The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Right off the bat, I’ve got to be straight with you – this is a tough stretch. The whole 16-day window looks pretty flat for Kennack Sands. We’re talking about a prolonged run of tiny, weak energy with next to nothing worth paddling out for. The first real chance at a wave comes right at the start, but even then, it’s a struggle.
Friday 31st July kicks things off with a sliver of swell – a tiny 0.3ft from the south, with a long 12 second period. The combined energy is a measly 3. That’s barely a ripple. The morning has a gentle offshore breeze from the NNW at 9 mph, so the water might look clean, but there’s just no power. The afternoon gets a bit windier, 16 mph from the NW, still offshore, but still nothing to ride. The water temperature is sitting at 67°, which is a whopping 5° warmer than usual for this time of year – that’s very unusual, but it won’t help the waves.
We then hit a long, dead gap. From Saturday 1st August right through to Wednesday 5th August, there’s hardly any swell. You get a few days with 0.0 swell energy, then a tiny 1ft from the east on Sunday 2nd with a pathetic 3 second period – that’s just wind chop, and it’s coming with an onshore wind. Not surfable. The energy stays in the single digits or low tens. It’s a real dry spell.
On Wednesday 5th August, we get a slight pulse: 3ft from the southwest, period of 6 seconds, and the combined energy creeps up to 46. The wind is clean and cross-offshore from the WSW at 9 mph. It’s the best of a bad bunch, but 3ft with a short period is still pretty weak. For a beginner spot that’s inconsistent, this is about as good as it gets in this window, but it’s nothing to write home about.
The rest of the week and into the second week is more of the same. A few tiny 0.3ft to 0.7ft pulses from the south, with long periods but no size. The combined energy stays below 20. There’s a glassy morning on Saturday 8th August with a 0.3ft, 13 second south swell, but it’s a ghost wave. The wind is dead calm – glassy, but the swell is just too small to do anything.
From Sunday 9th August onwards, it’s mostly flat again. A few 2ft east swells with 4 second periods show up on Wednesday 12th August, but the energy is still only 18. The wind is cross-offshore, but the waves are windswell and weak. By Friday 14th August, the wind picks up to 22 mph from the SW, making it lumpy and cross-shore – not a good look.
The very last day, Saturday 15th August, has a strong offshore wind from the NW at 25 mph, which cleans it up, but there’s no swell to speak of. A 0.3ft south swell with a 12 second period and an energy of 3. It’s hard to paddle into even if there was a wave.
Honestly, this is a blank run. Kennack Sands is a sheltered, inconsistent spot, so a run this flat is not unusual. If you’re desperate for a paddle, that Wednesday 5th August morning is the only time you might get a tiny, clean crumble, but don’t expect much. The energy is just too low across the board.
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.
