The Lowdown

Right then, let’s have a proper look at what’s on the cards for Mawgan Porth over the next couple of weeks. Straight up, I’ll be honest with you – it’s a rough start. The first few days are a write-off, with a messy cross-shore and onshore wind and lumpy, poor surf. We’ve got a gap of quiet, poor conditions from the 2nd right through to the 4th. Not a single wave worth paddling for.

Then, finally, on the morning of Saturday the 5th, we get a little window. The wind drops right out – dead glassy. The swell is small, just 4 ft from the west, with a period of 10 seconds. Combined energy is moderate (289). It’s not going to be a world-beater, but for a beginner-friendly spot like this, that’s about as clean as it gets. The water temperature is 65°, which is a touch warmer than normal for this time of year, so a bit of a treat. This is the only real standout in the whole run.

After that, the glassy conditions fade on the Saturday afternoon, and we’re back into a long, frustrating gap. Sunday the 6th is tiny and weak, then from Monday the 7th through to the end of the first week, it’s a mess of strong, onshore wind and big, lumpy conditions. The swell gets bigger, hitting over 8 ft in places, but with the wind straight on it, it’s just a washing machine. Best left for the kite surfers if you ask me.

Moving into the second week, there are a few moments of promise. On the morning of Friday the 11th, we see an 8 ft swell from the west with a period of 8 seconds, combined energy rocketing to 1031 (strong). The wind is light from the NNW, which is a cross-shore, so it’s not completely blown out. It’s a tough call, but for the more experienced crew, there might be a few barrels to be had. The afternoon gets a bit bigger at 10 ft, but the wind shifts cross-on, making it messy.

Saturday the 12th morning looks interesting – a 8 ft swell from the WNW with a long 11-second period, combined energy of 1267 (strong). The wind is light from the SSE, which is a clean offshore breeze. That’s a good combo. But it’s a long way out, so keep your fingers crossed. The afternoon gets a bit more crowded with a moderate cross-shore.

The rest of the week is a mix of average to poor conditions. The 13th and 14th have some clean offshore winds again, but the swell is a bit all over the place. The 15th looks poor with onshore winds, and the 16th is a right-off with a 10 ft swell and fresh cross-onshore wind.

So, to sum it up: the one true standout is the glassy morning of Saturday the 5th. It’s small, but it’s clean and perfect for a beginner session. After that, keep an eye on the morning of Friday the 11th and Saturday the 12th for the more experienced surfers, but don’t hold your breath.
