The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what Maenporth has lined up for the next couple of weeks. I gotta be straight with you – it’s a lean run. Real lean.
We’ve got a long quiet spell kickin’ off with barely a ripple. For the first week, it’s mostly tiny, wind-affected dribble or flat spells. The water temperature is sitting around 64°, which is a touch warmer than you’d expect for the start of September. Nice for a paddle but not much else. There’s a big gap here with no worthwhile waves at all until we get into the second week.
Monday the 7th of September afternoon is the first time something shows a pulse. The combined energy jumps to 1256, which is a strong punch of juice, driven by a 7.2ft swell from the WSW with a 12-second period – that’s proper groundswell. The wind is WNW, blowing cross-offshore. That combo could set up some clean, punchy lines. It’s a short-lived spike, and so late in the day, it’s more of a promising sign than a guaranteed session.
Other than that one moment, the entire 16-day window is a write-off for a paddle. The combined swell energy stays low, rarely cracking three-digit values, and most scans are showing poor surf conditions. For a sheltered little nook like Maenporth, it’s not too unusual to see a blank run of this length when there’s no big Atlantic juice lined up right. The forecast can always change though, and this stretch of coast normally picks up the scraps, so keep your eyes peeled.
Forget the board for the first week. Honestly, that Monday the 7th afternoon is your one and only standout – a sudden, punchy groundswell with solid 7.2ft heights and clean cross-off wind. It’s expert territory at that size, and the long period (12 seconds) will make it a bit straight for a beach break. But for one afternoon, it’s the only game in town.
That’s all I’ve got for Maenporth this time. Keep looking at the horizon.

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.
