The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer down at Kennack Sands.
Honestly, I’ve got to be straight with you – the next 16 days are a bit of a tough one for Kennack Sands. We’re looking at a long stretch of flatness or very poor surf right through to at least the 10th of August. The first 12 days are a write-off for any kind of decent wave. There’s a tiny bit of energy showing here and there, but it’s all under 0.3 ft and the combined swell energy is practically nothing (3-4). It’s not going to get you out of bed.
The first real change comes on Monday the 10th of August. The morning shows a pulse of 2 ft swell from the south with a short period of 5 seconds. The combined energy is a weak 27. It’s not big, and the period is short, so it’ll be a bit on the soft and weak side. The wind is offshore from the NW at 22 mph, which will clean it up, but that’s a fresh breeze – it’ll be a battle to keep your line. Because it’s an inconsistent spot, you could be waiting a while for a half-decent wave. It’s not a winner, but it’s the only thing we’ve got.
The water temperature on the 28th of July is sitting at 68°F, which is a full 5°F warmer than normal for this time of year. That’s very unusual – you’ll be comfy in a shorty or even a spring suit.
The standout? There isn’t a true standout in this window. The morning of the 10th of August is the only time you’d even bother looking, but it’s a long way off and the quality is poor. If you’re desperate for a paddle, that’s your window. For the rest of us, it’s a good time to check the forecasts again in a few days.
Rusty.
