Mawgan Porth Surf Forecast and Surf Report

Alright, let’s cut through the noise. If you're looking at Mawgan Porth, the first week and a half is a total loss. From the 14th through the 20th, we’ve got cross-onshore winds, lumpy, choppy conditions, and waves that just have no shape or power to them. We’re seeing size – 3.5ft up to 7ft – but it’s all over the place with short, weak periods. The combined energy gets strong, hitting 913 on the 16th and even 1118 on the 18th, but it’s all messy, closing out, and not worth your time. The water is a touch warmer than normal at 64.2°, which is nice, but it doesn’t make the slop any more fun.

Here’s the good news. The 21st rolls in, and the wind finally drops to glass. Monday morning, we’ve got a clean 3ft W swell with a 13-second period. That’s a proper groundswell, clean face, light winds. This is the first real highlight. Then the 22nd, Tuesday, we get a 4ft W swell, cross-offshore SE winds, and clean conditions. Another good window.

But things stay modest. The 23rd is surfable but nothing special. On the 24th, we get a small, clean pulse – about 2ft from the WNW with a super long 18-second period and offshore ESE winds. It’s tiny, but it’s clean. The 25th has a bit more size, but the wind kicks up again. The standout, though, the one I’d wake up early for, is the morning of the 28th. We’ve got a small 3ft WNW swell, but it’s glass, 5 km/h winds, clean as a mirror. The energy is weak at 116, so it’s small, but it’s perfect. For a longboard or a funboard, that’s the session.

The 29th looks like it’s fading, with a 5ft WNW swell and a 12-second period, but the wind is on it, and conditions are uncertain. It’s promising but a long-range call, so don’t pencil it in just yet.

One thing to keep in mind: all this swell is coming from the W or WNW, which is the right direction for this break. But those shorter periods (7-8 seconds) early on are junk – just windswell. The longer ones (12-13 seconds) have the better shape. Since this is a river mouth, the long-period stuff might not peel perfectly, but with clean winds, it’ll still be fun.

So, in short: the next week is a write-off. Save your energy. Then, from the 21st through the 24th, there’s some clean, glassy potential, but the real winner is the 28th morning – small but perfect. After that, we wait and see.

Stay stoked.
