The Lowdown
Right folks, Rusty here. Usually I’d be buzzing to get this out, but I gotta be straight with you – the next 16 days are looking real quiet for a paddle. The only spot in the frame is Kennack Sands, and it’s a tricky one.
Right now, and for the long haul, we’re dealing with a severe lack of swell. The wave energy is barely a whisper, often sitting at single digits (1) or just a few points. This is a sheltered spot, exposed to the south-southwest, but the swell we’re getting is tiny, mostly from the east or south, and the periods are all over the shop – some long 16-second groundswells, but with practically no height, it doesn’t matter. The water temp is about what you’d expect for the time of year.
The first real chance of anything comes on the morning of Thursday, July 31st. We’ll see a bump in energy with a combined swell energy reading of 117 (moderate), and waves up to 4ft from the east-southeast, but here’s the kicker: it’s a cross-shore wind from the south-southwest at 12 mph, making it look messy. That afternoon, it actually gets a touch bigger to 5ft with energy up to 194 (moderate), but the wind stays cross-shore. This is a beach break, and with that size and wind, it’s honestly shaping up more interesting for kite surfing than a classic paddle session. It’s also getting too big for beginners.
Friday morning, August 1st, the swell drops back to 3ft (energy 34), and the cross-onshore wind from the south at 12 mph keeps it choppy. The rest of the run is flat or near-flat, with only tiny dribbles of energy. The second week offers nothing but clean, small, unrideable conditions.
It’s a blank run for the area. A few days with no surf, then a couple of days of marginal, onshore slop, then back to nothing. You’d be better off waiting for a change in the charts.
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. 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.
