The Lowdown
Right then, let's have a look at what's on the cards for the next couple of weeks.
Honestly, I’m looking at this and it’s a bit of a tough one. The forecast is showing a whole lot of "poor surf conditions" across the board, which is a real shame. The wind is just not playing ball for most of the period, and it’s going to be a struggle to find anything clean. Water temperature is sitting at 65°, which is a solid 4° warmer than usual for this time of year, so that’s a bit of a treat if you’ve got the right rubber.
The first real chance of something decent doesn't show up until Thursday the 25th of September. We’ve got a long stretch of lumpy, choppy, cross-onshore junk before that. From the 10th right through to the morning of the 25th, it’s pretty much a write-off. The wind is just too strong, too onshore, or both, and the rideable swell that does show up is going to be a mess.
Now, on that Thursday the 25th, we finally get a bit of a break. Mawgan Porth is the only game in town. The morning session is looking like the pick. We’ve got a 6ft swell rolling in from the W, with a period of 8 seconds. The wind is swinging around to a light S, which is cross-shore, so it’s not ideal but it’s a whole lot better than what we’ve been dealing with. The water will be a bit lumpy, but it’s the only window that’s even close to rideable. The combined energy is moderate at 337, so there’s some push there. It’s a bit of a marginal call, but if you’re desperate for a paddle, this is your moment.
The afternoon on the 25th stays similar, 4ft from the W, but the wind shifts to a moderate SSW cross-shore, and the quality drops back into the poor category. The energy is still there at 333, but it’ll be a bit more of a chop-fest.
So, the stand-out, if you can call it that, is that Thursday morning. It’s nothing to write home about, but it’s the only chance we’ve got for a surf in the next 16 days. Don’t get your hopes up for anything clean or glassy. It’s a case of making the most of the least worst option.
