The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Mawgan Porth. I’ve gotta be straight with you – the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long, stubborn dry spell of poor conditions ahead, but there is a light at the end of the tunnel.
The first real chance of a surf doesn’t even show up until Saturday the 15th of August. That’s a solid 12-day gap from the start of the forecast with absolutely nothing worth paddling out for. The first week is a write-off with messy, onshore winds and small, weak, short-period slop. The water temp is sitting at a touch warmer than normal for this time of year, about 65°F, so at least you won’t freeze if you’re desperate.
The standout window is the morning of Saturday the 15th. It’s not perfect, but it’s the best we’ve got. We’re looking at a clean 5ft swell from the west with a light offshore breeze from the NNE. The combined energy is moderate (295). The wave heights are getting up there, so it’s probably not ideal for beginners, but for the rest of us, it’ll be a fun session.
Then, the real gem of the entire forecast lands on the morning of Sunday the 16th of August. This is the one to circle on your calendar. Glassy conditions with a 6ft swell from the west. The wind is dead calm from the south, making for a clean, glassy surface. The combined energy is strong (374). This is as good as it gets for the whole run. For the more experienced crew, the swell is pushing into the 6ft range, so it’s got some punch. This is your best bet.
Monday the 17th of August morning still has some size, 6ft from the west-northwest, but the wind is a light cross-onshore, taking the shine off it a bit. The energy is strong (408), but the surface won’t be as clean as Sunday.
So, to sum it up: the next week and a half is a waste of time. Save your energy for the 16th of August. That morning is the standout.
Rusty.
