The Lowdown
Alright folks, Rusty here. Let’s cut to the chase. The next sixteen days at Kennack Sands are a total write-off for us surfers. I’m not gonna sugarcoat it – there’s nothing on the cards worth paddling out for. The whole stretch is a bust.
We start off with a long, dry spell. From Saturday the 25th of July right through to the 7th of August, the swell is basically non-existent. We’re talking tiny, weak dribbles of energy – the combined energy barely registers, often down at 0 or 3 (0 to 3). It’s all southerly windswell with a few seconds of period, but it’s just not enough to break properly. The winds are mostly offshore or clean, which is a tease, but with no waves to groom, it’s a cruel joke. You’ll see a few clean, glassy mornings, like the 3rd of August, but it’s flat as a pancake. That’s a solid week and a half of nothing.
The only flicker of something happens on the 8th of August. A weak SSE swell shows up, but it’s only 4ft at 4 seconds – that’s terrible, short-period windswell. The combined energy is still pitiful at 47 (weak). The wind is a light cross-shore, making it choppy and messy.
Then on the 9th of August, we get a pulse of 5ft SSW swell at 7 seconds. The combined energy jumps to 277 (moderate), but it’s still a short-period, junky swell. The wind is a light cross-shore here too. For a beginner, 5ft is already getting a bit much, and with that short period, it’ll be a bumpy, close-out mess.
So, the reality is this: there’s one day, the 9th of August, that has the most energy, but it’s not worth the drive. The break is sheltered and inconsistent, and this swell direction is the opposite of what it likes. We’re dried out. The forecasts can change, but for now, keep the boards in the van.
Rusty.
