Sennen Cove Surf Forecast and Surf Report

Alright, let’s get real about the next couple of weeks. The models are painting a pretty bleak picture for Sennen Cove, if I’m being honest. We’ve got a long stretch of onshores and not much in the way of proper, clean swell. But there are a couple of windows where it might just come together, so don’t write the whole fortnight off just yet.

The first week is a write-off. We kick off Tuesday afternoon with a fresh cross-onshore breeze and a lumpy 4ft of short-period windswell. It’s messy, and there’s no real energy behind it. Wednesday bumps up a bit to 7ft, but it’s still onshore and junky. We’re looking at a lot of chop and not much else. The energy is there, but it's all over the place. That trend continues through Thursday and Friday, with the swell dropping right out. Friday morning is glassy, but the swell is a tiny 1ft – you’d be floating, not surfing. The water is a touch warmer than normal for this time of year, sitting at 66°F, which is notable, but it won’t help the surf.

The weekend and the start of the next week are just as frustrating. Saturday holds some small, clean waves, but at 1ft, it’s barely surfable. Sunday and Monday have a bit more size but the cross-shore winds are ruining any chance of a clean face. There’s a brief moment on Tuesday morning where the wind goes offshore, but it’s howling at 25 mph, making it hard to even get out the back with that 3ft swell. The swell direction is okay, but the wind is just too strong.

Now, here’s where it gets interesting. The first real standout is Thursday, August 14th. The morning looks special. The wind is light, almost glassy, coming from the east-northeast, which is a cross-offshore angle for Sennen Cove. The swell is a clean 3ft from the west-southwest, and the energy is building. It’s not huge, but it’s clean and has some push to it. For a beach break, this is about as good as it gets in this forecast. The combined energy reads 246, which is moderate, but it will feel better than the number suggests with that light wind. This is your window if you want a proper surf.

After that, the swell builds, but the wind swings against us again. The following weekend sees the swell jump to over 7ft, which isn’t a problem in itself, but it’s coming with a cross-onshore wind that will make it a washing machine. By Tuesday, August 18th, we’re looking at 8ft of swell with a strong cross-onshore breeze. That’s big and messy – a day for the experienced, maybe, but not what you’d call quality. The energy is cranking at 1407, showing there’s a lot of power, but it’s all going to be closed out and bumpy. The second week just looks like a lot of lumps and bumps, not much else.

So, to sum it up: if you want a wave, make it happen on the morning of the 14th. That’s your one. The rest is either too small, too messy, or too windy. Keep an eye on the charts, but don’t get your hopes up for anything else in this run.
