The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this 16-day window for the region is a tough one. We’re looking at a long stretch of small, weak, and messy conditions, so you’ll need to be patient and pick your moments carefully.

The first real opportunity doesn’t show up until Friday the 24th of July, but even then, it’s a struggle. The morning swell is a weak 3ft from the WNW, with a messy 9-second period and combined wave energy sitting at just 132 (moderate). On top of that, we’ve got a moderate cross-onshore breeze from the WSW, making things choppy. The afternoon is a bit more of the same, with the swell pushing to 3ft, energy up to 144, but still a choppy cross-onshore wind. It’s not great, but it’s the start of the run.

We get a bit of a pulse on Saturday the 25th of July, with the swell jumping to 6ft from the WNW and a 9-second period. The combined energy hits 517 (strong), but the wind is a fresh cross-shore from the WSW at 19 mph, making it lumpy. This is more of a kite-surfing day than a clean paddle session. Sunday the 26th stays similar, with 5ft to 6ft swells and energy in the 400-600 range, but the cross-onshore wind keeps it choppy and messy.

The standout, if you can call it that, is a bit of a long shot but it’s the best we’ve got. Look towards the end of the month, specifically Thursday the 30th of July and Friday the 31st. The morning of the 30th, the swell drops to 2ft from the WNW, but we get a clean cross-offshore breeze from the ESE. That’s the first time we see anything close to clean. The energy is weak at 48, but it’s glassy. The afternoon of the 30th sees a moderate offshore wind from the ESE, keeping it clean, but the swell is still only 2ft.

The real highlight is Friday the 31st of July. The morning brings a 3ft swell from the west with a longer 11-second period, which means better shape. Combined energy is a solid 247 (moderate), and we have a clean cross-offshore wind from the ESE at 19 mph. The afternoon is offshore from the SE, still 3ft from the west, with energy at 210. That’s your best window: clean, lined-up waves, but it’s still nothing massive. The water temperature is about average for the time of year, so no surprises there.

After that, the swell fades again into early August, with tiny 1.0ft to 2ft waves and mixed winds. The 1st of August has a gentle offshore in the morning, but the swell is only 2ft, and by the afternoon it’s a light cross-shore. The gap from the 31st of July to the end of the forecast is mostly flat or small.

So, for the best on offer, it’s Friday the 31st of July. The swell direction from the west is a decent match for the optimum, and the near-offshore wind will give you some clean faces. It’s not a big day, but it’s the only one that looks like a proper surf. Keep your expectations in check, and if you’re a beginner, the 2ft days on the 30th and 31st are safe, but the 3ft on the 31st is fine for intermediates. Anything over 5ft on the 25th and 26th is getting too big for beginners, and the wind is a mess.

That’s the long and short of it. Conditions are tough, but there’s a tiny window of clean, rideable waves at the end of the month. Stay sharp.

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.
