The Lowdown
Alright, grab a coffee and settle in. It’s looking like a real quiet spell for Kennack Sands. There’s a big gap of nothing much on the cards, so don’t rush to wax your board just yet.
For the first week and a half, it’s a bit of a non-starter. From the 30th of July right through to the morning of the 8th of August, the swell is tiny or non-existent. We’re talking ankle-biters at best, with the combined energy barely registering (3). The water temp is sitting at 67°, which is *much warmer than normal* for the time of year; that’s over 5° above average, so it’s a proper anomaly.
The first glimmer of hope comes on Saturday morning, the 8th of August. A small push of swell from the SSW bumps the height up to about 4ft with a period around 7 seconds. The combined energy climbs into moderate territory (111). Wind is light and cross-offshore from the west, so the surface should be clean. It’s still only rated as “surfable but very ordinary,” so don’t expect any gems. Kennack Sands is a sheltered spot, inconsistent, and best with a solid SSW swell to work. It’ll be one for a longboard and a patient attitude.
The next notable window is around the 12th of August. We see swell heights around 4ft to 5ft from the east, with the energy swinging up (122 and 157). The wind turns offshore or clean cross-off on the 13th of August, with a fresh offshore from the WNW. The period is on the shorter side (6 to 7 seconds), so the shape won’t be groundswell quality, but it’ll be rideable. Given the size (over 4ft), it’s starting to push out of beginner territory.
If you’re looking for the standout, it’s that Saturday the 8th morning session for the cleanest wave with the most potential, but honestly, the whole 16 days is a grind. It’s one of those long, drawn-out flat spells. The forecast can always change, but right now, it’s a waiting game.
