The Lowdown
Alright folks, Rusty here. Let’s be straight with you – it’s a tough stretch ahead for this corner of the coast. We’ve got a long, dry spell of tiny surf before anything even thinks about showing up. Hang in there.
The first real option I can see is a couple of weeks out, on Wednesday the 19th of August. Up until then, it’s pretty much flat. We’re talking a solid 12-day gap of nothing worth paddling out for. The water temp is a touch warmer than normal for this time of year, sitting at 66°F, but that’s about the only highlight.
So, let's cut to the only window that has a pulse. On Wednesday afternoon, the 19th of August, we’ve got a spike of energy coming into Maenporth. The swell jumps up to 8ft from the WSW with a period of 8 seconds, and the combined energy reading is a solid 611 (moderate wave energy). That’s a bit of a lumpy, short-period groundswell. Now, 8ft is getting into expert territory – it’s going to be a handful for the beginners, that’s for sure. The wind is from the NNW at 12 mph, which is offshore, so the face should be clean, but that short period means it’s going to be a bit walled-up and tricky. Maenporth is a sheltered spot, and it’s inconsistent to begin with, so you’re playing the waiting game for a set. It’s marginal, but it’s the only game in town.
Then, on Saturday the 22nd of August, we get another shot. The morning shows 7ft from the WSW, period 9 seconds, with a combined energy of 696 (moderate wave energy). Afternoon pushes it to 7ft from the same direction, period 9 seconds, and energy jumps to 734. That’s a stronger, longer-period swell. The wind is WNW at 16-19 mph, which is cross-offshore, keeping it clean. Again, 7ft is for the experienced crew only. The crowd potential is there, as it's 'often' busy, but with this much swell, it might thin out the pack a bit.
If you’re an expert, the 22nd of August is the standout. The swell is bigger, the period is better, and the wind is solid. The 19th is a promising but less certain early look. For the rest of the 16 days, it’s a flat, sad affair. Don’t bother checking the cam until then.
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.
