The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook is a tough one. We’ve got a 16-day window ahead, but for the first week and a half, it’s flat. I’m not talkin’ small, I’m talkin’ nothing. That calm starts now and runs all the way through to the end of July, with hardly a ripple to get excited about. You’ll be lookin’ at a solid 11 days of quiet water before anything even hints at a ride.
The only break on the radar for this whole region is Kennack Sands. It’s a sheltered spot, so it needs a very specific angle to light up, and that just isn’t happenin’ for a long while. The water temp is sittin’ at 68°, which is a massive 6° warmer than usual for this time of year – that’s very unusual, almost like bathwater. You could swim in a t-shirt, but you won’t be surfing.
The first real glimmer comes on Sunday, August 2nd in the afternoon. We finally see a pulse of energy: a 4ft east swell, with a moderate offshore wind from the NNW. The combined energy hits 214 (moderate), which is the only real show in town. The period is only 7 seconds though, so it’s a short-period windswell – not gonna win any beauty contests, but it’s the only wave in the house. Kennack is a beach break, and with that short period, the waves will be a bit soft and crumbly. It’s surfable, but very ordinary. Beginners might find the 4ft a little punchy if it closes out, but it’s not a washing machine.
After that little blip, the energy drops right back off. The first couple days of August look like they’ll try to send a bit more east swell, but it’s tiny and inconsistent. By August 4th and 5th, the wind swings onshore and freshens up, making a mess of things. Honestly, with the lack of surf and the onshore wind, this setup might be more interesting for a kite surfer than a paddle surfer during that mid-week stretch.
So the bottom line is: if you’re desperate, mark your calendar for the afternoon of Sunday, August 2nd. It’s the only chance for a wave, and it’s not a classic. The rest of the window is a write-off. This is one of those stretches where the sea just needs a proper kick-start. Keep an eye on the charts, but for now, I’d wax the longboard and leave it in the car just in case.
Rusty.
