The Lowdown

Alright folks, Rusty here. Let's be honest, this is a tough one. The data shows we're in for a proper flat spell around Kennack Sands. The entire 16-day window is looking pretty grim. The first surf of any kind is pretty much a no-show, and the whole period is a lineup of tiny, weak pulses and poor conditions.

Right now, we're looking at a long stretch of nothing. From Tuesday, August 4th, all the way through to the middle of the month, the swell is almost non-existent. The best we get is a tiny 0.3ft south swell with a long 15-second period, but it's arriving with a 16 mph cross-shore wind, making it messy and poor. The water is sitting at 66°, which is a touch warmer than usual for this time of year, but that's about the only positive. The combined energy is a measly 4, so you're basically looking at a lake.

A few days in, around August 7th, we get a glassy morning, but with no swell at all, it's just a flat, pretty morning. The wind turns offshore on the 6th and 8th, but again, the swell is absent or too small to do anything with.

Around August 11th, we get a little bump of 3ft from the east, but the period is a short 4 seconds and the wind is a fresh 19 mph cross-onshore. That's lumpy, choppy, and not worth a paddle. The energy is still only 24 (weak).

The rest of the outlook is more of the same. Tiny 0.3ft pulses from the south with long periods, but the wind is often cross-shore. Even when the wind is offshore, like on the 13th and 14th, the swell is just too small to do anything with. The combined energy barely cracks single digits.

To be blunt, there are no standout days. No good options. For Kennack Sands, this is a typical blank run. It’s a sheltered spot, and when the swell isn't hitting, it just doesn't work. Don't waste your time checking the cams for the next couple of weeks. Forecasts can change, but right now, it's a big fat zero.

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. 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.
