The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Mawgan Porth.

Right off the bat, I gotta be straight with you – the next week and a half is a real struggle. We’ve got a long stretch of weak, choppy, and downright poor surf. The session on Monday the 27th is a no-go with a tiny 3ft cross-on swell from the WNW and only 8 seconds of period. The wave energy is weak at 198, and it’s just not worth paddling out. The water is a touch warmer than normal at 65°F, but that’s the only nice thing I can say.

The whole week through to the 9th of August is littered with small, short-period swells under 3ft. The wind is mostly cross or onshore, keeping things messy. There’s a glimmer of clean conditions on the morning of the 3rd of August with a cross-offshore wind, but the swell is a weak 4ft from the north with a period of just 6 seconds. The energy is moderate at 111, but it’s the only day that’s described as "surfable but very ordinary." It’s desperate.

Then, just when you think it’s all over, a pulse shows up. Sunday the 9th of August brings a proper swell. The afternoon sees a 6ft groundswell from the WSW with a very long period of 11 seconds. The combined energy is a strong 944. The problem? The wind is onshore, and the forecast calls it "poor surf conditions." That’s a real shame. The swell direction is WNW, which is the optimum direction for this river break, but the wind is just ruining it.

The best of a bad bunch looks like Monday the 10th of August. The morning shows a 7ft swell from the west with a 10-second period. The energy is a strong 884. It’s a solid swell, but it’s on the bigger side—over 5ft, so it’s not for beginners. The wind is a stiff cross-onshore from the NNW, which will chop it up. This is a beach-and-river setup, and with that much size and onshore wind, it might actually be more interesting for the kite surfers than us paddle guys. The afternoon is similar at 6ft. It’s powerful, but it’s not the clean, glassy surf we dream of.

For a true standout, we have to look at Tuesday the 11th of August. The morning brings a 5ft swell from the west with a 9-second period, and the wind is a light cross-onshore from the WNW at only 6 mph. The energy is moderate at 375. It’s the only time in the whole window where the conditions are described as "marginal" rather than "poor," which is a small win. It’s the most promising window, but it’s still a long way off, so don’t get your hopes up too much yet.

So, to sum it up: there’s a long, dry gap until the 9th of August. The only real standout is the morning of the 11th of August, with a clean 5ft swell. It’s not perfect, but it’s the only surfable option on offer. Keep your eyes on the forecast, because this one might clean up.

Rusty.
