The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for the next couple of weeks down at Mawgan Porth.
Right off the bat, I’ve gotta be straight with you – it’s a grim picture. The first week and a half is a write-off for any decent surf. The swell is tiny, the wind is all over the shop, and there’s just no energy in the water. We’re looking at a long, dry gap from now until the middle of the second week. There’s a hint of something on Wednesday the 12th, but it’s nothing to get excited about.
The only real standout, and I’m using the term loosely, falls on Sunday the 16th of August. For the first time in a long while, we get a clean, offshore breeze from the ENE blowing at 9 mph, and the swell bumps up to 2 ft from the WNW. The combined energy is a moderate 171 (moderate wave energy), and the period is a short 6 seconds, so it will be a bit lumpy and crumbly, but at least it’ll be clean. This is your best bet for a paddle, but keep your expectations low. It’s still a fairly ordinary session.
For the rest of the run, the wind is a mess. Through the first week, we’ve got strong onshore and cross-onshore winds, especially from Wednesday the 5th through to the 9th, with swell poking up to 5 ft but blown out completely. That’s not surfable for a paddleboard; it’s more of a kite-surfing setup if you’re into that sort of thing. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, but that’s about the only thing that’s working in our favour.
So, to sum it up: it’s a lean spell. Sunday the 16th is the pick of a very poor bunch, but don’t hold your breath. The forecasts can always change, so keep an eye on it, but for now, I’d be finding something else to do.
Rusty.
