The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the forecast for Maenporth over the next 16 days is a proper flat spell. We’re looking at a long stretch of no good surf on offer, so don't get your hopes up for any kind of session.
We start on Wednesday, July 15th, with a bit of swell showing, but it’s a write-off. The wind is howling from the east at 19 mph, making it a lumpy, cross-onshore mess. The wave energy is weak (162), and the water is sitting at 65°, which is much warmer than normal for this time of year. That’s about the only noteworthy thing. The rest of the week is a dead loss. Thursday, July 16th, the swell drops right off, and the wind stays cross-shore. Friday, July 17th, we get a few tiny clean waves in the afternoon with a light offshore breeze, but the swell is only 2 ft and the energy is negligible (34). It’s not worth paddling out for.
The weekend and all of the following week are just as bad. The swell is flat to tiny, and even though we get some glassy or clean conditions on Monday, July 20th morning, with the wind going glass, the swell is a pathetic 1 ft with an energy of just 3. That’s a lake, not a surf break. The pattern of poor conditions just keeps repeating. There’s a few days where the wind goes clean offshore, like Thursday, July 23rd, but the swell is still only 2-2 ft. It’s just not enough to push through.
We get a little bump of 4 ft swell from the east on Sunday, July 19th, but the wind is straight onshore again, making it choppy and ugly. The energy is moderate (139), but the quality is garbage. You’d be better off going for a swim.
Honestly, there’s nothing to recommend here. It’s a flat, calm period with very little wave energy. The swell is too small, the periods are short, and when there is a bit of size, the wind ruins it. For a spot that’s already inconsistent, this is a typical blank run. Don’t bother checking the forecast for a couple of weeks – it’s unlikely to change for the better.
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.
