The Lowdown

Alright, Rusty here. Let's have a look at what's coming down the line.

Alright, let's be straight with you. The outlook for the next 16 days at Mullaghmore is a real mixed bag, and to be honest, mostly a frustrating one. The water temp is sitting at 62°F, which is a touch warmer than normal for this time of year, but that's about the only thing that's feeling summery.

We kick off with a big, angry pulse of swell on Friday the 4th of September. We're looking at 12ft of swell from the West, with a period of 12 seconds. That's a lot of energy, but it's a total write-off. The wind is honking from the West at 28 mph, smashing it sideways. It's a cross-onshore mess. Not a paddle in sight.

That big swell drops through the weekend, but the wind stays mean. Saturday the 5th sees the swell drop to 6ft, but it's still cross and lumpy. By Saturday afternoon, the wind lightens up, and conditions do get clean, but that swell has dropped to a tiny 4ft. It's surfable, but very ordinary. Sunday the 6th is a complete write-off with strong winds and a tiny, weak swell.

The following week is a tale of missed opportunities. There's plenty of swell, but the wind just won't play ball. On Monday the 7th, we see a 6ft West swell, but it's messy. Tuesday the 8th brings another 12ft pulse from the West, but again, it's getting hammered by strong cross-onshore winds. This is a setup that looks far more interesting for kite surfing than paddle surfing. It's just relentless.

The only real glimmer of hope arrives on Saturday the 12th of September. This is our standout. The wind drops right out, with a light SSW breeze at 3 mph. The conditions are clean. The swell is a respectable 5ft from the WNW with an 11-second period. The forecast is for "expect good surf conditions". This is the one to wait for. It's a point break and reef, so that longer period swell will wrap in nicely. Keep in mind, crowds are possible here.

After that, the swell goes quiet again. We get a bit of a clean-up on Sunday the 13th with offshore winds and a 3ft swell, but it's small. There's a long gap with very little surf on offer, just small, choppy waves until the very end of the outlook. The last few days starting around the 17th and 18th of September start to see some size come back, with a 8ft West swell on the 18th, but by then it's back to cross-onshore winds. It's a tough run.

So, to sum it up: the best bet by a long shot is Saturday the 12th of September. Everything else is a fight against the wind or just too small. The spot is fairly consistent, so it tends not to stay poor for long, but this is a pretty blank run for the area.

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.
