The Lowdown
Alright crew, Rusty here. Let’s break down Mawgan Porth. I’ll be honest – this stretch of days looks pretty bleak. There’s a long, grim gap of surf that’s just not worth your time.
Right from the start, Friday the 7th through Monday the 11th, it’s tiny. We’re looking at 0.6 to 1 feet of weak, short-period slop, with combined swell energy barely hitting 34. The wind is all over the show, mostly cross or onshore, so it’s a total write-off. Don’t even bother.
Tuesday the 12th of August offers a little hope, but it’s a tease. The Wednesday morning session sees a bump to 3 feet from the west, with a 10-second period. The combined swell energy jumps to a moderate 155, and the wind goes glassy. That’s the cleanest it’ll be, but the waves are still just “surfable but very ordinary.” It’s a beginner-friendly wave on a river mouth, but it’s not going to get you stoked.
After that, it’s back to the doldrums. Thursday the 13th has a 2-foot swell with a 11-second period, but the cross-on wind spoils it. The energy is moderate at 211, but the quality is poor. The rest of the second week gets bigger but stays ugly. By Sunday the 16th, the swell pushes to 5 feet, then 6 feet, with energy climbing to 364, but it’s all onshore wind and choppy mess. For a beginner spot like this, that’s no fun.
The real kicker comes on Friday the 21st of August: a 10-foot swell from the WSW, hammered by a strong cross-on breeze of 25 mph. The combined swell energy is a hefty 903, but it’s a washing machine. That’s kite surfing territory, not paddle surfing. The river mouth will be a blown-out mess.
Water temp is about average for this time of year, so no surprises there.
If you’re keen for a paddle, that Wednesday morning on the 12th is your only real option. It’s clean, small, and safe for beginners. But there’s no standout surf in this 16-day window. The whole run is a bust. Forecasts can change, but for now, I’d leave the boards in the shed.
Rusty.
