The Lowdown
Alright, let’s talk about Kennack Sands. I’ve got to be straight with you – for the next 16 days, this spot is basically a ghost town for surf. The overall pattern is flat, flat, and more flat. The guidance shows no real swell energy coming in, and the combined energy numbers are all tiny, with most readings at 0 or in single digits. So we’re looking at a long dry spell with no real waves to get excited about. The first few days are all zeros, and that flatness stretches all the way through, with only a few tiny pulses that barely register. It’s a tough stretch for any surfer.
The first real chance of something rideable pops up on Monday, 3rd of August, in the afternoon. You’ll see a little 3ft swell start to trickle in from the south, but with a period of just 4 seconds, that’s super short-period, windswell-type stuff. It’s going to be weak and messy. The combined energy? Only 38 – that’s weak. Not exactly firing. The wind is a light breeze from the north, so it’ll be clean, but the wave quality is labelled as poor. It’s just not enough to get the heart pumping.
After that, the rest of the window is basically the same story. A few days later, around Thursday, 6th of August, there’s a tiny 1ft bump from the east, again with a short period, and the energy sits at 6. Clean wind conditions, but the size and period are just not there. It’s a beach break here, so it’s a sheltered spot, but with no real swell, you’re better off doing something else.
The water temperature is sitting at 68°, which is a massive 6° warmer than normal for this time of year. That’s very unusual – you’re swimming in bathwater, not typical surf conditions.
For a beginner, this spot is rated as inconsistent, and it’s certainly living up to that. The break is sheltered, so it needs a specific swell direction to work, and that’s just not happening. If you’re a kite surfer, the wind is going to be more interesting than the waves, honestly. The stronger breezes and cross-offshore winds will be better for kiting than for paddling into anything worth riding.
So, bottom line: there’s no standout surf on offer here. It’s a long blank run. The forecasts can change, but right now, don’t hold your breath.
