The Lowdown
Alright, crew, Rusty here. Let’s be straight: the next couple of weeks are looking pretty grim if you’re after quality waves. We’ve got a long, flat spell ahead, so don’t be in a rush to wax up just yet. The water’s sitting at a touch warmer than normal for this time of year, about 64.2°F, so that’s one small silver lining.
The first bit of real hope shows up a few days out, on Monday, September 7th. We’re looking at a bump of southwest swell pushing in, around 7.2ft with a 13-second period from the WSW. The energy jumps right up there too, with a combined reading of 1571, so there’s some proper juice behind it. Maenporth (Falmouth) will be the spot to check, but I gotta warn you, it’s a sheltered, inconsistent sort of wave even on a good day. The wind is coming cross-offshore from the west, which could keep it clean, but the call is "marginal." It’s not going to be a classic, but it might be the only show in town. Monday afternoon backs off a touch to 6.9ft, so the morning looks like the better bet there.
After that little pulse, it fades fast. Tuesday the 8th has a tiny 0.3ft wave in the morning, and while the afternoon bumps up to 3.9ft, it’s still pretty weak. The following days are just flat out poor. There’s a bit of a swell on Thursday the 10th, with 7.5ft on the afternoon, but the period drops to 8 seconds which makes it junky and the energy reading, at 704, is way down from Monday. It’s not going to be worth the paddle. After that, the ocean just goes to sleep. We’re looking at a string of days with nothing but dribbles and close to zero energy, all the way through to the 17th.
Honestly, for the next two weeks, Monday the 7th is your only real shout, and even then, it’s a "maybe." If you're desperate for a paddle, that's your window. Otherwise, I’d be doing something else. With this much west wind and weak, choppy swell, Maenporth is going to be more interesting for the kite crew than us surfers. Keep the board in the car, but don't hold your breath.

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.
