The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Pors Ar Ville.
To be straight with you, the next week and a half is mostly a write-off. We’re looking at a long, quiet stretch from now until the end of August. There’s just nothing doing. The swell is tiny, or the wind is all wrong, or both. You’ll be staring at flat, lumpy water for days. It’s one of those patches where the ocean seems to have forgotten how to make a wave. Don’t bother checking the forecast every morning; you’ll just get bummed out.
Then, things finally start to look interesting as we head into September. There’s a real glimmer of hope for the 4th of September. On Friday morning, the swell bumps up to 5ft, straight out of the WNW. The combined energy is moderate (380), so there’s some proper push behind it. The wind is light from the north, which is cross-on, but with that light breeze, it’ll only have small wind ripples. It’s not perfect, but it’s the first time in ages you’ll feel some real power. Keep an eye on that afternoon too, with 5ft swells still running.
But the real standout, the one you’ve been waiting for, is Saturday the 5th of September. Mark it in your calendar. We’ve got a 5ft swell from the WNW, with a 12-second period. That’s proper groundswell, banking in with longer, more powerful sets. The combined energy is a strong 668, so you’ll feel that deep water pulse. And the wind? Offshore. A light breeze from the southwest. That means Pors Ar Ville will be clean—glassy, rippable walls. This is the session to aim for. The waves will be big enough for the advanced crew to get stuck into, but the period is long, so it might wall up a bit on the beach; the reef and river area should handle it beautifully. Keep in mind, this is a week and a half away, so take it as a promising outlook, but don’t book the day off work just yet.
Overall, the water temp will feel about average for this time of year. So, endure the flat spell, and get ready for that first weekend of September.
Rusty.
