The Lowdown
Alright folks, Rusty here. Let's look at what Kennack Sands has cooking.
Honestly, it’s a slow start. Nothing really doing for nearly the first five days. You can forget the first half of the week. Winds are messy, and when there's some height, like a 8ft swell on Monday afternoon, it's just a wind-blown mess with a combined swell energy of 640 (moderate). No thanks.
Our one real chance comes on Friday morning, August 28th. That's the day. We're looking at a 7ft swell out of the SSW, with a period of 9 seconds. The combined energy hits 764 (moderate to strong). But the kicker is the wind: a light 6 mph from the WNW, clean and cross-offshore. It’s going to be clean. This might be a bit much for beginners, but for everyone else, it’s the session of the window. The report says "expect good surf conditions," and I agree.
Friday afternoon cleans up even more, going glassy as the swell drops to 5ft. Easy paddling.
After that, it’s a fade out. A tiny 3ft bump on the 30th, but the wind is wrong. Then we hit a flat spell of scraps under 1ft all the way through to September 5th. There’s a 16-second groundswell wave on September 2nd, but it's only pushing 0.7ft. That’s a tease, not a wave.
One day. Friday the 28th. That's your window.

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.
