Trestrignel Surf Forecast and Surf Report

Hey folks, Rusty here. Let’s have a look at what’s on offer for Trestrignel over the next couple of weeks.

Right off the bat, I’ve gotta be straight with you – this isn’t a classic run for Trestrignel. The first solid chance we get doesn’t show up until Saturday morning, the 5th of September. We’re looking at a 6ft swell out of the WNW, with a period of 12 seconds, carrying a decent amount of energy (797). That’s a bit of a groundswell, and it’ll be breaking with some push. But the wind is onshore from the NNW at 3 mph, and the water temp is sitting at 64°, which is about average for this time of year. The comments call it marginal, and honestly, the onshore breeze will mess with the face. It’s not a total write-off for a beginner wanting a splash, but it’s not clean.

Saturday afternoon gets worse – the wind picks up to 9 mph from the NNE, cross-onshore, and the swell drops to 5ft. That’s a no-go.

Sunday morning, the 6th, is where it starts to get interesting. We’ve got a 3ft swell from the WNW, period 10 seconds, and the wind swings to SSE at 12 mph – that’s offshore. The energy is low (166), but that offshore wind will clean it right up. For a smaller board or a longboard, this could be a fun little session. The comments say “surfable waves but very ordinary conditions,” but with offshore wind, it’s better than that sounds. The morning is the window.

The standout, though, is Monday the 7th – but only if you’re an expert. The swell jumps to 6ft in the morning and 6ft in the afternoon, from the W and WNW, with periods of 14 and 13 seconds. That’s real groundswell, and the energy is big (1047 and 1154). But the wind is cross-onshore from the W and WNW at 12 mph, and the comments are clear: “poor surf conditions.” For a beach break like Trestrignel, that cross-onshore wind will chop it up. At 6ft, it’s too big for beginners, and the wind spoils it for everyone. Honestly, this setup might be more interesting for kite surfing than paddle surfing.

The rest of the first week and into the second is a real slog. From Tuesday the 8th through to Sunday the 13th of September, it’s a mix of cross-onshore winds, lumpy conditions, and dropping swell. The energy drops from 716 down to 175. There’s a moment on Thursday the 10th morning with cross-offshore wind from the SW at 19 mph, and 4ft swell, but the comments are still “poor surf conditions.” The wind is strong, and the swell is weak.

Now, after a long gap of poor options, we get a flash of something on Tuesday the 15th of September. The morning is glassy – wind from the E at 0 mph – with a 4ft swell from the ENE. The period is short, only 5 seconds, so it’s weak energy (140). But it’s glassy. That’s a rare moment of clean, small waves. It’s surfable, but very ordinary. For a quiet morning on a log, it’s your best bet in the second week.

The rest of the run up to the 20th of September is a steady diet of cross-onshore winds, choppy seas, and tiny swell. Don’t get your hopes up.

Bottom line: The best bet is Sunday morning, the 6th of September, with offshore wind and a clean, small swell. It’s not a big day, but it’s the cleanest. For experts, Monday the 7th has the size, but the wind ruins it. The glassy morning on Tuesday the 15th is a small, clean novelty. Everything else is a skip.

Stay patient, and keep an eye on the forecasts.

Rusty.
