The Lowdown
Alright folks, Rusty here with a look at what’s cookin’ for the next couple of weeks.
To be brutally honest, the next week and a half is a bit of a write-off. We’re looking at a long stretch of weak, chopped-up slop with cold onshore winds. From Wednesday the 19th right through to Saturday the 29th of August, it’s just poor surf conditions day after day. The swell is tiny, the wind is all over the shop, and any energy in the water is getting torn to bits. You’d be better off waxing your longboard and staring at it.
The real story here, and the only thing worth getting even a little amped about, is a pulse of proper groundswell that’s due to push in at the very end of the month. Mark your calendars for Sunday the 30th of August. Mullaghmore (Sligo) is the only break that matters, and it suddenly looks like a completely different ocean. We’re talking a solid 8ft to 8ft swell pouring in from the west with a long, powerful 12-second period. The combined wave energy is monstrous at 1544, and the direction is a proper match for this exposed reef. That said, it’s onshore wind straight at it, so it’ll be a raw, heavy, foamy beast. Think big, dangerous, grindy barrels for experts only. This is advanced terrain and only for those who know what they’re doing out there.
Monday the 31st of August hangs in there with a similar but slightly smaller 7ft west swell and a fresh onshore breeze. It’ll still be a heavy wave but wind-raked.
The water temperature is doing its own thing, but nothing too weird from the norm for the time of year.
So there you have it. A whole lot of nothing for a week and a half, then a sudden, heavy, expert-only session to end the month. The call is a long way out, so treat that last week of August like a promise from the weather gods – nice to hear, but don’t book the time off work just yet.
Keep your eyes on the horizon.

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.
