The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Maenporth.
First up, the water is sitting at 65°, which is a touch warmer than normal for this time of year – nothing crazy, just a nice little bonus.
Right, the honest truth is that this 16-day window is a real struggle. We’ve got a long dry spell of nothing worth paddling out for. The first real look doesn’t come until the end of the month. From now until then, we’re looking at a gap of several days with basically no surf on offer. The conditions are consistently poor, with a lot of wind and messy energy.
The one window that stands out as the best we’ve got is Monday morning, the 31st of August. Maenporth (sheltered spot) will see a 8ft swell from the WSW, with a period of 10 seconds. The combined energy is strong at 1194, so there’s some punch. What makes this the standout is the offshore wind from the WNW at 19 mph, keeping things clean and lined up. It’s a bigger swell, so this is definitely one for the experienced crew. The water temp is still a touch warmer than normal, but that’s just background.
After that, it drops right off again. There’s a marginal-looking window on Thursday morning, the 3rd of September, with 6ft from the WSW and a cross-off breeze, but the energy is moderate (440) and the forecast is questionable. Not a game-changer.
The second week is a write-off. Tiny swells, poor directions, and nothing that’ll get you out of bed. Short-period windswell or long-period leftovers that just don’t have the size.
So, bottom line: if you’re keen, make a play for that Monday morning window. The rest of the run is a good time to clean the wax off your boards.
Rusty.

A general guide to surfing at Maenporth can be found by selecting the local surf guide option on the grey menu.

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.
