The Lowdown
Alright folks, Rusty here. It’s a bit of a flat spell on the horizon for us at Kennack Sands, so let’s not beat around the bush.
We’re looking at a real quiet run for the next couple of weeks. The ocean’s basically taking a nap. For the first several days, through the coming weekend and into the start of next week, there’s just nothing rideable. You’ll be staring at a lot of calm, empty water, which is a tough look for this place. The swell window is just shut.
Now, things do try to pick up a little around the middle of the month. On the 12th of August, we see a little pulse of easterly swell. It’s not big, around 3.6ft to 4.6ft, but the problem is the wind. It’s blowing onshore and lumpy, so that surf is going to be a messy, choppy mess. Honestly, with that setup, this exposed stretch looks more interesting for the kite crew than for us paddle surfers. That’s a hard pass from me.
There’s a bit of a shift later in the month, around the 19th and 20th of August. We’ve got a long-period SSW groundswell starting to show up. But it’s tiny, only about 0.7ft. The energy is there in the water, but it’s just not translating to any real height at the beach. The wind does go offshore and clean, which would be great if there was anything to ride, but there just isn’t. It’s the classic tease.
This is a pretty normal blank run for this spot. It happens. Forecasts can always change, but as it stands, if you want a surf, you’re probably better off finding a pool. Water temp is sitting around 66.4°, which is a touch warmer than usual for this time of year, so at least the wait will be comfortable.
Hang tight. There’s no standout, no hidden gem in this window. Sometimes the ocean just says no.
