Table - best surf conditions forecast for Kennack Sands over the next 16 days.
Alright, let’s have a look at the numbers for Kennack Sands. It’s a grim 16 days, I won’t lie. The first week and a half is a total blank with no energy in the water. The combined swell energy is zero for days on end.
The first flicker of life comes on the morning of July 15th. We’ve got a 2.2m swell from the east, with a short 7 second period, and a combined energy of 554. The wind is a light offshore from the WNW, so it’ll be clean. It’s something, but not much.
The morning of July 16th is the best of a bad bunch. The swell is 1.6m from the east, with an 8-second period and a combined energy of 312. The wind is a gentle offshore from the WNW, so it’ll be clean. It’s surfable, but it’s a very ordinary session. The water is 63°, which is a touch warmer than normal for this time of year.
Other than that, it’s a mess. The wind is mostly cross-on, the swell is short and weak, and the sea state is choppy or blown out. For an inconsistent, sheltered spot, this is a real dry spell. There’s a long gap of more than a week before the 15th. Don’t hold your breath.

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.
