The Lowdown

Alright folks, Rusty here. Let’s get into what’s cooking at Kennack Sands over the next couple of weeks.

To be straight with you, it’s a bleak outlook. The wave energy is barely a whisper for the first week and a half. The water is hanging around 64°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing your toes off, but that’s the only good news.

There’s a long, empty stretch with no real surf from now all the way through to the 23rd of September. I’m talking flat, or close enough that you’d be floating around for nothing. On the 23rd, a weak little pulse shows up – 3ft from the ESE, but with a useless 5-second period and a fresh cross-onshore wind making it lumpy. The energy is only 40 – that’s pathetic. Don’t bother.

The rest of the month stays grim. On the 26th, Saturday afternoon, we finally see the biggest swell of the whole forecast – a bit over 4ft from the ESE, but with a terrible 4-second period and a moderate cross-onshore wind, so it’ll be a choppy mess with energy at 86. For a sheltered beginner spot, that’s not beginner-friendly and the quality is completely wrecked. The 27th, Sunday afternoon, the wind turns offshore from the WNW, which is good, but the swell is back down to a weak 3ft with a 5-second period, so you’re looking at fat, weak waves. The 28th looks similar – clean offshore breeze but tiny 3ft swell with no period.

The best you’re gonna get in this run is the 27th afternoon into the 28th. Kennack Sands (Cornwall) will have the cleanest conditions of the whole stretch with a moderate offshore wind, but it’s on tiny 3ft swell. It’s a “maybe take the log out for a paddle” kind of day, but don’t expect any real rides. The combined energy is only 49.

This is a proper blank run for the area. Don’t get your hopes up. Forecasts can always shift, but right now, it’s a whole lot of nothing.

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.
