The Lowdown
Alright folks, Rusty here. Let's have a look at what’s shaping up for Pors Ar Ville over the next couple of weeks.
The window starts off a bit shaky, but there's a real gem hidden in there. The standout by a long shot is the Saturday morning (5th September) session. We’ve got a solid 6 ft of groundswell rolling in from the WNW with a long, juicy 12-second period. The combined energy is a solid 808, so there’s plenty of punch in the water. But the real magic is that wind – it’s swinging around to the NE at just 3 mph and going glassy. That’s as clean as it gets. For an advanced crew, this is the one to circle. The water is sitting at 65°, which is a touch warmer than normal for this time of year, so you might get away with a thinner suit.
The rest of the weekend is a bit of a mixed bag. Saturday afternoon turns onshore and messy, so don't get caught out late. Sunday (6th September) drops right off with weak 3 ft swell and only 151 energy, so it’s a day to sleep in or fix your dings. Monday morning (7th September) sees a pulse back up to 5 ft with a long 13-second period and moderate energy (892), but the cross-offshore wind keeps it a little tricky.
The following days are a real struggle. From the 8th through the 10th, there’s always some swell on the cards, but the wind is mostly cross-off or just plain messy, and the quality is poor. Thursday afternoon (10th September) does push back up to 7 ft with 595 energy, but the wind is a messy cross-off again, making it a gamble for the experienced lads only.
Then we hit a proper flat spell. From the 11th of September all the way through to the 14th, it’s tiny, weak, and blown out. The energy drops to triple and even double digits. It’s pretty grim.
We get a little bump in size from the 17th onwards, with swell sitting around 6 ft to 6 ft, but the wind is howling onshore from the NE and NNE at 15 to 22 mph. Combined energy climbs back up into the 500-700 range, but with that wind, it’s going to be a washing machine. At a beach and reef setup like this, it’s looking more like a kite session than a paddle session for that last stretch.
So, to wrap it up: the only true standout is that Saturday morning (5th September) glass-off. Everything else is either small, windy, or a bit of a slog. The long-range stuff in the second week is promising in size but is going to be a battle against the wind. Keep an eye on it, but don't hold your breath.
Rusty.
