The Lowdown
Right, let’s break it down in feet and miles per hour.
First off, straight up: this is a grim outlook for Kennack Sands over the next 16 days. There isn’t a single session in the whole run that’s worth paddling out for. Not one. We’re staring at 16 days of flat to tiny, mostly blown-out nothing. That big 16-day window starts wide open with a hole where the surf should be.
Sunday 30th August kicks off with a weak, short-period 4ft SSW swell, but it’s got a 19 mph cross-shore wind tearing it up and a risk of thunderstorms. The combined energy is a weak 102 – that tells you it’s limp and messy. Poor surf all round. That afternoon’s even puffier with 22 mph cross-off wind. Not a single decent wave in sight.
Monday 31st August – swell drops to zero. Clean sky, but no surf. Tuesday 1st September is a joke: a 0.3ft S swell with an 18-second period – that long period would be great if there was any height, but there’s nothing. Combined energy of 6. You’d be bobbing on a lake.
That pattern sticks hard. Wednesday 2nd September: 0.7ft SSW, 16 seconds, 25 energy, and 22 mph cross-shore wind making a lumpy chop. Thursday 3rd September: 1ft SSW, 15 seconds, 45 energy. Still nothing. Friday 4th: 0.7ft, 25 mph winds. Saturday 5th: 0.7ft, 12 mph offshore, but still flat.
We roll into the second week and it gets even quieter. From Sunday 6th September all the way through to Monday 14th September, every morning and afternoon is either completely flat or has a tiny 0.3ft spike with almost no energy. Combined energy values are in single digits or the low 20s – that’s basically zero. The best you see is a 4ft on Saturday 12th September afternoon, but that’s a 5-second windswell from the SW with 83 energy and onshore wind. That’s a messy, short-period bump that’s more for a kite than a paddle board. It will be choppy and horrible.
There’s no standout. No best day. Nothing. The whole 16-day forecast is a blank run for Kennack Sands. It’s a sheltered spot that needs a proper SSW swell with clean wind to work, and we just aren’t getting either. This is the kind of run that’s normal for a sheltered beach here – it can go quiet for long stretches.
Stay patient. Forecasts change. That’s all I’ve got.

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.
