The Lowdown
Alright folks, Rusty here. Let’s get straight into it. To be brutally honest, the next sixteen days at Mawgan Porth are a tough watch. The forecast basically has nothing worth paddling out for, with the first proper sniff of anything rideable not showing up until the 16th of September. That’s a long, dry spell.
The water is sitting at 64°, which is a touch warmer than normal for this time of year, so at least it’ll be comfortable while you’re sitting there waiting for a wave that never comes.
There’s a real tease on Monday the 7th of September – a solid 7ft swell from the west with a long 13-second period, and the combined energy is pumping. But the wind is onshore and howling, trashing it completely. That’s a write-off for a paddle board. If you’re a kite surfer, that’s a different story, but for us, it’s a no-go.
The only glimmer of hope arrives on Wednesday the 16th of September. First thing in the morning, we’ve got a clean, cross-off breeze from the NNE at 6 mph, with a 3ft west-northwest swell. The period is a solid 11 seconds, giving it some shape. The combined energy is weak, so it’s small, but the wind is clean. It’s surfable, but only just, and it’s very ordinary. That’s the one and only standout in the whole window, and that’s a pretty sad highlight.
Everything else is a mix of onshore slop, cross-shore chop, or just flat. If you’re a beginner, don’t even bother – the one clean day is too small for learning, and the bigger days are way too messy. This is a rough stretch. The river mouth might offer a tiny bit of shelter, but the forecasts don’t support it.
Rusty.
