The Lowdown
Alright, Rusty here. Let me level with you. Right now, theres and will stay a moderate gap of no surf that you want to see.
From Thursday the 13th of August through to Tuesday the 25th of August, theres just no decent waves for Maenporth. Its basically a nine-day flat spell. Swell is basically non-existent, rarely climbing over 1 foot, and what little shows up is junk — short period, weak energy, and mostly cross-off or cross-on wind. No point even looking at the board for that stretch.
Now, on Wednesday the 26th of August, weve got a that sudden little bump in energy, but the winds are messy with a "risk tstorm" and the period is a short 7 seconds. Not worth paddling out for.
But heres where it gets interesting, on Thursday the 27th of August. Weve got a proper, notable surge. It hits Thursday morning with 5 feet from SSW, period at a very poor 7 seconds, but combined energy of 231. Its still in the "poor surf conditions" file, but look: the break is sheltered and the wind is cross-offshore (fresh breeze, 18 mph), so itll be clean. By Thursday afternoon, the swell bumps to 7 feet from WSW, period only climbs to 8 seconds, but combined energy jumps to 531. Thats moderate wave energy (531). This is only for experts though — 7 feet is solid, maybe even heavy on a small wave day. The cross-off wind means the face will stay clean, but at this size, its gnarly.
For the end of the stretch on Friday the 28th, morning drops back to 3 feet from SSW, 6-second period, but the energy is 146 and the wind is still cross-off. Surfable for maybe a quick session if youre keen on a short period windswell.
So, stand out here? There really isnt a "standout" in the true sense. The one redeeming moment is Thursday the 27th afternoon when the swell pushes 7 feet and it feels like the ocean finally woke up. Its big, its raw, and its for the experienced crew only. Maenporth is usually a sheltered spot, so getting that kind of size with clean cross-off wind is a rare treat. Dont expect crowds to be an issue because its inconsistent normally, but on that Thursday, if there are any locals around, theyll be on it.
As for water temp, I dont have a number in the file, so no call on that. But trust me, by late August around here, its usually fine without a winter suit.
Rusty, signing off.

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.
