Hey, Rusty here. Let's break down what’s happening at Mawgan Porth.
It’s a lean patch ahead. The water’s running about 63°F, which is a couple of degrees warmer than usual for this time of year – a bit of a treat, but that’s where the good news starts and mostly ends.
The first few days – through Saturday, Sunday, Monday, and Tuesday – are a write-off. Small, weak swell with onshore wind. The energy is low, and it’s just messy out there. Don't bother.
Wednesday the 8th and Thursday the 9th show a little life. The swell is only about 2ft from the west, period around 9 seconds, but the wind turns cross-offshore from the NE and N. It’s clean, but the energy is still weak. You’ll get a few, but they won’t be memorable.
Friday the 10th is more of the same – 3ft west swell, cross-offshore wind. Clean but weak.
Here’s the one window that matters. On Saturday the 11th of July, the afternoon goes glassy calm. The swell pushes up to 5ft from the north, with a short 6-second period. Energy is moderate. That flat wind will make the river mouth look like a different spot – clean, fun little wedges. That’s your best session by a mile. Just a heads up, 5ft can be a bit much for beginners.
Sunday the 12th is okay with a 4ft north swell and a 20 km/h offshore breeze from the east, keeping it clean. Not as much power as Saturday though.
Then it’s a long dry spell. From Monday the 13th all the way through to the 19th of July, the swell disappears. Tiny waves, poor wind, and no energy. Even the 3ft on the 19th is blown out by onshore wind.
So the takeaway: Your one shot is that glassy Saturday afternoon on the 11th. The rest is a quiet stretch, which is fairly normal for this spot. Keep the board waxed and wait.
Rusty.
