The Lowdown
Alright folks, Rusty here, checking in on the Cornwall scene. Let's be straight with you, this forecast is a grim one for the next couple of weeks. We’ve got a serious flat spell settling in.
Looking at the whole picture, it’s a tough run. The next decent session doesn't show up until Thursday the 13th of August. We’re looking at a solid week of nothing worth paddling out for before that, and even after, the windows are small.
Let’s break it down.
For the first few days, forget it. Tuesday the 11th and Wednesday the 12th are a write-off. The swell is tiny with a weak energy (9 to 178 range) and the onshore winds are just chopping it all up. Not worth the wax job.
Now, Thursday morning, the 13th of August, we finally get a little window at Falmouth – Swanpool. It’s not a classic, but it's the best we’ve got. A north-northwest offshore wind is blowing, which is a major positive—that’ll clean it right up. We’re looking at about 4 ft of swell from the west-southwest with a period of 11 seconds. The combined energy is moderate at 351, so there’s a bit of push, but these are beginner-friendly waves. The water temp is about average for the time of year, so nothing unusual there. Keep in mind this spot can get crowded, so get out there early if you want a piece. The swell drops off hard by the afternoon, back to ankle-biters.
After that brief tease, we’re back to the doldrums. From Friday the 14th right through to Tuesday the 26th of August, it’s tiny. Knee-high at best, with most days showing 0.3 ft to 1 ft and pathetic energy readings in the single digits and teens. The winds are all over the place but it doesn't matter because there's no swell to work with. We even get a long period (12 to 18 seconds) on the 15th and 16th, but it's so small it’s just a ripple. For a beach break like this, that long period would make it even harder to link up anyway.
Honestly, if you’re absolutely desperate, Thursday the 13th morning is the only time to even think about it. Otherwise, this looks more like a stretch for a longboard or a paddle than a surfboard.
Stay tuned, it’s bound to change eventually.
Rusty.
