Alright folks, Rusty here. Let’s have a proper look at what’s coming down the line for us. I’ve got to be straight with you – this is a tough patch. We’re looking at a long, quiet block before anything starts to move.
We’ve got a significant gap at the start. From now right through the first week of July, there’s basically nothing doing. Kennack Sands is showing flat or tiny, weak swell for days on end. We’re talking about a stretch from July 4th right through the 13th that’s a complete write-off for any proper surfing. The water is currently about 63°, which is a touch warmer than normal for this time of year, but with no waves, that’s small comfort.
The first real sign of life doesn't show up until Sunday, July 19th. Even then, it’s not a standout, but it’s the only option on the table.
Kennack Sands
Come Sunday morning the 19th, we finally see some energy build. The combined swell energy climbs to (173) by morning, with a chest-high sort of 4ft coming from the East. The period is 8 seconds, so it’s a bit of wind swell, nothing too special. The wind is cross-off from the West, which is a big positive for keeping the faces clean.
Then by Sunday afternoon, it gets a bit more interesting. The swell pumps up to a solid 7ft from the SSW, and the combined energy jumps right up to (586). That’s a lot of juice. The period is still 8 seconds, so it’s powerful but a bit lumpy. However, the wind holds as a cross-off from the West, keeping things clean. That swell height is getting into the big territory – over 5ft, so it’ll be pushing it for beginners, and at 7ft, it’s really one for the experienced crew. Given the size and the wind being good, it’s the best looking slot of the whole run, but it’s a long way off and the long-range call is less certain.
Honestly, for the next two weeks, it’s a waiting game. This one afternoon on the 19th is all we’ve got to aim for.
Stay patient,
Rusty.
