The Lowdown
Right then, let's have a look at what's coming up for Sennen Cove.
To be brutally honest, the next week and a half is a bit of a write-off. We're looking at a long stretch from August 14th all the way through to August 26th where it's just not worth paddling out. The winds are mostly onshore or cross-shore, and the combo of that with the swell just isn't coming together. It's a proper flat spell.
Now, there is a little glimmer on August 26th. Wednesday morning things go glassy, dead calm, and we get a bit of life back with a 2ft swell from the west-northwest. The energy's still weak though, only (115). It's surfable, but you'd be scratching for a ride. Don't get your hopes up.
The real standout, the only one worth circling on the calendar, is August 27th. Thursday morning we've got a clean 5ft swell from the west with a moderate 9-second period. The wind is howling from the east-southeast at 19 mph, but it's blowing offshore, which means clean, lined-up faces. The energy's kicking into gear with a reading of (453), so there's some proper push behind it. This is the one to aim for. The water temp is about average for the time of year.
After that, it drops off again quickly into the weekend. A bit of a blank run, but that's how it goes sometimes. Forecasts can flip, so keep an eye on it.
