Table - best surf conditions forecast for Maenporth over the next 16 days.
Alright folks, Rusty here. Let's have a squiz at the Maenporth forecast. We're looking at a proper dry spell for a while, so patience is going to be the name of the game.
Right now and through the coming week, it's pretty grim. We've got a few pulses of easterly wind and some bigger swell midweek, but that cross-onshore wind is just ruining any chance of a decent wave. From Sunday afternoon the 12th through to the 25th, it's a long stretch of "poor surf conditions" – that's over a week and a half of nothing worth paddling out for. The energy is either weak as, or when it does show up, like on Monday the 13th with an 12ft swell from the east, the wind is a strong cross-onshore at 28 mph, making it a messy, lumpy mess. That kind of size with those winds is only for kites, not a surfboard. The water temp on the 12th is 65°, which is much warmer than normal for this time of year, but that's small comfort when the surf is flat and choppy.
The only real light at the end of the tunnel comes right at the end of the outlook. Sunday the 26th morning shows some life, but it's still marginal with 8ft swell from the southwest. The real standout is Monday the 27th. We've got a solid 10ft groundswell from the west-southwest, with a 10-second period. That's a lot of water moving around, with combined energy of 1825 – a powerful, strong swell. But the real beauty is the wind. Early Monday morning it's glassy, switching to a gentle offshore from the west-northwest in the afternoon. That means clean, groomed faces. At 10ft, this is expert territory, no doubt. For the experienced crew with a big-wave board, that Monday morning session at Maenporth looks like the only real offering in this whole 16-day run. It's a long way off, so don't get too excited just yet, but keep your eye on it.
Rusty.

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.
