The Lowdown
Alright, Rusty here, and I’m lookin’ at what we’ve got for Trestrignel over the next couple of weeks. Right off the bat, I gotta be straight with you – it’s a tough stretch. This spot is sheltered from the main swell, and for the next week and a half, the conditions are just a mess. We’re looking at a solid run of poor surf, with the wind and chop making things ugly. The water’s sitting at 65°, which is a touch warmer than normal for this time of year, but that’s little comfort when the waves are junk.
Starting Saturday the 12th, we’ve got weak 3ft swell from the west with a short 8-second period. The energy is low, just 147, and that cross-shore wind is gonna leave it bumpy. Sunday the 13th sees a bump in size to 5ft from the WNW, with moderate energy (521), but again, the cross-onshore wind chops it all up. This pattern just keeps repeating – Monday, Tuesday, Wednesday – all poor, with the wind never letting up. By Wednesday the 16th, we get a clean 5ft morning with the wind coming offshore at 16 mph, but it’s still only rated as poor surf conditions. The energy’s moderate at 432, but that’s not enough to save it.
There’s a real gap with nothing worth paddling out for until Sunday the 20th. That morning, the swell drops a bit to 5ft from the WNW, and the energy is back up to 469, but the wind is light cross-shore, and the report says the surf is only marginal. A light breeze with a long 13-second period swell on the 20th afternoon (497 energy) sounds tempting, but that cross-onshore wind’s gonna put a chop on it again.
The standout window? Honestly, there isn’t a true standout for Trestrignel in this forecast. The best chance to get wet might be Monday the 21st morning. We’ve got a 6ft swell from the WNW, a long 11-second period, and a solid 668 energy. The wind is a slight breeze from the WNW, which is cross-onshore but very light. It’s still called marginal due to tides or something, but it’s the biggest, most powerful swell of the whole run.
For the rest of the second week, the size totally fades. By Wednesday the 23rd, we’re down to ankle-biters of 2ft, and by Thursday the 24th, it’s a tiny 1.0ft. The wind goes clean and offshore on the 25th with glassy conditions, but with only 2ft of swell and a period of 10-11 seconds, it’s barely surfable. That’s a tease.
Overall, I’d say save your energy. The closest thing to a decent session is Monday morning the 21st, but don’t expect perfection. It’s been a poor run, and it’s not looking to get epic any time soon.
