The Lowdown
Alright, let’s cut to it for Maenporth.
The only real window you’ve got is Monday morning, September 7th. We’re looking at a 7ft WSW swell with a 13-second period—that’s proper groundswell energy, reading 1433 on the combined scale. Wind is offshore out of the WNW, and the call is "very good surf conditions." For a sheltered little cove like this, that’s your best shot. Water temp is 65°F, running about 3°F warmer than average for this time of year. That’s a nice little bonus.
After that, it’s a long, long flat spell. Monday afternoon is still 7ft but not as clean, and then from Tuesday the 8th right through the middle of the month, it’s basically nothing. Tiny waves, short periods, cross-shore slop, and a lot of waiting around. There’s a slight bump on Friday the 11th with about 4ft, but the energy’s weak and it’s not worth the paddle.
You’re looking at a solid week to ten days of nothing from the 8th onwards. The second week is even worse—ankle-biters, onshore breezes, and no swell generating in the forecast at all. The combined energy numbers drop to single digits, which is as dead as it gets around here.
So here’s the story: if you can get out Monday morning, do it. That’s the one. The rest of this 16-day outlook is a drought. It’s just one of those quiet stretches for the area, but hey, things can change. As it stands though, don’t hold your breath.
Rusty signing off.

Information about the Maenporth Surf forecast
The above surf forecast table for Maenporth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Maenporth can be found by selecting the local surf guide option on the grey menu. Our Maenporth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Maenporth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
