The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks.
Honestly, it’s a bit of a tough stretch for Maenporth. The wave energy is weak for the first week, and those clean, rideable windows are few and far between. We’ve got a long gap with nothing worth paddling out for from the start. From the 1st of September right through to the morning of the 8th, it’s all poor surf conditions. A few tiny scraps of swell with that 0.3ft to 0.7ft range and some decent wind here and there, but nothing with enough push to bother.
On the morning of the 8th, things perk up a little. We get a pulse of 5ft swell from the WSW, period around 9 seconds, and the combined energy jumps to a moderate 376. The wind is light and cross-offshore, which should keep it clean. It’s surfable, but the conditions are still very ordinary. Not a standout, just a glimmer of hope in a quiet run.
The real highlight, the only one worth marking on the calendar, comes on the afternoon of the 15th. We’ve got 3ft swell from the WSW with a 12-second period, giving it some proper groundswell shape. The combined energy is a solid 499, so there’s a good amount of power for a wave that size. The wind is light and variable, nearly glassy, with that cross-offshore angle. This is the cleanest and best setup of the whole outlook. The crowd factor, though – this spot is often busy, so expect company if you head out.
Right now, Maenporth is a sheltered spot, and with the swell direction coming from the SSW optimum, it needs the right angle to fire. The water temp is about average for this time of year, nothing unusual.
For the second week, that’s your one shot. The morning of the 16th sees another 7ft bump, but it’s from the E with a short 7-second period and a nasty cross-onshore wind. That’s a mess. So pin your hopes on that Tuesday afternoon. Promising, but way out there, so keep an eye on the charts.

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.
