The Lowdown
Alright folks, Rusty here. Let's be straight-up: we're looking at Kennack Sands for the next 16 days, and it's a tough watch. This is a sheltered spot, so it doesn't grab much swell at the best of times, and right now we're in a proper flat spell with only tiny scraps of energy. The water's sitting at about 65°, which is a touch warmer than usual for this time of year – a little bonus for the soul if not the surf.
We're kicking off in a real flat spot. From Thursday the 10th right through the weekend and into the middle of the following week, there's simply nothing doing. No surf to speak of. A long stretch of calm, clean conditions, but zero rideable waves.
Now, around Tuesday the 15th, we get a little tickle. A pulse of 2 ft from the SSW shows up in the morning, with a short period of just 5 seconds. That's barely enough to wrap your head around, and the combined energy is a measly 21. The wind is offshore from the WNW at 30 km/h, which will keep it glassy clean, but this is strictly for the keenest longboarder who wants a knee-high wobble. It's the best of a bad bunch, but only just.
After that, it's back to the doldrums. Tiny scraps from the south keep washing through for the rest of the week and into the next, but with a mix of cross and cross-onshore winds. No consistency, no power. It's one of those stretches where the forecast can change, but as it sits, there's nothing worth paddling out for. Honestly, with these tiny, short-period waves and the wind directions, this setup looks more interesting for a kite than a surfboard for most of the run.
Signing off, Rusty.

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.
