The Lowdown
Alright, Rusty here again, switching to feet and Fahrenheit for you lot. Let’s break down Kennack Sands over the next sixteen days. Straight up – the finder’s showing zero good surf options. Nothing worth a paddle.
This is a long, flat stretch. Kennack is a sheltered spot, so it’s picky. Across the whole period, we’re looking at tiny waves or flatness. The first week is mostly scraps under 0.7ft, with combined swell energy in the teens or lower (20), and plenty of days with zero energy. Winds are often strong out of the west-northwest, which is offshore here, but there’s no swell for it to groom.
Water temp is around 64°, which is a touch warmer than normal for this time of year – about 2°F above average. Nothing crazy.
Into the second week, there’s a little bump around September 14th with easterly energy near 2ft and combined energy just over 20, but the period is short – around 5 seconds. Weak stuff. By September 18th and 19th, the swell builds a bit, with the 19th seeing 6ft from the east and combined energy hitting 255. That’s moderate energy, but the period is only 6 seconds and the wind is onshore from the southeast. That’s gonna be messy. For that setup, and given it’s a beach break, it might be more interesting for kite surfing than paddle surfing.
So, for the full 16-day window, there’s nothing I can recommend. A blank run like this is fairly normal for Kennack – it can go quiet, but it doesn’t usually stay flat for long. Forecasts can change.
Rusty.

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.
