The Lowdown
Right, let’s have a look at what’s on offer around here.
Alright, talkin’ straight, it’s a bit of a slow start. We’re looking at a long gap with pretty much nothing worth paddlin’ out for. From now, all the way through to the morning of Tuesday, August 4th, it’s flat or tiny. You’ll see some small pulses, but the wave comment says it’s all “poor surf conditions” and the scores back that up – not worth wetting a wetsuit for.
Kennack Sands is our only spot in the game, and it’s a sheltered, inconsistent beginner wave that doesn’t fire often. It breaks best on a SSW swell direction, but nothin’ in the first week lines that up right.
The water temperature is a real head-turner, though. At 68°F, that’s 6°F warmer than normal – much warmer than usual for the time of year. You won’t need a thick wetsuit, that’s for sure.
So, the first real chance of any surf whispers kicks off on the morning of Tuesday, August 5th. We’ve got a small bump of 2ft coming from the E with a short period of 7 seconds – that’s windswell, not much grunt. Combined wave energy is weak at 33. Wind is onshore from the SSE at 12 mph, so it’ll be a bit lumpy. Not for beginners, and not really a standout.
The one and only standout in this whole 16-day window falls on Monday, August 11th – that's more than a week away, so treat it as promising but not locked in. The afternoon of the 11th shows a solid 3ft swell from the SSW at 7 seconds. The combined energy hits 105, so there’s some moderate juice behind it. The wind turns NW at 16 mph and goes offshore, which will groom the faces nicely. That’s the best we’ll see: clean, offshore lines at Kennack Sands with a swell direction that actually matches the break’s optimum. The water will still be warm, and crowds are “sometimes” – so you might get a few locals out, but it won’t be a zoo.
For the rest of the run, it’s flat or tiny again after that. The 12th drops off to nothing. This spot is inconsistent as it is, so a blank run like this isn’t out of the ordinary. Forecasts can always change, but right now, keep your wax in the car for that Monday.

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.
