The Lowdown
Alright folks, it’s Rusty here. Let’s get straight into it. I’ve had a look at the latest charts and, well, I’ve got to be honest with you – it’s a tough one. We’re looking at a 16-day window that’s basically a flat spell for the whole stretch. There’s not a single decent wave to be had, so if you’re hoping for a session, you’re going to need a lot of patience and a different hobby for a while.
The only spot on the radar is Kennack Sands, and it’s a real heartbreaker. This place is a sheltered beginner spot, inconsistent at the best of times, and it’s just not firing. The whole period starts with a tiny 0.3 ft swell from the S, with a period around 11 seconds. That’s just not enough energy – the combined energy is a measly 2 (weak). The wind is a fresh offshore from the NW on Sunday the 26th of July, which would keep it clean, but with no wave height, it’s just a flat, pretty lake. It’s a real shame because the water temperature is about average for the time of year, nothing unusual there.
That sets the tone for the whole run. We go straight through the end of July and into August with nothing. There are gaps of multiple days where the energy is either zero or so tiny it’s not worth mentioning. Monday the 27th and Tuesday the 28th see a bit more wind, but it’s cross-off or onshore, and the swell is still just 0.3 ft. The combined energy rarely gets above 8 (weak). The whole setup is just a bust.
The only minor blip comes on Saturday the 1st of August. We get a 1 ft swell from the SSW with a period of just 3 seconds. That’s a short-period, weak windswell, but the wind is a glassy N at 5 mph. The combined energy is still only 3 (weak), so it’s not breaking. It’s a classic case of a clean, empty ocean.
From there, it’s a long, drawn-out flat spell. We see some strong offshore winds on the 4th and 5th of August, with a 31 mph near gale from the WSW, but the swell is still just 0.3 ft and the energy is between 5 and 8 (weak). There’s just nothing to push. The rest of the first week and the entire second week is a write-off. The swell direction is SSE, but the period is short and the height is minuscule.
If you’re a kite surfer, the strong winds from the 4th of August might look interesting, but for a paddle surfer, it’s a complete blank. This is the kind of run that’s more normal for a sheltered spot like this, but it still stings. The outlook is a no-go. Keep the board in the car, it won’t be long before things change. Forecasts can flip.
Rusty.
