The Lowdown
Alright, Rusty here. Let’s break down what we’re looking at for the next couple of weeks.
Honestly, mates, it’s a bit of a tough stretch. The first good week or so is pretty grim. Up until July 24th, we’re looking at a whole lot of nothing – tiny swells, poor directions, and wind that’s just not playing ball. There’s a real gap there with no real recommendations. Things start to pick up a little from the 24th, but it’s not until July 27th that we finally get a sniff of something worthwhile.
The water temp at Mullaghmore is running at 64°, which is a massive 6° warmer than normal for this time of year. That’s very unusual, so you’ll be in for a pleasant surprise if you’re used to freezing your bits off.
The standout window is July 27th, Monday afternoon. Mullaghmore is the only spot that finally gets a “marginal” call rather than a straight “poor”. We’ve got a 6 ft swell from the W, with a period of 10 seconds, generating moderate wave energy (609). The wind is a gentle breeze from the SSW, which is cross-offshore. That means the waves should be clean. This is a big, heavy reef break, so it’s only for experts. It’s fairly consistent here, but crowds are possible. With that cross-off wind, it’s your best bet in this whole 16-day window.
After that, July 28th looks like a write-off – a 10 ft swell from the WNW, but with a 25 mph cross-onshore wind. That’s a messy, blown-out mess. The 29th and 30th settle back into small, poor-condition surf. The first few days of August are tiny again, with nothing to get excited about. So, if you’re a local, pencil in the afternoon of the 27th, and keep an eye on the forecast for a lucky break. It’s a long quiet spell before and after.
Rusty.

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.
