Pors Ar Ville Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for this stretch of coast.

Right off the bat, we’re looking at a bit of a flat spell to start things off. There’s nothing really worth paddling out for in the first couple of days. The first chance of any real waves comes Thursday the 3rd of September at Pors Ar Ville. It’s a beach and reef setup, exposed to the west-northwest. We’re seeing a 4ft swell rolling in from the west with an 8-second period, but that moderate breeze from the southwest is blowing offshore, keeping things clean enough. The water’s sitting at 65°F, which is pretty much what you’d expect for this time of year—nothing out of the ordinary there. The combined energy is weak (181), so don’t expect any fireworks. It’s surfable but pretty ordinary.

We then move into Friday the 4th. The swell picks up a touch to 5ft on Friday morning, still from the west-northwest, but that cross-off wind and a moderate energy reading (318) leave it feeling marginal. Friday afternoon gets a bit messy with a cross-shore breeze, so not the best window.

Now, the standout of this whole period looks like Saturday the 5th of September – the morning session. The swell holds at 6ft, but the period jumps to 12 seconds, and we get a light northeasterly blowing straight offshore. That’s a huge positive for clean conditions. The combined energy is ripping at 795 (moderate), and with that longer-period groundswell, the waves will have proper shape and power. Just keep in mind, with a 12-second period, this one will do better on the bank than it might at a beach break. This is the one to circle. The afternoon sees the wind pick up and the swell drop, so get on it early.

Sunday the 6th is a write-off—swell drops to 3ft by morning and keeps falling. Weak energy (152). Not worth it.

We get another pulse on Monday the 7th. Morning brings 4ft at 13 seconds (very long period), but the wind is a cross-off from the west-northwest. The combined energy is 514. It’s a solid window, though the forecast flags it as marginal. The afternoon bumps up to 6ft at 12 seconds with 887 energy—that’s a big, powerful groundswell. For experienced surfers, this could be excellent if you can find a bank that handles the long period. The wind stays cross-off, so it’s clean, but that 6ft is getting into expert territory.

Tuesday the 8th keeps the 7ft swell going in the morning with a 9-second period (603 energy), but it’s cross-off again. Stronger swell, but a shorter period means it might be a bit crumbly. Wednesday the 9th drops back down to 6ft with an 8-second period—still punchy but messy with a cross-shore breeze.

After that, we hit another lull from Thursday the 10th through to Saturday the 12th. The swell drops below 4ft and energy levels are weak to moderate at best. Not much to get excited about.

Then things get interesting again on Sunday the 13th of September – the morning. We get a 3ft swell from the northwest with a 12-second period, and a gentle offshore from the southwest with light breeze (9 mph). The combined energy is 321 (moderate). This is a classic clean, lined-up morning. Conditions should be glassy and the waves will be small but fun. The afternoon turns into a risk of thunderstorms with an onshore breeze, so the morning is the real window here.

Monday the 14th and Tuesday the 15th are poor—small, onshore winds, and even though Tuesday afternoon shows a 5ft swell from the northwest with a massive 16-second period and a combined energy of 1121 (very strong), the wind is onshore and choppy. That energy is wasted on messy conditions. For experts only, and even then, the wind kills it.

Wednesday the 16th shows 5ft from the northwest at 14 seconds (920 energy), but the wind is cross-onshore and light. It’s marginal at best.

Finally, Thursday the 17th of September – the morning—we get another clean window. 3ft at 11 seconds from the west-northwest, with a light cross-off breeze. The combined energy is 225 (weak), but the waves will be clean and fun for a grovel board.

After that, the swell just fades away into flatness for Friday the 18th and beyond. Nothing worth mentioning.

So, to wrap it up: if you’re chasing the best waves in this forecast, your two real standouts are the Saturday morning (5th September) – clean offshore, 6ft, 12-second groundswell with moderate energy; and the Monday morning (7th September) – big 6ft, 12-second groundswell with strong energy. The Saturday is the more all-round fun session, the Monday is for the more experienced crew.

As for crowds at Pors Ar Ville? The guidance says it can get busy sometimes, so don’t expect to have it to yourself on those better days.

Stay safe out there.

Rusty.
