The Lowdown
Right, surfers, Rusty here. Let's be straight about it – the outlook for this neck of the woods over the next sixteen days is pretty damned quiet. We're looking at a whole lot of flat spells and tiny, weak leftovers. Don't get your hopes up for any standouts, because there aren't any.
The first bit of surf we see shows up on Thursday the 6th of August at Kennack Sands, but it’s not much to write home about. We're talking a mere 0.6ft dribble from the SSW with a short, weak 6-second period and a combined energy of just 3 – that's barely a ripple. The afternoon has a cross-offshore wind (W 16 mph) but the swell is so weak it's essentially flat.
Friday the 7th of August starts off glassy with a light morning breeze from the SW, but there's zero swell. The afternoon is similar – flat with a cross-offshore breeze.
We get a tiny pulse on Saturday the 8th of August afternoon – 0.3ft from the south with a 13-second period and combined energy of 5. It's a long-period groundswell, but so small it won't break properly. The wind swings onshore from the SE, which isn't doing it any favours.
Sunday the 9th and Monday the 10th of August offer clean, offshore conditions, but again, the swell is virtually nonexistent. There's 0.3ft on Monday morning with that same long-period southern groundswell, but it's just a whisper.
Things get a tiny bit more interesting around Wednesday the 12th of August. We see 2ft of easterly swell with a 7-second period and a combined energy of 37 to 43. The wind is cross-offshore from the WSW. It's small, weak windswell, and frankly, it's still poor surf.
From there, it’s back to tiny, inconsistent pulses. A few 0.3ft southerly groundswell pulses show up on the 14th and 15th of August, and later on the 16th and 17th of August we get a 0.3ft to 0.6ft southern groundswell with a very long period of 16 to 19 seconds. The combined energy stays weak, between 3 and 24. Even with offshore or clean winds, the swell is just too small.
The last few days of the outlook, the 18th, 19th, and 20th of August, actually see some of the strongest winds, with strong breezes from the WNW hitting 25 mph, creating clean but howling offshore conditions. The swell is still only 0.3ft to 0.6ft. At Kennack Sands, a sheltered spot, the setup looks more interesting for kite surfing than paddle surfing if you're into that, but for a surfboard, it's a hard pass.
Water temps at Kennack Sands are sitting at a very unusual 67°, which is much warmer than normal for this time of year – a nice surprise for the skin, but there's just no wave to enjoy it.
The bottom line: The entire 16-day forecast is a write-off for surf at Kennack Sands. It’s a rare, inconsistent break at the best of times, and these forecasts confirm a long, blank run. Don't bother waxing up just yet.

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.
Kennack Sands is 9 km (6 miles) from The Lizard. If you plan a holiday in South Cornwall, look for hotels and other accommodation in The Lizard. The Lizard has rooms for a wide range of budgets as well as car hire and transport links.
