The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s cookin’ for Maenporth. It’s a bit of a quiet start, a real waiting game, but there are a couple of flashes of life if you’re willing to be patient.
The water’s sitting at a warm 64°, which is a touch warmer than normal for this time of year. Feels like a late summer blanket.
Right, the first few days are grim. From the 1st of September right through the 6th, it’s a desert. We’re talking tiny, weak swell with barely any energy. The combined energy values are all well under 100 (12, 69, 21, 18 – you get the picture). The wind is a mess, mostly cross or onshore, and the swell is short-period and weak. Not worth paddling out for. Saturday the 5th has a glassy morning, but the swell is only 0.7ft from the SSW. That’s a flat spell, plain and simple.
Then we get a flicker. Monday the 7th of September. This is your standout window. The morning brings a solid 7ft swell from the WSW with a 13-second period. That’s proper groundswell energy. The combined energy is a whopping 1401, which is strong. The wind is a light, 6 mph Westerly, so it’s a clean cross-offshore breeze. This is the best wave of the entire forecast. The afternoon holds up at 7ft from the WSW, though the energy drops a bit to 1163 and the wind picks up to 12 mph. Still clean, but the morning is the pick.
Remember, at 7ft, this is getting into the territory where it’s too big for beginners, and the longer period (13 seconds) means it’ll be a proper, powerful wave. It’s an inconsistent spot normally, so a window like this is a real treat. The crowd factor is "often" here, so expect company for the good stuff.
After that high, it all goes quiet again. The 8th and 9th of September are a total write-off with tiny, weak swell and strong winds, including a 28 mph WNW on the Wednesday morning. We then have a long stretch of poor surf. The 10th has a small 5ft pulse in the afternoon, but it’s short-period and not enough to get excited about. The 11th, 12th, and 13th are all poor, with strong onshore winds and messy conditions.
Thursday the 15th of September offers one more potential. The morning shows a 6ft swell from the WSW with a 9-second period and a combined energy of 671. The wind is a gentle 9 mph Westerly, staying clean. The afternoon is similar but with a 10-second period and a slightly lower energy reading of 583. It’s a promising call, but it’s over a week away, so treat it with a pinch of salt. Could be a good session, but it’s not as locked in as the 7th.
The 16th of September goes flat again.
So, to sum it up: the first week is a dud. The absolute standout is Monday the 7th of September, morning session at Maenporth. That’s your best bet. The 15th of September is a long-range backup that might come good. Get on it when you can.
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.
