The Lowdown
Right then… Rusty here, and I gotta be straight with you. Looking at the 16-day window for Maenporth, there’s a whole lot of flat and junk to wade through before we see anything that gets the heart pumping. For the first week and a half, this is a write-off. There’s nothing from Thursday the 16th through to the final week of July that’s worth paddling out for, just tiny dribbles and onshore chop. A solid ten-day drought of poor surf conditions. You can forget your board for a while.
The only spot in the game is Maenporth. It’s a sheltered beginner spot, but it’s inconsistent and can get crowded. The water is sitting at 65°, which is much warmer than normal for this time of year – a solid 4° above what you’d expect.
Now, the real story kicks off on Wednesday the 30th of July. Come Thursday morning the 30th, we get a small bump of 3ft from the SSW with a short period, but the wind is cross from the NE at 15 mph, making it choppy. Not the one.
But then… Thursday afternoon the 30th is the standout. A proper clean window. Swell jumps to 4ft from the SW, period sits at 8 seconds, and the wind goes cross-off from the NNE at 9 mph. The combined energy hits 210 (moderate energy), and with that clean face, it’ll actually be rideable. The swell direction is a good match for the optimum SSE. It’s a short period swell, so it won’t have a ton of grunt, but for a break this sheltered, that’s fine.
Then Friday the 31st of July morning builds on it: 5ft from the WSW, period still 8 seconds, wind clean and cross-off from the N at 15 mph. Energy is up at 308 (moderate energy), and the afternoon stays clean with offshore NNW wind. That Friday is your best bet – the swell holds size and the conditions stay clean. It’s still under 5ft, so good for most who are comfortable on a shortboard. Crowds are often an issue here, so expect company.
The final day on the 31st afternoon holds that 5ft swell with offshore wind, making it another solid call. Nothing massive, but after ten days of flatness, this is the real green light.
Take it and go. Don’t sleep on that end of July window.
Rusty.

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.
