The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for Kennack Sands over the next couple of weeks.

Straight up, I gotta be honest with you – it's looking pretty bleak. We've got a massive 16-day window here, and there's virtually nothing to get excited about. The whole forecast period is a long, flat spell. From now right through to the end of the 16 days, the wave energy is either zero or a measly little number in brackets (5), (8), (4) – it's all weak, pathetic energy. The swell height barely registers, just a tiny 0.3 ft here and there. There are no standouts, no hidden gems, nothing. For a spot like Kennack Sands, which is already inconsistent, this kind of blank run isn't totally out of the ordinary, but it's still a tough one to swallow.

If you're desperate for a paddle, the only tiny blip comes on the 18th of September. There's a bit of a long-period groundswell from the south, with a 0.3 ft swell and a period of 18 seconds. At a sheltered spot like Kennack, that long period might help it wrap in slightly better than nothing, but honestly, it's still tiny. The wind is offshore from the WNW, which is clean, but it's a fresh breeze at 22 mph, so it'll be a battle to stay out. The energy is still weak (12). There's nothing here for the 15th of September either, despite the glassy conditions – the swell is just too small.

So, in short, the surf is poor. The water temperature is about average for the time of year, so no surprises there. Keep the board in the car and the wax in the wrapper. This one's a write-off.

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.
