The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for the Mullaghmore region over the next couple of weeks.

Honestly, it's a bit of a grim start. We're looking at a solid stretch of nothing. From now until the end of August, the waves are just not doing their thing. The energy is low, mostly under 100 (weak), and the swell is tiny. There’s a few glassy moments, like Monday afternoon with a 4ft swell from the west and a perfectly still sea, but the surf is just too weak to get excited about. It’s a real bummer for a spot that can be so special.

That quiet spell stretches right through the first week of September. The water is a touch warmer than normal for this time of year at 62°, but that's about the only thing that's slightly out of the ordinary. We finally see a bit of life on the 2nd of September, but the wind is all wrong, coming from the west, making it cross-onshore and choppy. Even though the swell is up to 4ft with a moderate energy of 210, it’s not going to be any good.

The real change, and what might be the only standout, arrives on the 3rd of September. Thursday morning pulls in a clean 5ft swell from the west with a 10-second period, pushed by a strong cross-offshore wind from the SSE. The energy is solid at 426 (moderate). It's not massive, but it's clean and has some push. This is the best we’ve seen in a long time, and it’s worth a look if you're an experienced surfer. The afternoon sees the wind crank up to 34 mph, which is more of a howling mess for most, but the morning session is the one to aim for.

Then we get into the second week. The 5th of September is a bit of a wild card. Saturday morning has a 7ft swell from the west with a long 12-second period, and the energy is massive at 1532 (strong). The wind is cross-off and clean. That’s a lot of power, and for a reef break like Mullaghmore, that long-period groundswell can be a thing of beauty. However, it's getting into the "experts only" territory size-wise. The afternoon gets messy with cross-shore wind.

Looking further out, the 7th of September is a beast. Monday morning shows a 12ft swell from the west with a very long 17-second period. The energy reading is a whopping 6720 (very strong). That is a serious, heavy groundswell. This is the kind of day that will have the big wave chargers licking their lips, but for anyone else, it’s a hard pass. The wind is howling onshore, so it’s going to be a messy, dangerous mountain of water. The following days keep that energy up but with the same onshore wind problem, making it more of a spectacle than a surfable option.

So, to cut to the chase: the first week is a write-off. The best bet is the morning of the 3rd of September for a clean, solid wave. The 5th of September morning has the power but is for the brave. The 7th of September is a monster swell, but the wind will probably ruin it for most. Crowds at Mullaghmore are sometimes a problem, but on these days, with the conditions, you might find you have the place to yourself.

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.

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.
