The Lowdown
Gutted, folks. I’ve been staring at the charts for Kennack Sands, and it’s a tough one. We’ve got a solid 16-day window stretching from September 5th right through to the 20th, but to be straight with you, the surf is looking pretty ordinary for most of it. That first Saturday morning (Sept 5th) will be glassy with the water at 64°F, which is a touch warmer than normal for this time of year, but there’s just nothing out there. The swell energy is weak (18), and we’re scraping the bottom of the barrel with a dribble of 0.6ft.
Honestly, the first stretch is a write-off. From that initial Saturday, we’re looking at a run of poor conditions for the next four or five days. The swell stays tiny, and we’ve got some cross and cross-off winds messing with what little is there. The combined energy is just pitiful for most of it. There’s no point sugar-coating it; you’d be better off doing something else.
The first real, and I mean *real*, flicker of life doesn’t show up until Monday, September 14th. The wind finally eases off, going light and clean, and we see a slight bump in the swell. It’s still small—around 3ft to 3ft—but it’s coming from the ESE with a short period of 5 seconds. The energy is still on the low side (28 to 48), but it’s clean. It’s not going to be world-class, but for a sheltered spot like this, it might just be rideable. Tuesday the 15th looks a touch better with the same size and glassy conditions in the morning, which is a big plus.
But even that is a fleeting tease. By Wednesday the 16th, the swell fades again, and we're back to tiny dribbles and increasingly fresh winds. From the 17th onward, it’s a dead loss again. Forget it.
The upshot is, out of these 16 days, the only thing that even comes close to a surf is that Monday and Tuesday around the 14th and 15th. And I’m using the term “surf” loosely. This spot is inconsistent at the best of times, but this is a particularly blank run. When it’s this small and the winds are up, this beach setup looks far more interesting for a kite surfer than for a paddle surfer. There are just no decent waves on the cards. The forecasts can change, but as it stands, I’d be looking at other options or taking a long walk.
Keep the faith, but don’t hold your breath.
