The Lowdown
Alright folks, Rusty here. Let’s have a look at what Kennack Sands has got cookin’ for the next couple of weeks.
Well, I gotta be straight with you – this outlook is a tough one. We’re looking at a long, dry spell with barely a ripple for days on end. The water is a super warm 68°F, which is a whopping 6°F warmer than usual for this time of year, so it feels like a bath, but there’s just no energy to surf on.
For the first two weeks, it’s a total bust. From Thursday the 23rd of July all the way through to Tuesday the 4th of August, the scores are a flat zero. We’re talking about tiny scraps of southerly windswell, periods under 14 seconds, and combined wave energy values that barely reach single digits (like 4 or 8). The wind is all over the place – sometimes offshore, sometimes cross – but it doesn’t matter because there’s nothing to ride. It’s a brutal stretch of “poor surf conditions” day after day.
Then, finally, we get a little flicker of life on Wednesday the 5th of August. The morning shows a little 4ft east swell, but the period is a super short 5 seconds, so it’s gonna be weak and bumpy. The combined energy is still only 92, so it’s weak. The wind is a gentle offshore from the NW, so it’ll be clean, but the waves themselves will be pretty ordinary. The afternoon picks up a bit to 5ft from the ESE, with a slightly better 6-second period, pushing the energy to 154 (moderate). But it’s cross-offshore wind, so it’s not going to be perfect.
Thursday the 6th of August might be the best of a bad bunch. The morning is glassy – a total rarity – with a 5ft ESE swell, still a short 6-second period, but an energy of 124. It’s surfable, but very ordinary. The afternoon drops off a bit.
After that, it’s back to choppy, cross-onshore junk on the 7th. This spot is inconsistent and sheltered, and this forecast proves it. There’s nothing here for a beginner (the 5ft is a bit much for a beginner anyway, and the quality is poor), and even the few small windows are just “surfable but very ordinary.” Honestly, the setup looks more interesting for a kite surfer than a paddle surfer on those days with a bit of swell and some cross-off wind.
Stay patient, folks. The forecasts can change.
Rusty.

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.

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.
