The Lowdown
G’day, Rusty here. Look, I’ve scanned the charts for the next sixteen days, and I’ll be straight with you – it’s a proper wipeout for Maenporth. There’s nothing worth paddling out for right through to the end of the forecast. The whole run is basically a flat spell with a few tiny, weak bumps that won’t get you wet. The first glimmer of anything resembling a wave doesn't show up until Thursday the 27th of August, which is a week and a half away, and even that’s no good. So, brace yourself for a long, quiet gap of nearly two weeks with nothing to offer.
Let’s walk through it. This Thursday morning, the 13th, we’ve got a small 4 ft swell from the WSW with a period of 11 seconds – the combined energy is weak at 299 – but the wave comment already says it’s poor, and I can see why. The water temp is a touch warmer than normal at 66°F with a 4°F anomaly, so a bit of a warm patch, but that’s no consolation with no surf. That afternoon and all through the next few days, the swell drops to nothing – 1 ft, 0.3 ft – with useless wind directions and no energy. Friday the 14th, Saturday the 15th, Sunday the 16th… it’s all dead. We get some offshore winds on occasion, but with no swell, it’s just a glassy pond.
It stays like that right through the following week. The 19th and 20th see a tiny 0.7 ft SSW pulse with periods of 16 seconds and combined energy only in the low teens to twenties – that’s next to nothing. Winds are mostly offshore or clean, but you can’t surf zero. Even on the 22nd of August, we get a 0.7 ft SSW swell with a 15-second period and energy only at 39 – still pathetic.
The only real change comes on Thursday the 27th of August. The swell finally kicks up a bit – 4 ft from the SSW at a short, windy 5-second period – energy reads 66, so still weak. The catch? The wind is howling from the NE at 19 mph, straight cross-shore, lumpy and messy. It’s too choppy for a decent paddle. That same day afternoon, it drops to 3 ft, still cross-shore and rough. And then it’s back to tiny nothing for the rest of the month. The 28th of August has 0.3 ft – forget it.
Honestly, there’s no standout here. Not a single session worth chasing. The spot is sheltered, inconsistent, and it’s just not working for us this time. If you’re dying for a paddle, maybe the one morning of the 14th with light WNW winds and a tiny 0.3 ft S swell – but that’s a stretch. For now, leave the board at home. Forecasts can change, but this blank run is more normal for the area when conditions line up like this.
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.
