The Lowdown
Alright folks, Rusty here. Let's be straight with you—this is a tough one. We're looking at the next 16 days for Maenporth, and to be honest, the surf forecast is looking pretty bleak. There's a big fat gap right from the start, so don't even bother waxing up for a while. The first time we even see a hint of a wave is on the afternoon of Friday, September 11th.
Let's get the water temp out of the way first. At 65°F it's a touch warmer than normal for this time of year, which is a nice little bonus if you're just floating around.
For the first week, from Thursday, September 10th right through to Thursday, September 24th, the story is mostly about tiny, weak, and inconsistent swell. You'll see a few spikes of energy, but the combined wave energy barely cracks 100—it's all weak stuff. The only real mention of a rideable wave comes on Friday afternoon, September 11th. We've got a clean 4ft swell from the WSW, with a 9-second period, and the wind is blowing offshore from the WNW at 9 mph. That's a glassy, clean setup. But it's a Maenporth, which is a sheltered spot that's inconsistent and often crowded. Even with that clean window, the wave energy is still weak, and the "poor surf conditions" label tells you it's not going to be anything special. The offshore wind is a major positive, but the tiny swell and inconsistency make it a real gamble.
After that, it's a long, dry spell. From Saturday the 12th all the way through to Thursday the 24th, we're looking at knee-high dribble with periods that are all over the place. The wind is often offshore or cross-offshore, which is great for clean conditions, but there's just no energy behind it. The combined energy stays in the single digits or low teens for most of that run. It's a total standstill.
Then, on Friday, September 18th, the afternoon kicks up a bit. We see a 4ft swell from the WSW, with a short 6-second period and a combined energy of 119 (moderate). The problem is the wind is a fresh cross-shore from the SW at 19 mph, making it lumpy and choppy. It's a mess. The swell is there, but the quality is poor. For a break like Maenporth, that's a kite-surfing day, not a paddling day.
The best bet—and I'm being generous here—is still that little window on Friday afternoon, September 11th. The offshore wind and clean conditions are a standout, but you're relying on a tiny, inconsistent swell. For the rest of the 16 days, it's a tough slog. The consistent offshore winds do mean the water will be clean, but with no wave energy, it's not going to get your heart racing. Hang tight, check the forecast again in a few days—things can change, but this one looks like a proper flat spell.
Rusty.

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.
