The Lowdown
Alright, let's talk about the surf ahead. I gotta be honest, it's a bit of a tough read. The first real chance of a wave doesn't show up until the 2nd of August, and even then, we're talking small stuff.
That Sunday afternoon, the 2nd of August, Maenporth might see a little 1ft pulse from the WSW. The wind will be completely glassy, so it'll be clean as a mirror. The period is a short 8 seconds though, and the combined energy is only 41, so it's tiny and weak. A total ankle-snapper for the beginners.
The best of the whole outlook is on Monday the 3rd of August, in the morning. We get 3ft of WSW swell (113 moderate energy) and that same glassy wind. The period is 9 seconds, so it’s still a bit short, but for a place that’s normally inconsistent and sheltered, this is the one chance to get a few clean lines on a log if you have the patience. The water is at 66°F, which is much warmer than usual for this time of year.
After that, it’s a real dry spell. The rest of the first week and into the second week is flat. We get a few tiny, weak swells, but nothing that would make you paddle out.
Looking at the 8th of August Saturday, we see the most size at 5ft from the east. But the period is a terrible 5 seconds – that's just windswell slop, and the energy is only 118. For a sheltered spot like Maenporth, that’s just messy. By Sunday the 9th, the swell hits 6ft from the SW with the energy jumping to 358 (moderate), but the wind is cross-onshore and choppy. At 6ft it's too big for beginners, and the wind will ruin it. With that much chop and side-wind, this looks more promising for kiting than surfing.
Honestly, there are no standouts. The whole 16 days are pretty quiet. Your best bet is that tiny, glassy session on the 3rd of August. The rest is a normal quiet run for this area. Forecasts can change, so don't give up hope completely, but right now I’d say find something else to do.

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.
