The Lowdown
Alright, I’ll talk straight about Kennack Sands. It’s going to be a rough stretch. This break is sheltered and inconsistent even when conditions are good, and the next couple of weeks are pretty barren. Most of the time the wind is blowing across or onshore, and there’s just no real swell coming together. There’s a big gap before anything even looks worth paddling out for.
The first few days, starting Monday the 24th of August, are a total mess. Strong easterly winds, messy onshore chop, and wave heights that have size but no shape. That 2.2m on Monday afternoon is from the east with a short, weak period of 7 seconds and combined energy of 518 (moderate) – but it’s all blown out. This kind of wind and beach setup is better for kite surfing than for a paddle surfer.
The only time it cleans up is Friday the 28th morning. Clean conditions, a light WNW offshore breeze, but almost no swell – just 0.1m from the south with a 12 second period. Barely a ripple. That pattern keeps going right through: clean, offshore or cross-off winds, but the swell stays tiny. A 0.2m here, a 0.3m there, all with long periods from the south-southwest.
Your best chance might be Saturday the 29th afternoon – a 1.1m SSW swell at 7 seconds, combined energy of 132 (weak to moderate), and clean conditions. Still, it’s a short-period, weak swell at an inconsistent, sheltered beginner spot. Not something to get fired up about. The water is around 18°C, a touch warmer than usual for this time of year.
From the end of August all the way to the 8th of September, it’s flat. Clean skies, offshore breezes, but zero swell. Over a week of nothing. The northwesterlies blow hard but bring no waves. Long period south swells show up but they’re tiny and break too straight for a beach break like this.
Bottom line: there’s no good surf in this 16-day window. Kennack Sands is inconsistent, and this kind of dry spell is normal around here. The forecast can always change, but for now, I’d leave the boards at home.

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.
