The Lowdown
Alright folks, Rusty here. Let's be straight with you: the next sixteen days are looking like a real struggle for a wave around here. We've got a long, dry spell ahead with very little to get excited about.
The first faint sign of anything rideable doesn't show up until the afternoon of Friday the 31st of July. Even then, it's a tiny 0.3ft south swell with a long 12-second period, but it's blown out by a 15 mph offshore wind. That's not surf, that's just a bumpy, white-capped sea. The water is a balmy 67°, which is much warmer than normal for this time of year, but that's small comfort when there's no wave to paddle into.
We then go through a long stretch of flat, poor conditions right through the first week of August. Saturday the 1st is glassy but flat. Sunday the 2nd sees a tiny, short-period 2ft east windswell, but with onshore winds that chop it to pieces. Monday and Tuesday are flat and messy. Wednesday the 5th and Thursday the 6th stay flat. There's a little 0.7ft south groundswell on the afternoon of the 6th, but it's just a whisper with only 14 units of energy. Nothing to ride.
The second week doesn't offer much hope either. Friday the 7th of August brings a 2ft east windswell, but it's sloppy. Saturday the 8th has a glassy morning, but the swell is a pathetic 0.7ft. The afternoon picks up a bit of offshore wind and a 2ft east swell, but the period is a short 6 seconds. It's a clean but gutless little wave. The rest of the week into the 14th is a mix of flat days and tiny, weak windswell with cross and cross-offshore winds. The best looking day is Friday the 14th of August, with a 4ft east swell and a 6-second period, but the wind is a strong cross-offshore 18 mph. It's got some energy (97 units) but it's still a weak, chop-prone windswell that will be difficult to enjoy. Even then, the guidance says "poor surf conditions."
Given the break is a sheltered spot, it just isn't catching any decent energy. The consistent lack of quality, the small size, and the wrong winds mean there's genuinely nothing to recommend. For a few days in the second week, the setup might look more interesting for a kite surfer than a paddle surfer, but for us wave hunters, it's a wipeout.
Keep the quiver in the car, and keep an eye on the charts. It tends not to stay this poor forever.
Rusty.

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.
