The Lowdown
Alright folks, Rusty here. Let's have a look at what Maenporth has in store for us. Honestly, for the next 16 days, it's a proper waiting game. There's a lot of flat, messy, or just plain ugly conditions in the mix, so don't get your hopes up for a quick fix.
The forecast kicks off with a real thumping but it's unsurfable. Saturday the 29th of August has a solid 10ft to 13ft swell from the southwest and west-southwest, with a combined wave energy of 1194 to 2448. That's strong, powerful stuff, but it's being hammered by a strong breeze at 25 mph. The wind is on it or cross-off, and with that size, Maenporth is just a washing machine. It's a write-off for paddle surfing, and honestly, with that much wind and swell, it looks like the kind of setup that would be more interesting for kite surfing than anything else.
After that mess, things go flat. From Sunday the 30th right through to the end of the first week of September, there's barely a ripple. The combined energy dribbles down to single digits and low double figures. You'll see a few 0.3ft or 0.7ft pulses from the south with periods over 15 seconds, but that's a long-period groundswell with no size to it. It’s a blank stretch of days, and for this area, a quiet spell like that is pretty normal.
The only glimmer of hope in the whole 16-day window is on Friday the 4th of September. The afternoon shows a 6ft groundswell from the west-southwest, with a 9-second period and a combined energy of 519. That's moderate wave energy. What makes it interesting is the wind is offshore from the west-northwest at 12 mph, which should clean it right up. The model says "expect good surf conditions" and gives it a 2/10 score, which is the only positive score of the whole run. For a beginner spot like Maenporth, 6ft is right on the edge of being too big for beginners, so take care. The water temperature is about average for the time of year, nothing unusual to report.
The last hopeful day is Sunday the 13th of September. The morning has a 2ft swell from the west-southwest, but with a very long period of 15 seconds and a combined energy of 384. That's a classic groundswell. It's clean with a moderate breeze, but at 2ft, it's tiny. That long period will make it fat and straight on a beach break like Maenporth, but it's the only other reminder that the ocean is still alive.
So, to sum it up: if you're desperate, the best (and only real) shot is Friday afternoon, the 4th of September. It's promising but not a sure thing. Everything else is a flat, windy, or lully mess. Don't hold your breath.
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.
