The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Kennack Sands over the next couple of weeks.
Straight up, I gotta be honest with you – it's looking pretty bleak. We've got a massive 16-day window here, and there's virtually nothing to get excited about. The whole forecast period is a long, flat spell. From now right through to the end of the 16 days, the wave energy is either zero or a measly little number in brackets (5), (8), (4) – it's all weak, pathetic energy. The swell height barely registers, just a tiny 0.3 ft here and there. There are no standouts, no hidden gems, nothing. For a spot like Kennack Sands, which is already inconsistent, this kind of blank run isn't totally out of the ordinary, but it's still a tough one to swallow.
If you're desperate for a paddle, the only tiny blip comes on the 18th of September. There's a bit of a long-period groundswell from the south, with a 0.3 ft swell and a period of 18 seconds. At a sheltered spot like Kennack, that long period might help it wrap in slightly better than nothing, but honestly, it's still tiny. The wind is offshore from the WNW, which is clean, but it's a fresh breeze at 22 mph, so it'll be a battle to stay out. The energy is still weak (12). There's nothing here for the 15th of September either, despite the glassy conditions – the swell is just too small.
So, in short, the surf is poor. The water temperature is about average for the time of year, so no surprises there. Keep the board in the car and the wax in the wrapper. This one's a write-off.
