The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this is a tough one for the upcoming 16 days at Maenporth. The window is almost completely closed for any decent paddle surfing. We're looking at a long stretch of tiny, flat conditions with hardly any energy pumping in.
The first real pulse of swell we see doesn't arrive until Monday morning, September 7th. The combined energy of all swells directed here jumps to 1,716, which is very strong energy, but it's a messy situation. We've got a 8ft swell from the WSW with a 13-second period. That's a solid groundswell that would normally get the heart racing, but there's a catch. The wind is a cross-off from the WNW at 16 mph, which keeps it clean, but the surf forecast is still marginal. It's a big, powerful swell for a beginner spot, and with a short window of quality, it feels like a tease. The water temp is a touch warmer than normal at 64°F.
If you're determined to get wet, that Monday morning (Sept 7th) is your best bet and the only real standout across the whole forecast. The size is there, but it's really only for the more experienced crew. The south-easterly wind on Sunday (Sept 6th) ruins any chance of that 3ft SE swell being rideable. After that Monday pulse, the window slams shut again. There's a ghost of a chance on Thursday afternoon, September 10th, with a 7ft WSW swell, but it's a short-period 7-second windswell with a combined energy of 404, which is weak energy for a wave that size. It will be fat and crumbly.
The rest of the run is a write-off. We see some strong offshore winds later in the second week, like on Monday the 14th with a 28 mph NW wind, but the swell is tiny and from the east. That's a setup that looks more interesting for kite surfing than paddle surfing. By the time we reach the morning of Saturday, September 19th, we get a 6ft swell from the east, but it's onshore wind and a short period. It's not worth the drive.
Overall, there's a massive gap of poor surf. The only flicker of hope is that Monday morning, Sept 7th. For the rest, you're better off checking the forecast in a few days.
Rusty.

A general guide to surfing at Maenporth can be found by selecting the local surf guide option on the grey menu.

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.
