Trestrignel Surf Forecast and Surf Report

Alright, Rusty here. Let's be straight up about Trestrignel for the next couple of weeks. The outlook is pretty bleak for surfers, with a whole lot of grovelly, wind-affected junk and not much to get excited about. The first real glimmer of anything semi-decent doesn't show up for a while, so we're looking at a long stretch of poor conditions.

The water is sitting at about 65°, which is a touch warmer than normal for this time of year, so that's one small consolation if you're just having a splash.

The whole first week, from Monday the 14th right through to Friday the 18th of September, is a write-off. We've got increasing wind and messy, onshore slop. The swell does build, hitting a peak around Wednesday the 16th with a 7ft cross-onshore wind swell that’s got some moderate to strong energy in it (947), but it’s completely unsurfable with that NW wind tearing it apart. It’s the kind of setup that might look more interesting for a kite surfer than a paddle surfer.

We finally get a tiny window of cleaner surf on the morning of Saturday the 19th of September. The wind swings to a cross-off shore from the SW, with a 5ft, 12-second swell from the west. The energy is moderate (546), and it’s described as clean. The score is a ‘marginal’ 1 out of 10, but it's the best we've seen. The waves will still be very ordinary, but at least the wind isn't ruining it completely. It’s a beginner-level spot to begin with, and the crowds are always a factor here, so don't expect any peace.

Then it goes back downhill Saturday afternoon. The next real standout is Sunday morning, the 20th of September. The wind goes completely glassy, with 5ft of WNW swell. It's a glassy ocean, which is a major positive for clean conditions, but the waves are still described as very ordinary. Again, the energy is moderate (363). It might be worth a paddle for a few small, clean waves if you're desperate.

The only other blip of hope is a cleaner session on the morning of Monday the 21st of September. We get a cross-offshore E wind, a 4ft, 13-second swell from the WNW (moderate energy at 543), and the forecast actually says "expect good surf conditions." This is the best call of the whole period, but at Trestrignel with a shorebreak beach setup, that long 13-second period can make the waves a bit too straight for good shape. Still, with clean winds, it’s worth a look.

After that, the system just dies. From the 22nd onward, it’s all small, weak, and mostly cross-shore junk. Even the cleaner cross-off days on the 24th, 25th, and 29th have either no swell or a tiny, weak short-period wind swell. It’s a long, quiet end to the forecast.

So, the short story: don't hold your breath. The one and only standout in this whole 16-day window is the Monday morning session on the 21st of September, with clean conditions and that 13-second groundswell. The Sunday glass-off on the 20th is a very distant second.
