The Lowdown
Alright folks, Rusty here. Let’s talk about Kennack Sands. Gotta be straight with you – for the first week and a half, it’s a real struggle. The water is a toasty 68°F, which is much warmer than usual for this time of year, but that’s about the only good news. We’re looking at a solid gap of nothing rideable from now until the end of July. The swell is tiny, barely a ripple, with combined wave energy down in the low single digits (4, 3, 2). It’s flat, flat, flat.
Then we roll into the first few days of August, and it’s still a write-off. Cross-onshore winds and lumpy conditions keep the score at zero. The wait continues.
Finally, things start to get interesting around the 5th of August. A bigger pulse of swell shows up, but it’s messy. On Wednesday morning, we’re looking at 8ft of east swell with a short period of 8 seconds. The combined energy jumps right up to (737), but the wind is cross-offshore and kicking up at 18 mph. That’s powerful, but it’s a raw, chunky beast. This is expert-only territory – way too big for beginners. The period is short, so it’ll be a bit lumpy and sectiony.
The best of the bunch, the true standout, is the morning of Thursday, the 6th of August. We’ve got a solid 8ft east swell, still with that 8-second period, and the wind swings offshore from the NNW at 15 mph. That’s clean, offshore conditions. The combined energy is still strong at (669). It’s still a big wave for this sheltered spot, so only for experienced surfers, but the offshore wind will make it look a lot better than the days before. It’s a narrow window, but that’s our best shot.
The rest of the forecast after that fades back into small, weak surf with fresh onshore winds. So, if you’re after a wave, pencil in that Thursday morning, 6th of August. Before that, don’t bother.
