The Lowdown
Alright, Rusty here. Let’s talk about what’s on the cards at Kennack Sands.
Right now, the outlook is pretty grim. We’re looking at a long stretch of flat or near-flat conditions and poor surf quality. There’s nothing worth paddling out for from Tuesday the 25th of August all the way through to the end of the month. You won’t see a single decent wave in that time. The water is sitting at 65°, which is a touch warmer than normal for this time of year, but that’s about the only bright spot until we get to the last few days of the first week of September.
The only real chance for a wave shows up on the 7th of September. Monday morning brings a bit of a pulse – around 5ft of swell from the SSW, but it’s short-period stuff (5 seconds) and comes with a strong cross-shore breeze that will mess things up. The combined swell energy is moderate at (111), but the wind will chop it to pieces. This is really only for the dedicated local who doesn’t mind messy, lumpy conditions. It’s not beginner friendly at that size and state.
Before that, we have a few small clean windows. On the 31st of August morning, there’s 3ft from the SSW with fresh offshore wind from the NW – that’s clean, but tiny. Probably not worth suiting up for. The same goes for a stretch from the 2nd to the 5th of September where we see tiny 0.6ft groundswell with periods up to 16 seconds. Those long-period swells will break straight and be very weak, but the winds are offshore for the mornings on the 5th (NNW and NW). They’ll be glassy but the wave energy is negligible (combined energy as low as 14).
Honestly, this is a poor run. Kennack Sands is an inconsistent, sheltered beginner spot and it’s showing its true colours here. There is nothing close to a standout in the whole 16-day window. If you’re desperate for a paddle, maybe the 7th of September morning offers the only surfable bump, but don’t expect quality. The setup here looks more interesting for a kite session when the wind picks up than for a surf.
Keep an eye on the sky, but for now, don’t hold your breath.
Rusty.

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.
