The Lowdown
Hey folks, Rusty here. Let's be straight with you – this forecast for Maenporth is a tough one. We're looking at a real dry spell for the next couple of weeks, and I'm not just talking about the weather.
The thing is, this is a sheltered little cove, so it takes a specific kind of swell to get it working, and that just isn't showing up in the charts for a while. To be honest, the first few days are a total write-off. We've got some breeze and, on Thursday the 10th, a bit of swell but with a lumpy cross-shore wind that's just going to make a mess of things. You'd be better off with a kite if that's your thing.
What's frustrating is that we finally get some proper energy and clean, offshore winds on Friday the 11th, with the swell energy hitting 451 – that's a solid, moderate push of west-southwest swell at 5ft. But it's still not enough to really light up this spot. It’s a shadow of a chance. And that’s where the story ends. After that, it all just crumbles.
From the 12th all the way through to the 23rd of September, we're looking at a massive gap with basically nothing on the menu. We're talking tiny, inconsistent pulses of swell with long periods, but there's just no power behind it. It's the wrong direction, dead on arrival. There are a few days with glassy conditions, which would be perfect if there was a wave to ride, but there isn't. It's a real heartbreaker.
So, the honest truth is there are no good surf options in this entire 16-day window. It's a blank run, but that's the nature of this place when the swell direction swings around. Don't lose hope though – these lulls never last forever, and the charts can change quickly. But for now, leave the board in the van and maybe go for a walk. When the water temp is sitting at 64.4°F, which is a touch warmer than usual for this time of year, it just makes it harder to watch it flat.
