The Lowdown
Alright, let's get this straight. I'm taking a look at the current outlook for Kennack Sands, and I gotta be honest with you – it's a bit of a tough stretch. The forecast is showing a long gap with no real surf to get excited about.
For the first few days, from Friday 17th July to Monday 27th July, it's pretty much a flat spell. The swell is tiny, mostly under 3ft, and the wind is often cross-shore or onshore, which isn't doing us any favours. The combined wave energy is weak, barely cracking double digits to start. It's a frustrating wait for any kind of wave.
The standout period, if you can call it that, arrives on the morning of Thursday 30th July. We'll see a small east-northeast swell pushing about 2ft to 3ft, with a combined energy of 19 to 33. The wind is forecast to be offshore from the northwest, so the conditions will be clean. The swell direction is east, which is a long way from the optimum south-southwest for this sheltered spot, so the waves will likely be small and weak. The water temperature is about average for the time of year, nothing unusual.
Honestly, this is a quiet period for Kennack Sands. It's an inconsistent break anyway, so a blank run like this isn't totally out of the ordinary. Keep an eye on the forecasts, but don't hold your breath for anything epic.

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.
