The Lowdown
Alright, folks, Rusty here. Let’s take a deep dive into what we’ve got coming up at Pors Ar Ville.
Right off the bat, don’t get your hopes up for the first few days. We’re looking at a slow start, with not much to write home about. The first real sniff of something decent doesn’t show up until the morning of Sunday the 13th.
So, Sunday morning the 13th is where we see our first proper window. The swell is a clean 5ft out of the WNW with a solid 11-second period pushing through, giving you some decent energy in the water (moderate at 452). What makes this one the standout for the early window is that glassy offshore wind from the WSW. It’ll be clean and lined up, making it the best bet for the first week.
Monday the 14th drops back off with a smaller swell and onshore junk, so we’re back in the waiting room.
As we push into the second week, things get more interesting, but they also get less certain. The morning of Friday the 18th is a real highlight. We’ve got 6ft of solid WNW groundswell, with a period ticking up to 10 seconds and a heap of energy behind it (763 – moderate to strong). A gentle offshore breeze keeps it glassy. This is the pick of the first week into the second. The afternoon holds similar size with a longer 13-second period and massive energy (932), the only caveat being the wind swings a bit cross-off.
Now, for the brave and the bold, the morning of Monday the 21st is a big one. That’s over a week and a half out, so treat it as promising but not locked in. If it hits, we’re talking a solid 8ft of NW swell with a 13-second period and a colossal 2140 on the energy scale – that’s serious power. The wind is offshore from the SW, but honest to god, at that size, only the experts are going to want to paddle out. This is proper, heavy stuff and better suited to the experienced crew.
Another big shout goes to Tuesday the 22nd morning. You’re looking at 6ft of WNW groundswell, 12-second period, and excellent conditions with a light breeze. Great energy (1056). That’s another session to keep a very close eye on.
By the 23rd and 24th, the wind clocks around to the east and onshore, trashing the quality, and the swell fades through the end of the period. The 27th shows another pulse of long-period NW power (16 seconds!) but with strong cross-off winds; it looks powerful but not super clean.
That Sunday the 13th morning is your best early call. For the second week, keep an eye on Friday the 18th morning, and brace yourself for Monday the 21st if you’ve got the skill.
