The Lowdown
Alright folks, Rusty here. Let’s have a look at what Maenporth’s got cookin’ for the next couple of weeks. Gotta be straight with you – for a place that’s a little sheltered and inconsistent as it is, this is a tough one. We’ve got a long dry spell to start.
The opening here is grim. From Monday the 31st of August all the way through to the morning of Monday the 7th of September, there’s nothing worth paddling out for. That’s over a week of flat or messy conditions. The swell that shows up early on the 31st is a whopping 10 ft from the WSW, and while the wind is offshore and clean, the wave comment flags it as marginal, and the whole setup just isn’t coming together for a decent ride.
The first real flicker of hope arrives on the afternoon of Monday the 7th of September. The wind goes offshore from the NNW and we get some moderate energy pushing in – about 5 ft of swell from the WSW with an 11-second period. That’s a solid groundswell, and the combined energy reading of 618 (moderate) tells you there’s some proper push behind it. The break here is Maenporth, and it’s a sheltered spot that likes a SSE direction for its optimum, so this WSW swell isn’t a perfect match, but with clean conditions and that size, it could offer up a few decent ones. Crowds can be an issue here though, so expect company if you go.
Looking further out, we get another pulse around the morning of Wednesday the 9th of September – 6 ft from the south, but it’s a short period of 6 seconds and a fresh cross-offshore wind. That’s a bit of a messy combo, and the energy is only moderate. Definitely not the standout.
The one that’s got my attention is later in the window, on the morning of Thursday the 10th of September. We’re looking at 8 ft of swell from the WSW, with an 8-second period. That’s a fat, powerful wave, and the combined energy is pumping at 1352 (strong). The wind is offshore from the WNW, so it’ll be clean. Now, 8 ft is getting solid – this is expert territory. For the average weekend warrior, this is going to be a handful, especially at a break that can be inconsistent. But for the crew who know what they’re doing, this could be the best session of the outlook. It’s over a week away, so treat it as a promising possibility rather than a sure thing.
After that, it’s flat again. We get another big spike on Monday the 14th of September with 10 ft from the WSW and 9-second period, but the wind is cross-shore and the conditions are flagged as marginal. That’s more of a challenge than a treat.
So, if I’m picking one or two standouts: the afternoon of the 7th of September is your best bet for a manageable, clean surf. But if you’ve got the skill and the patience, keep an eye on the morning of the 10th of September for a proper, powerful session.
Rusty.

Information about the Maenporth Surf forecast
The above surf forecast table for Maenporth provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
