The Lowdown
Alright, folks, Rusty here. Let's be straight with you. The next couple of weeks are looking pretty bleak for a proper paddle. We're looking at a long stretch of flatness, so if you're desperate for a wave, you might want to check if the kites are calling your name, because there’s not much else going on.
Looking at the whole picture, we start off with a few small, bumpy swells that aren't worth your time. The energy is weak, with values mostly in the low 100s and even down to single digits (100 to 205). It's going to be a real waiting game. We've got a solid run of days with nothing on offer, so don't hold your breath for the first week.
We finally see a pulse of energy arrive on Thursday the 13th of August. There’s a jump in size to 10ft, but the period is a short 8 seconds, and the energy is strong (960). The wind is cross-offshore, so it might be clean, but that short period is going to make it lumpy and challenging more than anything. That's followed by a 8ft wave on the same day, but the forecast notes it's 'marginal' and the wind is still cross-off, which doesn't inspire a ton of confidence. This is our only real shot at any size, but it looks like a messy one.
After that brief pulse, the swell drops right back off. By Friday the 14th, we're down to 6ft with a short 7-second period, and the energy has dropped significantly (290). After that, it's a total flat spell for the rest of the outlook. There might be some long-period swell lines in the 20-second range (22 seconds on the 15th), but the height is only 0.3ft, so that’s not going to break in any meaningful way.
Aside from that one day of size around the 13th of August, it's a whole lot of nothing. The water temp is a touch warmer than average for Maenporth, but that’s the only thing that’s not disappointing. It looks like a good time to rest up and check back later, because this run is pretty barren.
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.

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.
