The Lowdown
Hey folks, Rusty here. Let's chew the fat on what's happening at Magheraroarty Strand for the next couple of weeks.
Straight off the bat, the first few days are a total blank. Tuesday the 15th is a mess with strong cross-shore wind and chopped-out, poor surf. Wednesday the 16th has some size, but it's predicted to be too powerful for this spot, with a cross-chop muddying it up. From Thursday the 17th all the way through the following weekend, the swell is just way too big for Magheraroarty. We're talking waves over 8ft and often much, much bigger, coupled with some serious wind. For a point break that's already inconsistent, this is not the time to be in the water. The wave energy numbers are huge, hitting four and five digits, but it's simply too much for a paddle session. Honestly, with that much swell and strong cross-off breeze mid-week, this looks more interesting for the kite crew than us.
Now, here's the session I've got my eye on. Look at Monday, September 22nd. The morning shows a 7ft swell from the WNW, which is just the right direction, and it rolls in with a very long 16-second period. This is heavy, deep ocean groundswell. The wind is light and cross-off, and the water temp is running a little warmer than normal for the season. The combined energy is 2,920 – proper power, but manageable. This is the real deal. The break is rarely consistent, so when it fires like this, you drop everything and go. You'll want some experience for that size and period, but it will be peeling and clean.
Later in the run, Wednesday the 25th of September is another day to keep free. The afternoon packs a 6ft swell from the WNW, but the standout is a monster 17-second period. The wind is light offshore from the SSW, promising silky, glassy faces. The combined energy of 2,095 tells you there's some serious grunt in the water. This is top-shelf stuff for experienced surfers – that long period will make the waves jack up and throw, a proper reward for those who can handle it. After that, the last days of September see the size jump back up, and it's likely too big again for this finicky spot.
So, to wrap it up: the first week is a write-off, but circle the 22nd and the 25th of September. Light wind, solid swell, and that raw, deep energy.
Rusty.
