The Lowdown
Alright folks, Rusty here. Let's be straight with you about what’s on offer for Maenporth over the next couple of weeks. I've got to be honest, it’s a bleak picture. The first proper surf window just isn't there, and the whole 16-day stretch is looking like a write-off for paddle surfing, so we’re in for a long, flat run. The water is sitting at about 64°F, which is a touch warmer than normal for this time of year, but that won't help you get a wave.
We start on Friday the 11th with nothing – zero energy (0). The wind is offshore and clean, but there's no swell to work with. That theme carries on right through the next week. Saturday the 12th sees a tiny 0.3 ft south swell creep in, but it’s long-period (15 seconds) and the wind is cross-shore, making for poor conditions. The combined energy is barely a whisper (7). This same story repeats day after day through the 13th, 14th, 15th, and 16th: tiny bits of swell, often with cross or offshore winds, but nothing with any push or shape. The combined energy values are all below 10, which is just dead. There’s a period around the 16th and 17th where the swell just disappears again entirely (0).
Moving into the second week, we finally see a slight pulse on Sunday the 21st, but it’s a weak 2 ft from the ESE with a terrible 4-second period. The wind is cross-onshore and choppy, the energy is only moderate (23). That’s a total mess – more of a wind-slap than a wave.
The only slight blip of interest comes on Thursday the 24th of September. The afternoon shows a 1 ft west-southwest swell with a long period of 18 seconds. The combined energy finally hits triple digits (111), which is the only moderate energy we see. The wind is a fresh cross-offshore, keeping things clean. But honestly, 1 ft with that long period is going to be weak and fat on a sheltered beach break like Maenporth. This set-up looks far more interesting for a kite surfer than for anyone on a paddle board, especially with the strong wind that follows.
There is nothing here for the beginner or the expert. The swell never gets anywhere near 5 ft, so crowds aren't a factor because nobody is going to be out. This is a genuine blank run, and for this area, that’s just the way it goes sometimes. Forecasts can change, but right now, I’d find something else to do for the next fortnight.
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.
