The Lowdown
Right then, let’s have a look at what’s on offer for the next sixteen days. I’ll be straight with you, mate—it’s a tough stretch. The whole period is a bit of a write-off, to be honest. There’s no real swell to speak of, and the models are showing a long, dry gap. You’re looking at a run of over a week with absolutely nothing worth paddling out for.
We start off on Monday, the 7th of September, at Kennack Sands. The water’s a touch warmer than normal for the time of year at 64°, but that’s where the good news ends. The swell is a measly 0.3 ft from the south with a 12-second period, giving a combined swell energy of just 3. That’s barely a ripple. The wind is offshore from the WNW at 12 mph, so conditions are clean, but there’s simply no wave to surf. It’s a flat, clean pond.
Tuesday the 8th offers a tiny bump in the afternoon: 1 ft from the SSW with a short 6-second period. Combined swell energy is still pathetic at 16. The fresh offshore wind from the NW at 22 mph will keep the surface glassy, but that swell is too weak and short-period to form any real shape. It’s not for beginners, but honestly, it’s not for anyone.
The rest of the first week and into the second week is a total blank. From Wednesday the 9th all the way through to the 21st of September, the guidance keeps spitting out “poor surf conditions.” There are scattered days with tiny 0.3 ft or 0.7 ft pulses, but the combined energy is almost always in the single digits or low teens—weak and useless. The wind is often offshore or clean, but you can’t surf wind.
The one tiny flicker comes on Sunday the 20th of September, with an afternoon pulse of 2 ft from the east at a 6-second period. The combined energy jumps to 17, but that’s still very weak. It’s accompanied by a risk of thunderstorms and a fresh cross-offshore breeze at 19 mph. The setup looks more interesting for kite surfing than paddle surfing.
Then into the last few days, Monday the 21st has a little 1.0 ft from the ENE with fresh offshore winds, but again, the energy is only 7. The swell direction is east, which is not the optimum SSW direction for this sheltered spot. Absolutely nothing stands out as a recommendation.
So, I hate to say it, but there are no good surf options in this 16-day window. For an area like this, when the swell is this lacking and the spots are inconsistent, it’s normal to have a blank run. Forecasts can change, so don’t lose all hope, but for now, keep the board in the van.

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.
