The Lowdown
Alright, Rusty here again. Let’s call it like it is: Kennack Sands is looking bleak for the next sixteen days. The swell is on life support, and the wind is a pain in the neck. If you’re keen, you’ll be twiddling your thumbs for a while.
The first week is a total bust. The waves are tiny, the wind is blowing onshore or cross-onshore, and the water is running a bit warmer than usual for late August at 65.8°. You’ll see a brief spike in energy on Monday the 24th, with a combined energy of 384, but that’s a 6.6ft east swell with a short period of 7 seconds, getting hammered by 25 mph east winds. That’s a mess, not a surf session. It’s more of a kiteboarding setup than a paddleboarding one. The rest of that week is just poor conditions and zero scores.
There’s a big, dry gap from the 22nd all the way to the 1st of September. After that, we get a few tiny pulses of very long-period groundswell from the SSW, with periods of 15 to 18 seconds, but the heights are pathetic—0.7ft to 1.0ft. The energy is weak (50 or less), and the wind is still cross or onshore. Your best shot is on the 6th of September, when a 0.3ft, 13-second S swell meets a clean 19 mph cross-offshore west wind. But that’s nothing for anyone but the most dedicated. There’s no standout here. Just wait it out, and hope things change.

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.

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.
