The Lowdown
Right, let’s have a proper look at what we’ve got on the horizon here at Poldhu Cove. It’s been a bit of a mixed bag, and to be honest, the first week or so looks pretty ordinary, so don’t be in a rush to grab your board just yet.
We’ve got some weak to moderate energy moving through for most of the first week, but the wind is the real problem. Tuesday the 8th sees a fresh NNW breeze making a mess of things. The swell is 6ft from the WNW, but that cross-off wind at 22 mph is just too strong for clean conditions. The water feels a touch warmer than normal for the time of year at 64°F, but that doesn’t help the surf quality. The combined wave energy is moderate (660), but honestly, the conditions are poor. It stays messy and onshore through the rest of that week and into the weekend. Wednesday the 9th offers a marginal chance in the morning with a cleaner look, but 6ft from the west with a moderate breeze isn’t going to set the world on fire. There’s a long gap here where the call is just to wait it out.
The real standout, the one that has me properly excited, is Saturday the 19th of September. That afternoon, the stars finally align. The wind drops right out with glassy conditions, and we get a clean 4ft swell pushing in from the west. This is a long-period groundswell at 11 seconds, which means it’ll have some proper shape and power, especially for a spot like this which is fairly exposed to that SW direction. The combined energy jumps to a moderate 378. After days of chop and wind, that afternoon session is going to feel like a gift. For a wave that’s inconsistent and usually needs a bit of luck, this is a true standout. Surfable waves but very ordinary conditions at other times that week, but this is the one to circle.
Looking further out to the 23rd of September, we see a big spike in energy with a very long 16-second period swell coming in from the west. The combined energy is strong (1004). That’s a lot of water moving. With an offshore NNE breeze in the morning at 12 mph, it’ll be clean. But be warned – at 5ft, this is a powerful, long-period groundswell, and that can make beach breaks close out. At Poldhu Cove, which can be a bit fickle, it might offer some proper shaped lines, but it could also be a bit tricky. This is one for the experienced crew, but it’s a promising long-range call. The afternoon turns a bit more cross-off, so get it early.
