The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for Magheraroarty Strand.
We’ve got a bit of a mixed bag ahead. The first week is pretty grim, with a lot of onshore wind and junk surf, but there’s a real gem hiding in the middle of the forecast period. After that, it gets wild again, but you’ll have to wait.
Wednesday, August 19th kicks things off with a pulse of swell, but it’s not the day. The morning has a 7ft west swell at 10 seconds, which is a lot of juice for this spot, and the wind is a cross-offshore from the WSW. The wave energy is moderate (940). The size makes it a bit much for a beginner spot, but the wind keeps it clean. The afternoon drops to 6ft, but the wind goes cross-shore, making it less enticing. The rest of the week is a write-off. From Thursday the 20th right through to Sunday the 23rd, it’s onshore slop with building northerlies, dropping wave heights, and tiny periods. The water temperature is about average for this time of year. Honestly, it’s a complete blank run of about 5 days with nothing worth paddling for.
The standout is Monday, August 24th. This is the one to mark on the calendar. We’ve got a nice 7ft groundswell from the WNW with a long 11-second period, and the wind is light and offshore from the SSW in the morning. The wave energy is strong (891). This is a classic setup for a point break like this—clean faces, proper lines, and that long period means the sets will have some real push. The conditions are expected to be very good. Get out there early. The afternoon holds up at 6ft from the west with a cross-offshore breeze, still clean. This is by far the best surf on offer, hands down. After that, Tuesday the 25th drops to tiny 1ft leftovers, and we’re back to small, weak surf for the rest of the week.
Looking further ahead, Sunday, August 30th is a monster. The forecast shows a massive 10ft west swell with a 12-second period, and the combined wave energy is very strong (2180). It’s going to be huge. But here’s the catch: the wind is cross-shore, and the swell is simply too big for this break. The tide and wind conditions might be favorable, but the size means it’s only for the most experienced, and even then, it’s a serious beast. The Monday, August 31st, is also too big at 7ft with the wind turning onshore. After that, it drops off into the first week of September with small, clean, but weak surf.
So, the call is clear: Monday, August 24th is your best bet. Get on it.
Rusty.
