The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day window for the region, and I’ll be honest, it’s a tough one.
The overall pattern is grim. We’re looking at a long dry spell with nothing worth paddling out for. The first real chance of any surf is a tiny blip on Thursday afternoon, the 6th of August, but it’s a sorry 0.7ft of swell from the SSW with a short period of 6 seconds and almost no energy (3). That’s not a session, that’s a flat spell mocking you. After that, we’ve got a gap of several days with nothing recommended, just clean but flat conditions.
The first proper mention of any swell comes on Tuesday the 11th of August, but it’s a messy onshore deal with a 2ft to 3ft ESE swell at a terrible 4-second period. The energy is weak (11-32), and you’ll be fighting a cross-onshore wind. Not worth it.
Wednesday the 12th of August sees a bit more size, with 3ft ESE swell, but that period is still a pathetic 5 seconds, and the wind is a fresh cross-onshore, making it lumpy and choppy. The energy hits 60, which is still weak, and the surf quality is poor. This setup is honestly more interesting for kite surfing than paddle surfing.
The only slight glimmer in this whole window is Thursday the 20th of August. We’ve got a 0.7ft SSW swell arriving with a very long period of 14 seconds (groundswell), and the energy is a bit better at 19. The wind is light and cross-off, so it’ll be clean. But this is a long way out, so treat it as promising but less certain. The swell is tiny, so it’s really only for the most dedicated soul surfer on a longboard.
Now, a word on the spot. The only break in the entire forecast is Kennack Sands. It’s an inconsistent, sheltered beginner spot, and it’s exposed to a SSW swell, which is exactly what that tiny pulse on the 20th is coming from. The water temperature is sitting at 67°F, which is much warmer than usual for this time of year – a solid 4°F above the norm. That’s notable, but it won’t help the waves.
Truth is, there are simply no good surf options in this 16-day window. This is a blank run, and for a sheltered spot like Kennack Sands, that’s pretty normal.
Rusty.
