Trestrignel Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s on offer at Trestrignel. We’ve got a real mixed bag ahead, but a couple of sessions are truly worth circling on the calendar.

The next week and a half is looking pretty grim for a paddle. Most days are a write-off—either the wind’s in the wrong place or the swell is all messy cross-chop. You’ll be fighting a strong cross-shore or onshore wind for most of it, and the surf quality just isn’t there. The water is sitting at 67°, which is a touch warmer than you’d expect for late summer. There’s a long stretch here from the end of August right through most of the first week of September where you might as well leave the board at home. There is no real standout surf until we get past the first week.

The first real glimmer of hope comes on the morning of Saturday, 5th September. It’s not a classic, but with a 6ft west-northwest groundswell and a light southwesterly cross-offshore breeze, the surf will be clean. The combined swell energy is moderate at 550, and the 10-second period will give you some reasonable shape. It’s the best of a bad run, but it’s not going to blow your mind.

Now, the real standout, the one you’ve been waiting for, arrives on Friday, 11th September. The morning session is the clear winner of the entire outlook – this is the one to chase. We’re looking at a solid 7ft swell from the west, with a 9-second period. But the key here is a light, steady cross-offshore wind from the east-southeast. That’s going to keep the surface absolutely clean. The combined wave energy is strong at 1318, so there’s plenty of power behind it. It’s going to be one of those mornings where the banks line up. It’s worth noting that with 7ft, this is expert territory, but the offshore wind will help make the walls stand up. Trestrignel is a sheltered spot, and this swell direction (W) matches what the place loves to see. Expect the weekend crowd to be a problem here, as it’s *always* busy, but for a clean 7ft morning, you fight for your waves. The afternoon sees the swell bump up to 8ft and the period extending to a very long 13 seconds, but the wind flips to a moderate cross-shore, which will bring chop. The morning is your window.

Following that, the morning of Saturday, 12th September still has some juice in the tank. A 6ft west-northwest swell with a 11-second period and light cross-offshore winds will provide another clean, fun session, though not as heavy as the day before. The wave energy is a solid 694. It’s a good capper to the week’s highlight.

After that, the energy drops off quickly into the second week. We see a glassy 4ft on the morning of Sunday, 13th September, but the period is shorter and the energy is lower (391). It’s surfable but ordinary.

So, to sum it up: you’re looking at a lot of flat and messy conditions until the morning of Saturday, 5th September, which is a minor reprieve. The absolute standout is the morning of Friday, 11th September. Get organised, watch the buoys, and be ready for it. The second weekend shows some promise, but it’s less certain this far out. Don’t hold your breath for the rest.

Rusty.
