The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Mawgan Porth.
To be straight with you, the next week and a half is a bit of a write-off. The wind is howling onshore from the southwest and west, and the swell is all messy. We’re looking at a solid run of poor conditions from Tuesday the 1st all the way through the 8th of September. The swell energy is there, especially on the 7th and 8th pulling in some serious numbers (1013 and 1416), but it’s all wind-chopped and lumpy. Not worth paddling out for.
There’s a potential glimmer on Saturday the 5th. The morning glass-off with an easterly breeze at just 3 mph is a good sign. The swell is 4 ft from the west with a 10-second period, keeping the energy moderate (238). The water is sitting at 65°, which is a touch warmer than normal for this time of year. But the waves are described as very ordinary, so it’s only a marginal call.
After that, it’s back to the struggle until we hit Monday the 14th of September. Now that’s the one to circle. You’ve got a 6 ft to 6 ft west swell with a clean 8-second period, and here’s the kicker—the wind is offshore at 9 mph straight from the east. That’s gonna clean things right up. The swell energy is moderate (362 to 435), and it’s the first time in the whole run we see “expect good surf conditions.” This is the standout in the window.
Then on Wednesday the 16th of September, another possible hit. Morning glass again (3 mph from the south), with a 4 ft swell from the west-southwest at 10 seconds. Energy is moderate (335). Conditions look good, but it’s a long way off and the swell is a little smaller.
For the most part, this is a waiting game. The wind just won’t give us a break until that second week. If you’re desperate, the 14th is the one to aim for. Keep the wetsuit zipped.
Rusty.
