The Lowdown
Alright, let’s get into it. I’ll be straight with you: this looks like a tough stretch for Maenporth. For a sheltered little cove that needs a specific south-southeast angle to work, we just aren’t getting the right push for basically the whole 16-day window.
We open up on Thursday the 10th with nothing – a flat, lumpy, cross-shore mess. Friday the 11th morning is actually the best we’ll see across the whole period. A 5 ft WSW swell rolls in with a clean 9-second period and solid moderate energy (400) under light offshore NNW winds. That’s clean, it’s rideable for a beginner-friendly wave, but the break is inconsistent at the best of times, so don’t expect a constant line-up. That Friday morning window is the only real standout – it’s the best on offer. After that, Friday afternoon drops to 4 ft with cross-off wind, still clean but losing energy fast.
From Saturday the 12th onward, it’s grim. We’ve got tiny, high-period leftovers – periods of 13 to 18 seconds on swells under 0.3 ft – that just don’t have any push. The combined energy drops to single digits most days. There’s a long stretch from Saturday the 12th right through to Wednesday the 24th where there’s nothing worth paddling out for. A few mornings have offshore winds, but when the swell is a whisper and the wave comment says “poor surf conditions,” you’re not missing much.
Even right at the end, Friday the 25th, it’s flat with fresh offshore wind – clean but no surf.
Honestly, if you’re hanging for a wave, that Friday 11th morning is your one chance. A small, clean, beginner-friendly window. After that, put the board away for a while. For an area like this, a blank run is normal when the angles don’t line up. Forecasts can change, but right now, it’s a waiting game.

A general guide to surfing at Maenporth can be found by selecting the local surf guide option on the grey menu.

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.
