The Lowdown
Alright, folks, Rusty here. Let's have a look at what’s on the cards for Maenporth over the next couple of weeks. I'll be straight with you – it’s a bit of a dry spell, so temper those expectations.
Right off the bat, we’ve got a long gap with no surf worth getting excited about. From now, Monday the 10th of August, all the way through to the end of the first week, the energy is weak and the wind just isn’t playing ball. The water temperature is about average for the time of year, nothing unusual there. We’re looking at a frustrating run of tiny swell with poor surf quality, and the scores reflect that. You’ll see some cross-off and offshore breezes on the 10th and 13th, but with wave heights barely scraping 2ft, it's not enough to get wet for.
The only flicker of something happens on Wednesday the 12th of August. The combined energy bumps up to a moderate 180, and we get a 3ft to 3ft swell from the WSW with a period of 9 to 10 seconds. The wind is light and cross-shore, so it’ll be a bit small and weak, but at least it’s not choppy. That’s about the best you’re going to get, and for a sheltered beginner spot like Maenporth, that’s saying something.
After that, it’s back to the doldrums. The second week is a write-off. We get a tiny spike of 5ft on Monday the 24th of August, but it’s onshore with a short 5 second period and poor quality, so you can forget it. Then on Tuesday the 25th of August, the swell jumps up to 5ft from the WSW with a 9 second period and strong combined energy of 394. But again, the wind is cross-onshore and choppy, which ruins any chance of a clean wave. It’s just too messy.
Honestly, this is a blank run for Maenporth. It’s an inconsistent spot at the best of times, and this 16-day window has nothing to offer a surfer. If you’re desperate for a paddle, Wednesday the 12th is the only day that’s even worth looking at the ocean.
Rusty.
