The Lowdown
Alright crew, Rusty here. Let's have a look at what Mawgan Porth is cookin' up for us.
Honestly, the first week or so is pretty flat and sad. We've got a real dry spell on our hands, with no decent surf on the cards until we get a glimmer of hope way, way down the track. Hang tight, because the wait is a long one.
Starting out on Monday the 24th, it's barely a ripple. You're looking at ankle-snappers around 0.7ft with a weak 17 combined swell energy. The wind is offshore and clean, but there's just no water moving. This poor excuse for surf carries on through Tuesday the 25th, where we finally see tiny 1.6ft to 2ft waves kicking up a bit more energy to 64-85. Still, it's only worth it if you're desperate for a paddle. Wednesday the 26th is more of the same, with the wind going cross and the swell dropping back off.
From Thursday the 27th right through to Sunday the 7th of September, the forecast is a write-off. The wind is either howling onshore or ripping cross-shore, and the wave quality is just poor, lumpy, and messy. The swell does push up, hitting 8.2ft on the 28th and 31st, but it’s accompanied by brutal onshore winds making it unrideable. A massive 1080 combined swell energy on the 31st is useless when it's blown out. There are a few cleaner moments on the 2nd and 3rd of September with 4.6ft to 7.2ft swell and a light cross-off wind, but the wave energy is still on the low side for the size, and the whole setup screams "marginal."
Now, here's where it gets interesting and a touch frustrating. Look ahead to Tuesday the 8th of September. We've got a serious pulse of energy heading our way. The morning shows a massive 11.5ft swell from the W with a long 16-second period and a whopping 6719 combined energy. The wind is a fresh cross-shore, which could keep it somewhat clean. The guidance even says wind and tide are favorable. Problem is, for a spot like Mawgan Porth, 11.5ft is just too much. That’s expert-only territory, and even then, it's likely to be a washing machine. A real shame, because the potential is there for a proper session if it was half the size.
So, bottom line: the first week and a half is a scratch. The only true standout is a promise of serious size and power on Tuesday the 8th of September, but it's a beast that's probably too big for this break. It's a long-range hope, but don't hold your breath for a clean, rideable wave.
