The Lowdown
Alright folks, Rusty here. I've been staring at the charts for Trestrignel and, honestly, it's a bit of a tough one to call. There's no surf on the immediate horizon; we are looking at a two-week wait before things get interesting. The first hint of anything worthwhile doesn't show up until Thursday, 21st August.
Let's walk through it. The whole first week and a half is a write-off. From the 11th right through to the 20th of August, the conditions are consistently poor. We're seeing tiny swells, mostly under 3 feet, with cross-shore and onshore winds messing everything up. Energy levels are weak, with combined energy values stuck below 200 for most of it, often barely registering 50. The swell periods are short and unimpressive. It's just not worth paddling out. You’d be better off finding a lake.
Now, things finally start to flip around Friday the 21st of August. We get a bit of a pulse, and while the guidance calls it poor, the raw numbers tell a different story. Friday morning sees a 5.2ft swell from the WNW with a clean cross-offshore breeze from the East. The combined energy jumps to 220, which is a solid moderate level. That afternoon, it looks even better on paper: the swell pushes up to 5.9ft from the WNW with a clean side-offshore wind, and the energy ramps up to a powerful 510. The swell period is a short 7-8 seconds though, so expect a bit of a crumbly, less powerful wave. Still, it will be the best ride of the entire 16-day window, by a long shot.
Saturday the 22nd of August, however, is where the true stand-out lies. The swell builds to a solid 7.2ft from the WNW (combined energy of 778 – that's strong!), but the wind swings onshore from the West, making it choppy. At that size, with short period (9 seconds) and onshore wind, it will be a messy, powerful beast. This one is for experts only, and honestly, the wind might make it more of a spectacle than a surf session.
After that, it fades quickly into the weekend with dropping swells and lumpy conditions, before reverting back to flat and average by the 24th.
The Bottom Line: If you've got to get wet, your only real window is Thursday 21st August, with the afternoon looking the pick of the week for a clean, albeit short-period, 5.9ft wave. The 22nd is big and powerful, but a messy one for the experienced only.
