The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' for Kennack Sands over the next couple of weeks. I gotta be straight with you, it's a bit of a tough stretch for paddle surfing. This spot is a sheltered one, so it needs just the right angle of swell to get going, and we're mostly looking at small, weak stuff. The water is sitting at a balmy 67°, which feels much warmer than normal for this time of year—that's a nice little bonus if you're just having a float.

We kick things off on Sunday the 16th with tiny 0.3ft south swell. The energy is a measly little 3 (combined swell energy), and while the wind is offshore on Sunday afternoon, there's just nothing to ride. This limp spell stretches right through the whole week. We see a tiny blip on Tuesday the 18th morning, with a 0.7ft SSW swell and a bit more energy at 27, but it's still weak and the wind is cross-off. It's the same story all the way until the 22nd of August. That's over a week of flat or near-flat conditions—a real dry spell for a wave that is already inconsistent.

Now, things get a bit more interesting but not better for surfing. On Sunday the 23rd, we see a bump in swell height, up to 5ft to 7ft from the east. The combined energy jumps up to 187 and then 395, which is moderate, but it's a short-period wind swell at just 6 to 7 seconds. That makes for bumpy, disorganised waves. The wind is blowing strong cross-onshore from the east, so it's going to be lumpy and messy. Honestly, with that sort of howling wind and half-decent swell, this setup looks more interesting for kite surfing than paddle surfing.

The next few days get a bit bigger but even messier. On the 24th, we're looking at 6ft to 7ft of east swell with a strong, messy cross-onshore wind. The combined energy hits 429, which is solid, but the quality will be poor. On the 25th, we get a 6ft east swell and the wind turns cross-shore, still fresh and lumpy. By the 25th afternoon, the wind backs off and goes cross-off, dropping the swell to 3ft, but it's a short, weak pulse.

After that, the swell dies right back down. We get a few glassy mornings on the 27th and 28th, but with zero to 0.7ft of swell, you're just looking at a flat, pretty ocean. There's a glassy window on the 27th Thursday morning, but again, no waves.

So, the honest truth lads, there are no standouts in this 16-day window. It's a long run of poor to unsurfable conditions. This blank run is a bit much for the area, but it can happen when a sheltered spot like Kennack is waiting for the right swell. Keep an eye on the charts, things can change, but for now, I'd leave the board at home.

Rusty.

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.

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.
