The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Maenporth. Gotta be straight with you – this stretch is looking pretty flat and quiet. We’ve got a long gap of nothing happening before we finally see a pulse of energy, but it’s a blink-and-you’ll-miss-it affair.
The opening days are a write-off. Thursday the 3rd has some swell pushing 6 ft from the WSW, but with a short period of 8 seconds and a moderate cross-off breeze, it’s just messy. The water’s a touch warmer than normal at 64°, about 3° above average, but it doesn’t help the waves. This is a no-go.
Then we hit a big dead zone. From Friday the 4th right through to Wednesday the 9th, it’s flat – practically nothing. The swell barely registers, with combined energy readings as low as 2 to 20. There’s a glassy morning on Saturday the 5th, but the swell is only 0.7 ft, so you’re just looking at a mirror. That’s a solid 6-day stretch with no real surf.
The first and only real glimmer comes on Thursday the 10th. The afternoon brings a 7 ft swell from the WSW, a period of 8 seconds, and the wind goes glassy. The combined energy hits 474 – that’s moderate wave energy. It’s a decent-sized, clean little window. But Maenporth is a sheltered spot, so that 7 ft WSW groundswell might not pour in with full force. It’s also inconsistent here, so you’ll have to be patient. Still, if you’re a beginner, that 7 ft is getting a bit big for comfort.
After that, from Friday the 11th onward, it’s back to the doldrums. Swell drops to 5 ft and then fades to nothing. The rest of the second week is a mix of tiny windswell, onshore junk, and flat spells. The best you’ll see is 3 ft from the east on the 18th, but with onshore wind and a weak 5-second period, it’s not worth the paddle.
So, the standout? It’s Thursday the 10th of September, hands down. That glassy afternoon with 7 ft WSW is the one moment where it might be worth a look. For the rest of the 16 days, you’re better off waxing your board and waiting for the next system.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Maenporth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
