The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Kennack Sands over the next couple of weeks. Honestly, it's a pretty quiet stretch for this sheltered little spot. We're used to it needing a very specific window to fire, and most of this run looks like it's going to be a whole lot of nothing for paddling. The water temp is sitting about average for this time of year, so no drama there, just your standard autumn chill.
The first real flicker of life doesn't show up until Thursday the 10th of September. Through the morning we've got a weak little 0.7m SSW windswell with a messy 4-second period, but the wind is offshore out of the NW, so it’ll at least look clean. The combined energy is only 17 – barely a whisper. Then the afternoon throws a curveball: a 2.2m S swell rolls in with moderate energy (389), but the wave comment spells it out — poor surf conditions. That's a big, short-period wall of water, probably a washing machine, and well over the 1.5m mark, so not one for the beginners.
Then we get our one and only standout, and it’s a long way out. On Tuesday the 15th of September, the afternoon session is looking like the best of a bad bunch. We’ve got a 1.8m E swell, period of 6 seconds, and glassy conditions with a light SSW breeze. That’s a big positive – glassy! The combined energy is 255, so there's some moderate push in the water. With a 1.8m swell, it’s a little much for beginners, but for the rest of us, if the banks are right, it could be fun. Just keep in mind that E swell isn't its optimum from the SSW, so the shape might be a little odd at this beach break.
Other than that, there’s a brief window on Friday the 11th of September with a 1.1m SSW groundswell (128 energy) and glassy conditions in the morning, but it’s a small one and the crowds are possible there.
So, the bottom line is the surf isn't much to write home about until the second week. We've got a long gap of flat or poor conditions until the 10th, and then a few very average days before that Tuesday afternoon window on the 15th. For a spot that’s rated as inconsistent, a long quiet patch like this is pretty normal. Hang tight, or look for a sheltered reef if you’re desperate.
Rusty.

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.
