The Lowdown
Alright folks, Rusty here. Let’s have a proper look at the surf stretched out ahead of us for Sennen Cove. It’s a bit of a mixed bag to start, but there are some gems hiding in there if you're willing to be patient.
The first few days are going to be a write-off, if I'm being honest. We've got a run of poor conditions kicking off the forecast. Wednesday the 9th is a no-go with a bumpy, cross-onshore mess and not much energy. Thursday isn't any better, and Friday and Saturday are still on the ugly side. You're looking at a solid stretch of poor surf, with the wind just not playing ball at all. You'd be better off doing anything else.
Now, there's a slight change on Sunday the 13th. The swell drops a touch, but the wind goes light and glassy in the afternoon. It’s still only marginal, but at least it's clean. The real window starts to open on Monday the 15th. The wind swings offshore, and the sea cleans right up. It's not huge – around 4ft of west swell – but it's clean and has a bit of push. That Tuesday morning is looking like a proper little session before things get rowdy again.
Hold on to your board, because Wednesday the 16th brings a big pulse of energy. The swell jumps up, but it's accompanied by strong winds and a jumpy surface. That morning might be okay for the brave, but the afternoon sees the swell pushing 12ft and it's going to be a mess. This is expert territory, and even then, it might be more of a drama than a pleasure.
We get a bit of a breather Thursday and Friday, but it's still not great. Then, look at Saturday the 19th. That is the standout. We've got a decent 5ft WNW groundswell, but the real story is the wind. It's swinging offshore and out of the east-southeast, which is going to groom Sennen into some clean, proper waves. It’s not giant, but it’s got good energy, and the offshore wind is going to be a game-changer. That morning is the one to circle on the calendar.
After that, the following week drops off in size and energy. There's some clean surf around Sunday and Monday, but it's small. Then the wind gets strong and offshore, which makes it tough going. You'll be doing more paddling than surfing. There is one last pulse of long-period swell for Wednesday the 23rd, but it brings a strong offshore wind with it. It could be epic, but it's a long way out, so treat it as a promising possibility rather than a certainty. We'll have to see how it develops.
But for now, you can't beat that Saturday the 19th for the best combo of size, clean conditions, and good energy.
Peace out.
Rusty.
