The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Kennack Sands over the next couple of weeks.
Honestly, it’s a pretty grim run for Kennack Sands. The whole 16-day window is essentially a write-off for any decent surf. There’s no swell to speak of, and what little does show up is tiny and weak. You’re looking at a long gap of poor conditions from the start right through to the end. The first glimmer of anything comes on the 28th of August, but it’s barely worth mentioning.
Friday the 28th of August morning offers the best of a bad lot, and that’s not saying much. You’ve got a tiny 2 ft swell from the SSW, but it’s short-period windswell at 6 seconds, so no real punch. The water temp is 65°, which is a touch warmer than normal for this time of year. The wind is cross-off from the WSW at 16 mph, which will keep things clean, but the combined energy is only 22 – that’s weak. It’s really just a knee-high dribble. The afternoon gets worse with the wind picking up to 22 mph.
From there, it’s all downhill. Most days show zero swell or waves too small to ride, and the wind is either cross, cross-off, or howling onshore. A few mornings, like the 31st of August and 1st of September, have clean conditions with offshore or light winds, but the swell is basically flat – 0.3 ft or 0.7 ft. The 1st of September morning has a long-period 18-second groundswell from the south, but it’s only 0.3 ft high and the energy is just 6 – that’s barely a ripple. It’d be a glassy pond, not a surf.
The second week is more of the same. Tiny pulses of swell from the SSW, all under 2 ft, with clean but weak conditions. The 8th of September has some offshore wind and a 0.3 ft south swell at 11 seconds, but the combined energy is a pathetic 2. By the 10th of September, the swell direction swings to the ENE and E, but the period drops to 4 or 5 seconds and the heights are tiny. The last few days on the 11th and 12th of September are just windy and messy, with strong cross-shore winds and no surf.
Bottom line: don’t bother paddling out. The setup here is so weak that if you’re after any kind of thrill, this is more of a kite-surfing kind of spot with those winds, not a paddle-surfing one. Kennack Sands is an inconsistent, sheltered beginner spot at the best of times, and this forecast is a complete blank run. It happens. Forecasts can change, but right now there is nothing worth chasing.

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.
