The Lowdown
Alright folks, it's Rusty here. Let's be straight with you – this is a tough one. We're looking at Kennack Sands, and to be honest, the next couple of weeks are a real struggle. There's a massive dry spell coming up. From now, right through to the end of July, there's basically nothing doing. We're talking a solid 10 to 12 days of flat to near-flat conditions. The water's a balmy 68°, which is much warmer than normal for this time of year, but that's about the only bright spot. You'll be staring at a lake out there.
The first real sign of life doesn't show up until Saturday, the 1st of August. We finally get a pulse of energy. The afternoon sees a 5ft swell pushing in from the ENE, with a short 6-second period, and the combined swell energy is moderate at 206. The wind is a cross-offshore breeze from the WSW, which will keep the surface clean. The waves are likely to be a bit soft and crumbly with that short period, but for a place that's been dead for so long, it's a welcome sight. This is a shoulder-high option, but realistically, it's not a standout.
The following day, Sunday the 2nd of August, the swell drops back to 3ft from the East, period still short at 7 seconds, and energy at 135. The wind holds from the WSW, so it stays clean in the morning. It's a smaller, less powerful version of the day before.
After that, it fizzles out again really quickly. From Monday the 3rd of August, we're back to tiny, weak surf. So, the only real window is that Saturday and Sunday at the start of August. It's not going to be epic, but it's the only game in town. Honestly, given the long, flat run we've just had and the small, short-period nature of the swell when it does arrive, this setup might be more interesting for a kite surfer than a paddle surfer.
Rusty.
