The Lowdown
Alright, Rusty here. Let me talk you through what's on the cards for the next little while at Pors Ar Ville.
The next few days are looking pretty ordinary to be honest. We've got a bit of a wait on our hands before anything really clicks into place. There's a noticeable gap of clean, rideable surf until around Friday the 18th of September.
Kicking off Monday the 14th and Tuesday the 15th, we’re looking at small, weak swell. It's hanging around 3 ft to 3 ft from the WNW with a period of just 8 to 9 seconds. The wave energy is weak (around 137 to 149). Cross-off winds will keep the surface clean enough, but there's just no push or power. Not worth paddling out for.
Wednesday the 16th gets a bit bigger, with the swell jumping to 7 ft, but it’s a cross-on wind and a bit of chop on it. The energy picks up (766), but the quality is still poor. Thursday the 17th stays similar, with 5 ft to 6 ft and cross-off winds, but the wave comment is still not good.
Alright, now we’re talking. Friday the 18th of September is the real standout in this forecast. The morning brings a solid 7 ft groundswell from the WNW, and the period stretches out to a very long 13 seconds. The energy jumps right up (1673). Winds are cross-off and clean. This is proper groundswell, so it’ll have plenty of punch and those long waits between sets. With that big period, it'll be best for the reefs and points, and less ideal for the beach breaks. It's big too – over 8 ft – so this is strictly for experienced surfers. The afternoon holds at 7 ft with similar quality.
Saturday the 19th and Sunday the 20th drop back a bit. Saturday is still clean with 5 ft and a 12-second period (560 energy), but it’s dropping. Sunday morning, the 20th, is worth a look though: 5 ft from the WNW with a 10-second period, and we finally see some true offshore wind from the WSW at 6 mph. The wave comment picks up to "expect good surf conditions". That offshore wind will make it glassy and clean. This is a good session for the intermediate crew. Crowds are said to be only *sometimes*, so you might get some space.
The following week, from the 21st on, we fade out fast. Swell drops below 3 ft, winds turn cross-on or onshore, and the energy tanks. By the 23rd of September we're down to pure onshore junk. The final days of September and into the 29th are forgettable – small, choppy, and weak. It’s a classic late-season wind swell fade-out.
So, bottom line: hang tight, get out on Friday the 18th if you’re an expert, and Sunday the 20th morning for the cleaner, smaller stuff. After that, the surf goes quiet for a stretch.
Rusty.
