The Lowdown
Alright, this is a tough one for the Lizard. I'm looking at the whole 16-day window, and I gotta be straight with you – it's a proper flat spell for Kennack Sands. The first few days are a write-off, with barely a ripple and poor conditions. After that, we get a long stretch of nothing but tiny, weak swells or complete flatness. The wind is mostly onshore or cross-shore, adding to the misery. Honestly, there's not a single moment in this whole forecast that I'd call a surfable wave. The water temp is about 63.9°, which is a touch warmer than usual for early September, but that's the only bright spot. We're looking at a solid 16-day gap with no real surf on offer. There's simply nothing to get excited about for a paddle surfer. The swell energy is almost always in the single digits or low teens, with the highest reading being a paltry 53 on the 11th, but that's accompanied by a short period and still poor conditions. It's a proper blank run for this sheltered spot. If you're desperate, maybe a kite could get going on one of the windier days, but for a surfboard, it's a no-go.

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.
