The Lowdown
Imperial Version
Alright, folks, Rusty here. Let's have a look at what's cookin' up at Magheraroarty Strand.
Right off the bat, the very first chance we get for a surf is on Tuesday the 15th of September, but don’t get too excited. It’s a raw, poor situation with a strong wind from the WNW at 19 mph, making a mess of the 7 ft swell. The water is a touch warmer than normal for this time of year at 59°, but that's about all the good news. The combined energy is 784, so there is some power there, but it’s not workable.
Wednesday the 16th is interesting but frustrating. The swell jumps up to 8 ft from the WNW with a solid 11-second period—that’s proper groundswell energy at 1272. The forecast says "wind and tide favorable," but unfortunately, the swell is just too big for this break. A 31 mph wind on Thursday the 17th is pure madness with an 18 ft monster. That is expert-only territory, and even then the wind is horrendous. The energy reading of 10,985 is absolutely massive, but it’s a total write-off for surfing.
This pattern of massive, wind-affected swell continues right through the week and into the next. We've got 13 ft, 10 ft, all with strong, nasty winds. The energy levels are in the thousands, but the quality is zero for a standard surfer. It's all too big and blown out.
Now, if you’re looking for a real standout, you have to wait. The first genuinely decent window appears on the morning of Tuesday the 22nd of September. That’s a week away, so keep your hopes measured. Conditions look excellent with a gentle offshore breeze from the SSW. The swell will be a more manageable 6 ft from the west, and the energy is a moderate 880. This is a rare, inconsistent spot, so if it happens to be breaking, you’ll want to be on it.
The morning of Thursday the 25th of September is another promising call. We get a clean 6 ft swell from the north with a light offshore wind from the south. This spot is inconsistent and rarely shows up, so the fact that both Tuesday the 22nd and Thursday the 25th have potential is notable. Be there early, and you might score a clean wave with nobody around, as crowds are "never" a problem here.
After that, the surf looks to drop off towards the end of the month with onshore winds and weaker, shorter-period swell. The first week is a write-off due to size and wind. The real chance is that small window around the 22nd and the 25th. Set your alarm.
Rusty.
