The Lowdown
Alright, Rusty here, checking in on the local surf scene for Maenporth. Grab a coffee, because we’ve got a long-range look ahead.
Right, straight up, this isn't a week for grabbing your board every day. We’ve got a big patch of flat, poor conditions stretching from now, Sunday the 6th, right through until the end of the week. It’s a real quiet spell. The water temp is sitting around 64°, which feels a touch warmer than normal for this time of year, but there’s just no energy in the water to go with it.
The one true standout, and honestly the only real window of opportunity, hits us on Monday the 7th. Maenporth wakes up to a solid pulse of groundswell. We’re looking at a clean 7 ft swell coming out of the WSW, with a long 13-second period pushing a hefty amount of energy (1433). The wind is offshore from the WNW, which will keep the face nice and clean. That’s the session to circle. Monday afternoon still holds decent 7 ft swell with clean conditions, but it’s not quite as good as the morning. This is a proper swell, over 5 ft, so it might be a bit much for the groms and beginners.
After that Monday blast, it all drops away again. Tuesday the 8th shows a tiny bump but nothing rideable. We get another look on Friday the 11th with a 5 ft swell and light offshore winds, making for some clean, surfable waves, but it’s ordinary – not a standout.
The rest of the forecast is a long, dry run of tiny waves and onshore or cross-shore winds right through until the end of the second week. There’s a late flash on Monday the 21st of September, over a week and a half away, showing a big 8 ft to 12 ft pulse of swell, but that’s a long way off and the conditions are listed as marginal, so it’s one to keep an eye on, but don’t bet the house on it yet. For now, the best on offer is that Monday morning session.
Rusty.

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.
