The Lowdown
Alright, Rusty here again. Lookin’ at the same stretch for Mullaghmore, and the story’s the same, just in feet. It’s gonna be a tough run. This is a proper reef, sheltered from the north-west, but the next couple of weeks are lookin’ pretty lean and messy. The mix of small waves and dodgy wind will make it hard to get a decent session. The water’s a touch warmer than usual for this time of year, sittin’ at about 61°F.
We start on Monday the 10th with a glassy 2-foot swell from the WNW, but it’s weak, only 61 (combined energy) and a 8-second period. Poor conditions, honestly. Not worth paddlin’ out. Tuesday the 11th is tiny – 1-foot to 0.7-foot – and even with clean offshore winds, there’s just nothin’ to ride.
The whole first week, from the 10th right through to the 19th, is a write-off. That’s a solid 10-day gap with barely a wave worth talkin’ about. Swell heights hang around 0.7-foot to 4-foot, and when it does bump up a bit, the wind’s cross-on or onshore, turnin’ it into a choppy mess. Thursday the 20th shows a pulse of 5-foot from the west with a 10-second period, and the energy jumps to 509 (combined energy), but it’s onshore and labelled as marginal. You’d be fightin’ the wind more than the wave.
The real standout – and I mean the only one – is Tuesday the 25th of August. That’s over a week away, so take it with a grain of salt, but it’s lookin’ promising. We’ve got a clean, 7-foot swell rollin’ in from the west with a solid 10-second period. The wind’s light, offshore from the south, and the combined energy is pumpin’ at 834 (combined energy). This is a big boy swell, over 5-foot, so beginners should sit this one out; it’s for the experienced crew only. That north-west swell direction isn’t perfect for this sheltered spot, the optimum is NW, but a clean 7-foot on a reef is gonna produce some proper, thick walls. Crowds are possible here, so be ready to share. That Tuesday morning is your window.
The afternoon on the 25th drops to the same size but onshore wind changes it up, so nail the morning. Before that, there’s a long, dry spell. Don’t hold your breath for the rest of it.
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.
