The Lowdown
Alright, Rusty here. Let’s look at Maenporth.
Honestly, mate, if you’re hoping for a proper surf session over the next 16 days, you’re going to be let down. It starts out poor and never really gets going. The whole window is a bust for any decent waves.
Starting Wednesday the 12th, it’s poor. The water is running a touch warmer than usual for this time of year, but that’s the only upside. You’ve got a tiny 3ft swell from the WSW, but it’s cross-on and choppy with a moderate breeze out of the ESE at 15 mph. Not worth getting wet.
Thursday the 13th morning looks cleaner, with offshore wind from the NNW at 9 mph. The swell picks up to 4ft from the WSW with an 11-second period. The combined energy is moderate. But it’s still rated as poor – likely just too weak or inconsistent for this sheltered spot. The afternoon drops right off to just 1ft.
From there, it’s a long flat run. Friday the 14th is barely a ripple at 0.3ft. Saturday the 15th, Sunday the 16th, Monday the 17th – all tiny, with the swell barely showing. The winds are mostly clean, cross-off or offshore, but there’s simply no wave energy. The combined energy numbers are all below 30, which is weak.
This flat spell carries on right through until Wednesday the 20th. There’s a couple of afternoons with gentle offshore breezes, but the swell is still only 0.7ft. By Thursday the 21st, the wind swings onshore and it gets messy.
A tiny blip shows up on Saturday the 22nd of August. We get 3ft to 4ft of swell from the east, with a very short 5 to 6-second period. The combined energy hits moderate levels in the afternoon. The wind is cross-off from the WNW at 18 to 22 mph. It’s clean, but the short period means it’ll be weak and junky. Still, it’s the biggest swell in the entire 16 days. The break is inconsistent and sheltered, so don’t expect much. The wind is fairly fresh, so conditions won’t be glassy.
After that, it’s back to tiny, clean but useless waves for the rest of the run. The forecast confidence for the 22nd is as good as it gets that far out, but even that is not a standout.
There’s nothing worth chasing here. Maenporth is a sheltered break, and the swells just aren’t reaching it with any power. This area seems to have long flat spells like this. Keep an eye on it, but don’t get your hopes up.
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.
