The Lowdown
Right folks, Rusty here. Let’s have a look at what’s on the table for Kennack Sands.
Honestly, it’s a grim outlook. Over the entire 16-day period, there’s not a single good option. We’ve got a long stretch of nothing worth paddling out for. The first few days offer tiny, weak waves – think 0.7ft to 1ft – with a long-period SSW groundswell that just doesn’t have any push. The combined swell energy is pathetic, barely scraping 50 in the early going, which is just background noise. Even when the wind turns offshore on Friday the 4th, it’s on waves too small to bother with. There’s a gap then through the middle of the window with absolutely no swell at all for days on end.
By the time we get a little bump on Sunday the 6th, the period drops to a shocking 5 seconds. That’s windswell junk, and with a weak combined energy of 48, it’s just messy. The water temp here is 64°, which is about normal for the time of year, nothing to write home about.
Later on, around the 12th and 13th, we see a few tiny pulses (0.3ft) with a long-period (15 seconds) SSW groundswell, but again, the energy is minimal (4 to 6) and the wind is either cross-on or light offshore on waves that are knee-high at best. For a sheltered north-coast spot like Kennack Sands, the SSW swell direction is fine, but there’s just no size or power.
Plainly put: there are no surf options worth your time in this 16-day window. Kennack Sands is an inconsistent spot anyway, and this blank run is pretty normal for the area. Don’t hang your hopes on it – forecasts can change, but right now, leave the board at home. Stay tuned, and I’ll let you know if anything shifts.

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.
