The Lowdown
Alright, this is Rusty, and I've got a straight-up honest look at what's coming for Kennack Sands over the next couple of weeks. Let's be real with it.
Right now, the surf scene is pretty much flat. We’re looking at a big gap of nothing much for several days. The water is sitting at 64°, which feels a touch warmer than normal for this time of year, so that’s a nice bonus for a paddle, but you won't be catching any waves.
The first few days are a total write-off. Thursday the 3rd and Friday the 4th are barely registering a bump, with tiny 0.7ft to 1.0ft swells and messy cross-off winds. The wave energy is pitiful, in the 20s (22 to 47). Not worth getting wet for. Saturday the 5th is glassy in the morning which is beautiful to look at, but it’s still a lake at 0.7ft. Sunday the 6th sees a little bump to 3ft from the SE, but the period is a dreadful 4 seconds with onshore winds, so it’s just junk.
Then we hit a dead zone. From Monday the 7th right through to Thursday morning the 10th, there’s essentially zero swell – the combined energy is sitting at 0 for most of that. It’s like the ocean took a holiday. You’d be better off cleaning the wax off your board.
Things try to flicker back to life on Thursday afternoon the 10th, with a 3ft SSW swell but a short 6-second period. The energy jumps to 68, which is still weak, and the wind is cross-off. It’s a tiny, weak closeout at best. Friday the 11th is a total blowout with strong offshore NW winds at 19 mph, but no swell to work with. The pattern of tiny, weak pulses continues right through to the end of the second week, with nothing cracking the 3ft mark.
If you’re a kitesurfer, the setups on the 6th, 13th, and 14th with onshore or cross-shore wind and a bit of chop might look more interesting than anything a paddler would want. For the rest of us, this is a long, quiet stretch. Kennack is an inconsistent spot at the best of times, and this run is a prime example of a blank period. The forecasts can change, but for now, it’s a firm “stay on the beach” outlook.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennack Sands may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
