds and small, choppy surf.

Overall, it’s a very long, flat, and windy stretch. Don’t hold your breath.

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.
