The Lowdown
Alright, Rusty here, letting you know the score for Trestrignel. It's been a flat and messy run, and honestly, it stays that way for a good long while. We're looking at a big gap of quiet water.
The first week is pretty much a write-off. From Tuesday, August 11th, right through to the evening of Thursday, August 20th, the surf is no good. Tiny, weak waves with nothing but cross-shore or onshore wind. The energy is low, reading anywhere from (47) to (226), which just isn't enough to get excited about. It’s a whole lot of nothing for nine straight days.
Friday, August 21st, shows a tiny flicker. The morning goes glassy with a light offshore – that's an ENE breeze at just 3 mph, which is a beautiful thing for the surface. There's a little 4ft WNW groundswell pushing in with a moderate energy of (218). The period is 10 seconds, so not world class, but it's a clean window on a normally crowded beach. You might find a few knee-high walls to yourself if you beat the locals, but just know the afternoon goes to junk again.
Then, hold onto your board, because Saturday, August 22nd, is the real standout. A chunky 12ft WNW swell rolls in with a lot of power, reading a very strong (3248). The period is a solid 11 seconds. Now, this is big – over 8ft, so expert territory only. It's coming from the WNW, not the optimal NW for this sheltered spot, but it'll still push in. Morning has a cross-shore wind, keeping things from being perfect, but the raw size is undeniable for the heavy crew.
The next day, Sunday the 23rd, the swell drops fast to 7ft, but the cross-shore wind is still fresh at 16 mph and the surface is lumpy. Still a big, powerful day for the experienced.
Looking further out, Monday August 24th brings a clean morning with a cross-offshore wind, but the swell is tiny again at just 2ft. It's a long-period groundswell at 14 seconds, so there are long waits between sets, and it might be too straight for the beach, but it’s a clean, empty morning for a log.
Honestly, the best you're looking at in this 16-day window is that Saturday the 22nd. It’s the one legit size day for experts. Everything else is small, windy, or both. The water temp is about average for this time of year, so no wetsuit drama there.
Stay patient, but keep an eye on that 22nd.
Rusty.
