The Lowdown
Alright, this is Rusty. Gonna break it down for you – Maenporth over the next 16 days is a real mixed bag, and to be honest, it's a tough one for paddle surfing.
We kick off with small, weak, messy conditions. From Thursday 27th August through the weekend, southerly and westerly winds are blowing cross or cross-off, with the swell size all over the shop. There’s a big spike on Saturday 29th August – waves hitting 8ft to 12ft – but the wind is a problem. It’s a near gale or strong breeze, making for a choppy, lumpy mess. The combined swell energy is moderate to strong, but with those winds, it’s a no-go for a good ride.
Then we hit Monday 31st August morning, and this is where it gets interesting. The wind swings offshore from the WNW at 15 mph, and we’ve got a clean 8ft swell from the WSW with a period of 10 seconds. That’s the standout window. The combined energy is strong, and the conditions are set for some proper, clean waves. This is the one to circle on the calendar – but keep an eye on the tide, as the file suggests it might be a bit of a puzzle. This break is sheltered here, so it’s handling that WSW groundswell nicely.
The rest of the first week is pretty quiet, with tiny waves and clean but powerless conditions. The water temp is 65°, feeling a touch warmer than normal for this time of year.
Moving into the second week, things get bleak. From Tuesday 1st September right through to Saturday 5th September morning, there’s a long gap of almost nothing – we’re talking less than 1ft swells. It’s clean but tiny. On Saturday 5th September morning, we get a little pulse: 7ft from the WSW at 8 seconds (moderate energy), but it’s cross-shore with a light wind ripple on the surface. It’s marginal, and honestly, not worth rushing out for. After that, it’s more tiny, clean slop right to the end of the forecast.
So, if you’re a beginner, most of this is either too small or too windy. The bigger days (over 8ft) are for experts only with those strong winds. The only real standout is Monday 31st August morning – clean, solid, and offshore. That’s your moment. The rest, you’re better off doing something else.
Rusty.

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.

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.
