The Lowdown
Alright folks, Rusty here. Let's have a look at what Maenporth has got cooking for us over the next couple of weeks. I gotta be straight with you – it's a bit of a tough stretch for paddlers. The water's sitting at 65°, which is a touch warmer than normal for this time of year, so at least you won't freeze while you're waiting for something to ride.
We start off on Tuesday the 25th with a weak, short-period 4ft easterly swell (148 combined energy) and a moderate onshore breeze. It's messy, and not worth suiting up for. Wednesday the 26th and Thursday the 27th are flat with only knee-high dribble, so you can leave the board in the car. There's a glimmer on Friday the 28th morning with a clean 4ft swell from the SW (205 combined energy) and a light cross-offshore wind, but the wave comment says "poor surf conditions," so it's probably soft and weak. We get a bigger pulse on Saturday the 29th – a 8ft to 8ft SW swell, wind looks okay, and the energy jumps significantly (589 to 976). That's some proper power, but that size is getting into expert territory, especially at a sheltered spot like this. The wave quality is still flagged as poor, which is a shame.
Honestly, through all of August and into the first week of September, almost every single entry is marked as "poor surf conditions." It's a real lull. There's a little clean-up on Monday the 31st with a moderate offshore breeze and 4ft swell (194 energy), but again, the quality description doesn't change. By the 2nd of September, we see some very long-period 16-second swell rolling in, but it's tiny – only 0.7ft. That's all bark and no bite.
The best bet in this whole 16-day window, if you can call it that, is probably Maenporth itself on Tuesday the 8th of September. The afternoon shows a big bump in energy with a 8ft swell from the WSW packing a solid 832 combined energy, and a clean cross-offshore wind. That's got some grunt. The downside? It's surf for experienced folks only at that size, and with that much west in the swell, it might be a bit close to the wind for this sheltered spot. The energy is strong, but the wave quality is still rated poor. It's a long way out, so don't bank on it, but it's the only thing that looks like it might have some real push.
Other than that, we're looking at a whole lot of nothing for nearly two weeks. If you're not a surfer, with those strong onshore winds on the bigger days, the setup looks more interesting for kiting than paddle surfing.
Stay patient, maybe clean the wax off your board, and keep an eye on the sky.

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.
