The Lowdown
Alright, Rusty here. Let’s talk about what’s going on at Mawgan Porth.
Honestly, mate, this is a tough stretch. For the next week and a half, the wind is just relentless and the conditions are poor. We’re getting swell, but the wind keeps ruining it—onshore or cross-onshore most of the time, with speeds that can make it a real chore. There’s no point getting excited until well into the second week.
The first real chance of anything sorted looks like September 5th. It’s not going to blow you away, but it’s the best window we’ve got. On Saturday the 5th, we’ve got a morning session that’s just about worth paddling out for. A clean 4ft swell from the west (moderate combined energy of 258) and a light NNE breeze that’s cross-offshore, which is about as clean as it’s going to get around here for a while. The wave period is 9 seconds, so it’ll have a touch of shape to it. This is a river break, beginner-friendly, and being clean is a big positive.
After that, it drops off fast. By the 6th, the swell fades to tiny 2ft and the wind switches. Then we get a patchy run through the 7th to the 10th with small, messy, or onshore conditions. Nothing worth chasing.
The water is sitting at 65°F, which is a touch warmer than normal for this time of year—about 3° above average. It’s noticeable, but not crazy.
So there you go. The morning of September 5th is the pick. One clean window in a long, windy forecast. Hang in there.
