The Lowdown
Hey, Rusty here. Let’s talk about Kennack Sands for the next couple weeks. Honestly, it’s a tough one. This break is an inconsistent, sheltered beginner spot, and we’re looking at a real dry run.
The week kicks off with almost nothing. On Friday the 17th, there’s a tiny 1ft wave from the east with a real short 6-second period. The energy is weak (13), and it’s just not doing anything. Saturday the 18th and Sunday the 19th are either flat or blown out with onshore winds.
Into the next week, we get some tiny bumps. Monday the 20th has a 1ft windswell, and Tuesday through Thursday (21st to 23rd) have small 0.3ft southern pulses with some long periods up to 16 seconds, but the swell height is so small it’s a non-event. The wind goes clean or offshore a few times, but you need water to surf. The water temp is sitting at 66°, which is 4° warmer than average for this time of year.
Then from Friday the 24th of July all the way to Saturday the 1st of August, it’s a total shutdown. Day after day of flat, clean water. For a break that’s already inconsistent, this kind of blank stretch is pretty normal. Don’t get your hopes up, but forecasts can always change. Right now, though, there’s nothing doing.
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.
