The Lowdown
Right then, grab a coffee, here’s the outlook for Trestrignel.
We've got a long stretch ahead, and to be honest, for the first week or so it's pretty grim. The surf is on the small side or just plain messy, and that wind is going to be a constant battle. The real standout is a long way off, so we’re in a waiting game. The water temperature is sitting at 65°, which is a touch warmer than normal for this time of year at Trestrignel.
The first proper chance for anything decent doesn't show up until Wednesday the 23rd of September. That morning the winds go light offshore from the ESE, cleaning things right up. We’re looking at 4ft of swell from the WNW with a very long 13-second period, giving the waves proper energy (567 combined energy). It won’t be massive, but clean conditions and that groundswell should make for some fun, lined-up waves. This is the pick of the whole outlook, and it’s not huge, but for a break that’s been blown out for over a week, it's a welcome sight.
After that, there's another gap of a few days of small, clean but gutless surf. The big news, the one to really circle on your calendar, is Saturday the 26th of September. That morning we get a punchy 6ft groundswell from the west with a very long 17-second period, packing some serious energy (2016 combined energy). The winds are offshore from the east too. This is a proper, strong groundswell – the kind that will unload. It’s a bit of a caveat though; that long period might make it wall up and close out a bit at the beach, but on its day, Trestrignel can handle it. The size is in that fun-to-serious territory. Don't sleep on this one, but given it's over two weeks out, keep an eye on the charts. The rest of that last weekend and into the Monday offers clean but smaller, weaker leftovers.
In short, there is a lot of junk to sift through for one or two windows. The Wednesday the 23rd is your safe bet for clean, if not huge, waves. The Saturday the 26th is the one with the real potential to be something special, but it’s a long-range call, so fingers crossed.
