The Lowdown

Alright folks, Rusty here. I've had a good look at what's coming up for us, and I gotta be straight with you – it's a tough stretch. We've got a 16-day window ahead, and for the most part, it's a story of wind and messy conditions. The first real chance we get at something worthwhile isn't until we're well into the second week.

Looking at the whole picture, the first week to ten days are basically a write-off. From Friday, the 28th of August, right through to the 7th of September, it's a parade of strong onshore and cross-onshore winds and lumpy, blown-out surf. The swell energy does build, hitting a massive 1872 at one point, but it's accompanied by a strong breeze right on it. That's just a washing machine for a small river break like this. It's not worth paddling out for.

The one true standout, the only glimmer of hope in this whole outlook, is the morning of the 8th of September. Let's talk about that. It's not big, but it will be clean. We're looking at a tiny 2 ft swell from the west with a light north-easterly breeze. The wave energy is weak at 54, but the description is "clean." That's the buzzword. For a river break like Mawgan Porth, that cross-off wind is a gift. It'll be small, glassy and fun on a longboard. Honestly, given the stormy mess before and after it, if you get a window that morning, go. It's a rare moment of calm.

After that, the 9th and 10th of September look completely wild again. We've got a 10 ft groundswell predicted for the morning of the 10th, with a period of 9 seconds and a near gale on it. That's big and dangerous, not for a river mouth. Then the 11th and 12th fade out into nothing much at all with strong, messy winds. It's a tough outlook, but keep an eye on that 8th of September – that's your best bet.

Rusty.
