The Lowdown
Alright folks, Rusty here, and I’ve got a look at Maenporth for you. I gotta be straight with you – this 16-day outlook is a tough one. We’re looking at a long stretch of very quiet conditions, and for a spot that’s already classed as inconsistent, a run of poor surf for the better part of a fortnight is a real bummer. The first recommendation doesn't pop up until the 11th, but even that is a washout. Let's walk through it.
Tuesday the 8th kicks off with a bit of energy – about 4ft from the WSW (255 combined energy), but that's paired with a fresh 19 mph NNW offshore wind, so the surf shape is just poor. The water's running at 64°F, which is a touch warmer than usual for the time of year, so that’s something. Still, it’s a no-go. The rest of the week stays small and messy.
Then we hit a proper lull. From Wednesday afternoon the 9th right through until Sunday the 14th, we’re talking about barely a ripple, with swell heights of 0.3ft and combined energy readings just 3 to 9. The wind might be clean, but there's nothing to surf. That’s a solid four-day gap with nothing on offer.
The next blip comes on Friday the 11th morning, with 5ft of WSW swell (391 combined energy). That's the most energy we see in the whole period. It’s a moderate 12 mph NNW cross-offshore wind, keeping things clean, but the guidance still scores it as poor surf conditions because the quality isn’t there. The rest of Friday and into the weekend just falls flat again.
From the 12th through the 22nd, it’s a rinse and repeat of tiny, weak swell – mostly 0.3ft or less – and on-shore slop from the east. The energy stays in the single digits for days on end. It’s not surfable. There's a flicker on the 23rd of September – Wednesday morning and afternoon – with 4ft to 4ft from the east, but that’s a short period, 5 seconds, and a brutal 25 mph cross-onshore wind producing messy conditions. For a sheltered break like Maenporth, that’s not doing anyone any favours. It looks more interesting for kite surfing than paddle surfing that day.
So, the bottom line: there are zero standouts here. The only time there’s any real swell size is when the wind is just wrong, and the rest is a flat spell. For beginners, nothing gets over 5ft that’s rideable, so that’s small comfort. It’s a dry run. Forecasts can change, but for now, you’re better off doing something else.
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.
