Mawgan Porth Surf Forecast and Surf Report

Right, let’s have a look at the next couple of weeks for Mawgan Porth. To be straight with you, the finder’s come back with nothing that’s really going to get the heart racing. It’s a fairly bleak run of small, weak surf for the most part, with a lot of onshore or cross winds messing up what little there is. The water’s sitting at 65°F, which is a touch warmer than normal for this time of year, so at least you won’t need the thickest suit.

We start off this Friday the 7th and through the weekend with nothing but knee-high slop. The swell’s tiny, around 0.6ft to 1ft, with short, weak periods of 8 or 9 seconds, and the energy is feeble, sitting in the 15 to 25 range. Friday afternoon has a cross-on breeze, and while Saturday morning cleans up a touch with a cross-off, it’s still just not doing anything. Sunday’s the same story – light wind ripples and no power. There’s a small window Saturday afternoon with an offshore breeze, but the swell’s only 0.6ft, so it’s not even worth paddling out for.

Monday the 10th and Tuesday the 11th are more of the same, with the swell never getting above 1ft and the energy staying well under 40. The winds are either cross or cross-off, but the lack of any real swell makes it a non-event. It’s just a flat, frustrating stretch.

We finally see a bit of a pulse mid-week. Wednesday the 12th kicks up to 3ft with a slightly longer period of 10 seconds, and the energy jumps to 125, which is the first sign of any moderate wave energy. The wind is a clean cross-off, so it looks tidy, but it’s still small and pretty weak. Thursday the 13th afternoon sees the swell nudge up to 4ft with a period of 10 seconds and energy of 237, but it’s got a cross-on wind, so it’s going to be chopped up. Friday the 14th is a bit bigger at 3ft but with a cross-shore wind and a shorter period, making it messy.

The weekend of the 16th and 17th is a mixed bag. Saturday the 16th has a tiny, glassy morning with a 2ft swell, but the period is a dismal 5 seconds, so it’s just not going to break properly. Sunday the 17th morning is the first time we see something that could be considered rideable: 4ft at 10 seconds, with energy of 328. But again, it’s cross-shore and only rated as marginal. It’s the best of a bad bunch, but it’s not a standout by any stretch.

Monday the 19th sees the biggest swell of the period, with 6ft to 6ft on Wednesday, with energy in the 400s. But the period is only 8 seconds, and the wind is cross or cross-off. It’s got some push, but it’s going to be a lumpy, sectiony mess, not the clean groundswell we’d want. The size is getting up there too, over 5ft, so it’s not for the beginners.

The real standout, if you can wait, is Thursday the 20th morning. The swell is a solid 6ft, the period is 8 seconds, and the energy is 383. But the key is the wind: it’s glassy. Dead flat calm. That’s the one window where it’s going to be clean and have some size. It’s still a short-period swell, so it won’t be perfect, but it’s the pick of the two weeks. The afternoon gets a cross-on breeze and drops a bit.

Friday the 21st has a similar story, with 4ft and a clean cross-off wind, but it’s not quite as good as Thursday morning. After that, it fades out with fresh cross-off winds on the 22nd, but the energy is dropping back down.

So, if you can hold out, Thursday the 20th morning at Mawgan Porth is your best shout – just for a few hours of clean, glassy surf. It’s a river break, and this is a fairly consistent spot, so it tends not to stay flat for long. For the rest of the time, you’re probably better off finding something else to do. The swell direction is W to WNW, which is about right for this place.

Right, that’s the long and short of it. It’s a waiting game, but there’s a glimmer there.

Rusty.
