The Lowdown
Right then, let’s talk about the next couple of weeks here at Kennack Sands. To be straight with you, it’s a pretty bleak run. There’s no real swell to speak of for the first few days, and what little does show up is getting battered by the wind. The water temperature is sitting at 67°F right now, which is a solid 6°F warmer than usual for this time of year – that’s a very unusual anomaly, so you’ll be feeling that difference.
The first sniff of anything might be on Thursday the 16th of July. We’ve got a tiny 4ft swell from the east, but the wind goes glassy by the afternoon. The combined energy is weak (86), and the period is a short 6 seconds, so it’s not going to be a world-beater. It’s surfable, but it’s very ordinary. Still, a glassy window is a glassy window, and for a beginner or longboarder, you might get a few fun, wobbley ones.
After that, it’s a long, dry gap. The swell just fades away completely. From Friday the 17th right through to the end of the forecast on the 28th of July, the numbers are flat. We’re talking swell heights of 1ft or less, or simply no swell at all. The combined energy drops to zero for many days. There’s a couple of days with a long period groundswell signal from the south (19 seconds on the 19th, 16 seconds on the 21st), but the height is so tiny – 0.3ft – that it’s just a ripple. It’s a real blank run.
So, what’s the best on offer? Honestly, it’s that Thursday afternoon. There’s no standout. The rest of the time, the wind is mostly cross-on or onshore, often strong, and the swell is missing. This setup looks more interesting for kite surfing than paddle surfing, if you’re into that. For a surfer, you’re looking at a long wait. The forecasts can change, but for now, the boards are staying in the car.

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.
