The Lowdown
Alright, grab your spring suit and listen up. This is Rusty, and I’m looking at Maenporth. It’s a sheltered little spot, and this 16-day run is a real mixed bag. For a beginner-friendly cobble beach, we need the stars to align, and for most of this period, they just won’t. There’s a whole lot of nothing at the start, so don’t even bother waxing up yet.
The first week is mostly a write-off. You’ll see some swell, but the wind is all wrong—cross-on or onshore. Monday the 24th kicks off with a 8ft onshore mess (562 units of energy), and Tuesday the 25th is more of the same but a bit smaller. It stays pretty grim through the 27th. The water temp is 65°F, which is a touch warmer than normal for here.
Our first real glimmer of hope comes on Friday the 28th in the morning. The wind swings light offshore from the WNW, cleaning up the sea. We get a 6ft swell from the WSW, and the energy is moderate at 314 units. The wave comment calls it "surfable but very ordinary," but with a clean face and a little height, a beginner can have some fun on a longboard. Crowds are possible, so you might have to share.
The whole of the first week of September is a washout, but check out Monday the 7th of September. The swell is predicted to go full-on mental. A 13ft swell hits in the morning, but by the afternoon it’s a monstrous 23ft from the WSW with a 17-second period. That’s a very long-period groundswell with massive energy (28,917 units). The wind is a strong offshore from the NNW, so the face will be clean. But here’s the truth: at over 8ft, this is for experts only. Maenporth can’t handle that size—the break will be closing out completely, and paddling out will be a death wish. The forecast confirms it’s too big for this spot, even if the conditions look perfect on paper. Only the madmen and tow crews should even look at it.
Tuesday the 8th settles down a bit, but still holds a solid 10ft swell from the WSW, which is still way too much for the average surfer here.
To be honest, if you’re a normal paddle surfer, the only standout is that Friday 28th morning for a small, clean session. Everything else is either blown out, flat, or way too big. For the big, clean, offshore days around the 7th, this setup looks far more interesting for kite surfing than paddle surfing.
Rusty, signing off.

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.
