Trestrignel Surf Forecast and Surf Report

Alright folks, Rusty here, and we’ve got a bit of a mixed bag on our hands for Trestrignel. The first few days are going to be pretty ordinary, so don’t get your hopes up early. There's some swell around, but the wind just won't play nice, keeping things choppy and messy. We do have a glimmer of hope later on, but you’ve got to be patient.

The real story here is the water temp. It’s sitting at 65°F, which is a touch warmer than normal for this time of year, so you can probably get away with a thinner suit or even just a springsuit if you’re tough.

Looking at the immediate forecast, Friday the 11th through Sunday the 13th is a write-off. We’ve got swell in the 3ft to 5ft range, but the wind is cross or cross-on all day, every day, churning it up into a bumpy mess. The combined energy is moderate, hitting values around 470, but it doesn't matter when the surface is that ugly.

Monday the 14th morning is our first real chance. The wind goes light offshore from the south, cleaning things right up. Swell is small, only 3ft from the west with a 9-second period, and the energy is weak (169). It’s surfable, but only just. You'll be scratching for waves, but it’ll be clean.

Tuesday the 15th gets ugly again with strong onshore winds, and by Wednesday the 16th we have a bigger, but totally blown-out, 8ft swell. That’s a strong energy event (1011), but with a fresh onshore wind, it's just a washing machine. Best left for the kite surfers, not a paddle session.

Thursday the 17th and Friday the 18th are still messy with cross-onshore wind. Friday the 18th morning has a decent 5ft groundswell with a long 12-second period, and the energy is moderate (579), but that cross-onshore breeze is going to put a lip on it.

Now, we get into a more interesting pattern starting Saturday the 19th. We get clean, cross-offshore winds for a few days. The swell stays small, between 3ft and 4ft, and the period is solid (10-11 seconds). The energy is moderate, around 260-330. It’s not pumping, but it will be clean and rideable. This is your window for a longboard or a funboard.

Monday the 21st afternoon is a standout moment. The wind goes dead calm – glassy conditions. The swell is 4ft from the WNW with an 11-second period, and the energy is moderate (312). This will be the cleanest, most pleasant session of the whole stretch. Crowds are inevitable at Trestrignel, so get out early for that glass.

The forecast gets a bit wild and less certain further out. Tuesday the 22nd and Wednesday the 23rd are blown out again by strong winds, with Wednesday the 23rd seeing a very long period (14-second) groundswell. It’s 4ft, but a screaming 25 mph offshore wind from the south will make it clean but incredibly difficult to paddle into. The energy is strong (633).

Finally, the last real highlight is on Friday the 25th of September. We see a 6ft swell from the WSW with a long 13-second period. The energy is very strong (1318), and the wind is cross-offshore. This is the best swell of the whole forecast. It’s a powerful groundswell that will hit the banks hard. For a beach break like Trestrignel, that long period can make it a bit straight, but with the right tide and that wind, there could be some proper walls. This one is for the experienced crew; it’ll be a bit much for beginners.

After that, the weekend of the 26th fades back into small, choppy conditions.

So, to wrap it up: don't bother until Monday the 14th morning, but keep your expectations low. The best bet for a clean, fun session is Monday the 21st afternoon for the glassy conditions. The biggest, most powerful swell of the period is Friday the 25th of September, but that’s a long way off and things can change. That one has real potential.

Rusty.
