The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Pors Ar Ville. It's a beach and reef setup, takes a solid WNW swell and is really one for the advanced crew.
The water's sitting at 64°, which is a touch warmer than we'd normally expect for this time of year.
Right now, it's a bit of a slow start. We've got a few days of nothing really happening. The first bit of interest comes on Wednesday the 16th, but it's not great. We're looking at a 7ft swell from the WNW, but the wind is cross, messing it up. The energy is building though, moderate at first then getting up there (632 and 794). It's marginal at best.
Thursday the 17th morning shapes up a bit better. The wind swings offshore from the WSW, cleaning things up. Swell is a solid 5ft from the WNW with moderate energy (373). It's a promising window, but still nothing to write home about.
Then we get to Friday the 18th. Now this is where it gets interesting. The swell bumps up to 7ft from the WNW, and the period stretches right out to 14 seconds – that's proper groundswell energy. The combined energy is pumping (1487). The wind is a light cross-off from the NW, so it should be clean. That 14-second period means it might be a bit straight at a beach break, but on a reef setup like this, it could be magic. This is the standout of the whole run. Saturday the 19th morning looks good again with a clean 4ft swell and offshore SW winds. Then Sunday the 20th morning, we get absolute glass – zero wind, clean conditions, and a 4ft WNW swell. A real treat for a quiet session.
After that, the surf drops off. From Monday the 21st right through to the end of the run on the 29th, it's pretty grim. Onshore winds, small waves, and poor conditions dominate. There are a few pulses of longer period swell late in the month, but the wind is just terrible, cross-onshore and lumpy. It's not worth getting excited about.
So, to wrap it up: the best bet is Friday the 18th. That 7ft groundswell with the long 14-second period and clean conditions is your winner. Sunday the 20th morning is also a cracker if you want some glassy waves. Everything else is a wait-and-see, but the second week looks like a write-off.
Rusty.
