Mawgan Porth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

Right off the bat, I gotta be straight with you – it’s a tough start. We’re looking at a proper dry spell. For the first ten days or so of the forecast, it’s a real struggle to find anything worth paddling out for. The swell is small, the wind is messy, and the energy is just limping along. The only real glimmer of hope in that first week is a tiny window on Wednesday the 12th.

That morning, the wind swings light and clean from the NNE at 3 mph, with a 3 ft swell from the west and a period of 10 seconds. The combined energy is reading moderate (124), and it’s clean. Then, things get really interesting in the afternoon. The wind goes dead calm – glassy – and the swell picks up just a hair to 3 ft, still from the west, with a 9-second period. The energy jumps a bit to 139 (moderate). The water is a touch warmer than normal for this time of year at 66°, which is nice. For a beginner-friendly spot like Mawgan Porth, that Wednesday afternoon is the best we’ve got. The wave quality is described as "very ordinary," but it’s clean and glassy, and that’s about as good as it gets right now. The crowd factor is "sometimes," so you might have some company, but it won’t be too bad.

After that little tease, it’s back to the grind. We get a solid run of poor surf and cross/on-shore winds from the 13th through the 22nd. The swell does bump up a bit, but the wind is always blowing the wrong way or too strong, making a mess of things. The combined energy is all over the shop, from a low 29 up to a moderate 276, but it doesn’t matter because the quality isn’t there.

Now, hold on to your leggies, because there’s a big one lurking in the distance. On Sunday the 23rd, the forecast shows a serious spike. The morning session brings a 10 ft swell from the WNW with a 9-second period. The combined energy goes through the roof – strong to very strong at 1436. But here’s the kicker: it’s a north-northwest wind at 16 mph blowing cross-shore, creating a chop. The wave comment says "marginal surf forecast," and the score is a 2. This is big, powerful, and messy. At over 8 ft, this is strictly for the experts. The afternoon drops a bit to 8 ft, but the wind shifts to the WNW, making it a cross-onshore and choppy mess. The energy is still massive at 876 (strong). This is a raw, powerful beast, not a clean, lined-up wave.

After that, things settle back down into small, wind-affected surf for the rest of the period.

So, if you're a beginner, Wednesday the 12th is your day. The morning is clean, but the afternoon is the standout with those glassy conditions. For the experienced crew, the only thing that looks like a real challenge is that Sunday the 23rd morning swell, but be prepared for a battle with the wind chop.

Rusty.
