The Lowdown
Right then, let’s have a look at what’s on the cards for Kennack Sands over the next couple of weeks. I’ll be straight with you, it’s not looking like a classic run. We’ve got a whole lotta nothing for the first few days, and when we do see a pulse, it’s mostly small and messy. You’re gonna have to pick your moments, and even then, it’s about managing expectations.
The water’s sitting at 66.4°F, which is a touch warmer than normal for this time of year, so that’s a small win if you’re just having a paddle.
The first proper chance of anything comes on Tuesday the 11th. The swell fills in a little from the east, with 4.6ft on the face in the afternoon. But, and it’s a big but, the wind is howling cross-onshore from the east at 22 mph, so it’s gonna be lumpy, bumpy, and a bit of a battle. The energy is moderate at 122, but it’s not going to be pretty. If you’re a glutton for punishment, you might get a few, but it’s not one for the faint-hearted.
Wednesday the 12th is a similar story, with 4.6ft of easterly swell in the morning (energy 168), but that cross-onshore breeze is still messing it up. It’s a bit of a grovel.
After that, it just fades away. The end of the week and the weekend are looking tiny, with nothing but ankle-biters. The wind goes offshore, so it will be clean, but there just isn’t any swell to push it. You’d be surfing whitewash.
We then have a long stretch of nothing, a proper lull that runs from the 13th through to the 18th. It’s just flat. If you’re desperate, you could count the ripples, but that’s about it.
Now, the long-range charts are showing a pulse of long-period southerly groundswell arriving around the 19th of August. The period is up at 15-17 seconds, which is a proper deep ocean swell, but the height is only forecast at 0.7ft. That’s tiny. The wind is light and variable, so it might be glassy, but with that little energy, it’s going to be tough to get a ride. It’s promising in theory, but it’s a long way out and the size just isn’t there. It’s more of a ‘keep an eye on it’ than a ‘get your board wet’ situation.
Kennack is a sheltered little cove, and it takes a good solid swell to get it working. This outlook is a prime example of that. We need a bigger push from the south or southwest to get any real waves wrapping in. For now, it’s a flat spell. Sometimes it just be like that, but it won’t stay poor forever.

Information about the Kennack Sands Surf forecast
The above surf forecast table for Kennack Sands provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennack Sands can be found by selecting the local surf guide option on the grey menu. Our Kennack Sands surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennack Sands) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
