The Lowdown
Alright, Rusty here. Let's talk about what's brewing for the next couple of weeks.
Honestly, folks, it's a tough stretch for Maenporth. We're looking at a long dry spell before anything even thinks about showing up. The water is a touch warmer than normal for this time of year, sitting at 66°.
For the first six days, from Thursday the 6th right through to Tuesday the 11th, it's a complete write-off. We're talking ankle-snappers at best, with swell heights barely reaching 1ft. The wave energy is pitiful, with a combined energy reading of just 9 (out of who knows what) on the Monday morning. It's flat, pure and simple. The wind is mostly offshore or glassy, which is a tease, because even if there was a wave, it would be clean, but there just isn't. You'd be better off finding a lake.
Things start to show a flicker of life on Wednesday the 12th. The swell picks up to a modest 3ft out of the WSW, with a period of 10 seconds. But the wave energy is still very low, with a combined energy reading of 167 on the Wednesday morning. The wind is light and clean, which is a bonus, but it's still a far cry from good surf. The "poor surf conditions" tag is a dead giveaway. This pattern of small, weak swell continues through the 13th, with a bit more energy (up to 203) but still well under 3ft.
After that, it's back to the doldrums. From the 14th all the way through to the 21st of August, the swell drops right back to a pathetic 0.3ft. The wind shifts around, but it doesn't matter because there's no wave to ride. The energy readings are all in the single digits or low twenties. There's a long-period groundswell peeking in from the south on the 17th, with a period of 18 seconds, but the height is only 0.3ft. It's a ghost.
So, the bottom line is that there are no standout options here. Maenporth is a sheltered, inconsistent beginner spot, and for the entire 16-day window, it's not delivering. Sometimes you get a blank run like this, and it's just part of the game. The forecasts can change, but as it stands, leave the board in the shed.
Rusty.

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.
