The Lowdown
Alright, Rusty here, and I’m looking at the same stretch of coast. The truth is, it’s a bummer of a forecast. We’re staring down a long, dry spell with almost no surf in the water for the next week and a half.
It’s a tough one. From now until the end of July and into the very start of August, it’s dead flat. Day after day with zero swell. The wind is often clean, offshore even, but with nothing to push, it’s just a glassy lake. That’s a long time to wait for a wave. For a spot like this, a blank run like this isn’t unusual, but it doesn’t make it any easier.
The only real event on the calendar is the morning of Monday, August 3rd. Kennack Sands will see a south-southwest swell bump up to about 4ft. It’s a short-period swell, around 6 seconds, so it’s not going to have much shape. The combined energy is moderate (111). But the wind is going to be howling from the south at 18 mph, right onshore and cross-on. That’s going to chop it up and make it lumpy. The water is a very unusual 67°, much warmer than normal, but that’s the only highlight. It’s small, messy, and blown out. With that wind and a beach break, that setup is more for the kite surfers than anyone looking for a clean wave.
After that, the 4th is a washout, and then it’s back to nothing. There’s no standout session here. The best bet is to wait for the next forecast.
Rusty.
