The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Kennack Sands over the next couple of weeks.
We’ve got a long dry spell ahead, I’m afraid. The forecast shows no surf worth paddling out for from now until the morning of Tuesday, 13th August. That’s a solid gap of over a week of flat, small, or messy conditions. The water is sitting at 67°F right now, which is much warmer than normal for this time of year – that’s a standout in itself, but it won’t help the waves.
The first real sign of life shows up on the morning of Tuesday, 13th August. We’ve got a solid 10ft of east swell rolling in, with a period of 8 seconds. The combined energy is a strong 916, so there’s plenty of power behind it. The wind is light and offshore from the WNW, which will keep the surface clean. However, that’s a big wave for a beginner spot, and the short period means it’ll be a bit walled up and dumpy on the beach. This is one for the experienced crew only. The afternoon drops to 8ft, still decent, but the energy is still high at 578.
The morning of Thursday, 14th August, is still worth a look. We’ve got 6ft from the east, period 7 seconds, and a light offshore breeze from the WNW. The energy is moderate at 290. It’s smaller than the day before, but still clean and surfable. The afternoon drops off to 3ft and gets a bit more cross-off, so morning is the call.
Honestly, the standout here is the morning of Tuesday, 13th August. If you’re an expert, that’s your window. It’s a big, powerful, clean swell, but it’s not a beginner wave. For the rest of us, the morning of Thursday, 14th August is a more manageable option. Everything else in the 16-day window is flat or tiny.
Rusty.
