The Lowdown
Right then, let’s talk about Sennen Cove.
To be straight with you, this is a tough outlook. For the next week and a half, the wind is all over the place and the surf quality just isn’t there. We’ve got a long stretch of poor conditions from now all the way through to Friday the 22nd of August. There’s some swell in the water, but the wind is mostly cross or onshore, making a mess of it.
The water temperature at the start is sitting at 66°, which is a touch warmer than normal for this time of year, so you won’t need a thick suit, but the wind will make you work for it.
The first real glimmer of hope comes on Saturday the 23rd of August. It’s not a classic, but the wind will swing offshore from the east at a solid 28 mph, cleaning things right up. It’s just that the swell is tiny, only about 1 ft from the SSW, and it’s a long period groundswell of 15 seconds. That kind of long period can make paddling out easier, but at a beach break like Sennen, it might break too straight and be tough to latch onto. The energy is weak (79). It’s more of a paddle-out-and-chat session than a wave-riding session.
The period around Thursday the 28th and Friday the 29th of August is the closest we get to something worthwhile. On Friday the 28th, we get clean conditions with light offshore winds from the east, and a little West swell at about 2 ft to 3 ft. The period is 9 seconds, offering decent shape for a small wave. The energy is weak (46 to 88), but it’s clean. If you’re desperate, that’s your best window for a push-around on a longboard. Sennen is very consistent, so it’s rare to have a blank run like this, but sometimes you have to be patient.
Stick with it, conditions can change. But for now, the setup here is more interesting for the kite crew than the paddle crew.
