Mawgan Porth Surf Forecast and Surf Report

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

First up, fair warning – we’re looking at a long stretch of quiet to poor conditions before anything really gets going. The water is sitting at 67°, which is a good 4° warmer than usual for this time of year; nice for a paddle but it doesn’t bring any waves with it.

From Sunday the 16th right through to Thursday the 27th of August, it’s pretty much a write-off. You’ll see small slop in the 1ft to 3ft range, but with periods under 8 seconds and a lot of cross and onshore wind, it’s just not worth suiting up. The combined energy stays low, often between 10 and 139, so there’s hardly any push. The onshore winds mid-week (18th-20th) pick up to 19 mph or so, with solid rain showers on Thursday and swell building to 7ft – but that’s just messy, lumpy, blown-out stuff.

There’s a tiny glimmer on the morning of Saturday the 22nd and Sunday the 23rd, when a light cross-offshore from the NNE and NE cleans things up, but the swell is only 1ft to 2ft with an 8 to 10 second period. Pretty much flat, even if the ocean looks neat.

The real blank patch runs from about the 24th to the 27th – we’re talking tiny waves, 0.3ft to 1.0ft, with some glassy moments on Thursday the 27th morning under a light W breeze. But still, no real surf.

Alright, now for the one stand out in the whole forecast. It’s a long way off, mind you. On Friday the 28th of August, the morning session looks like the pick of the bunch. You’ve got a clean sky, light 6 mph SSW breeze clipping it cross-onshore, and a 6ft swell from the WSW with a 9-second period. The combined energy hits 453 (moderate), so there’s some proper weight behind it. This one is a beginner-to-intermediate kind of size – nothing too scary, but enough to get a decent ride. The trade-off is that wind is just a little cross-onshore, so expect a few ripples on the face, but it’s still the best we’ve got over the whole run. After that, it gets lumpy again under a fresh NW wind on Saturday the 29th, with the swell holding around 6ft but the energy climbing to 750 (moderate). It’ll be choppy, though – not the clean lines you’d hope for.

Real talk: if you’re itching for a wave, that Friday the 28th is the only serious shout in the whole outlook. Everything else is flat or blown out. Keep an eye on the long range – it can shift, but right now it’s a quiet spell for Mawgan Porth.
