The Lowdown
Right then, let's have a look at what's on the table for the next couple of weeks. I'll be honest with you, mate, it's a pretty quiet stretch. Kennack Sands is the only spot we've got to talk about, and it's a sheltered, inconsistent little cove, so we're not exactly expecting a swell magnet. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.
We kick off on Tuesday, the 1st of September, with nothing doing. The swell is tiny, barely a ripple, and the wind is messy. That's the story for most of the first week, really. We get a few moments of clean conditions with a light offshore on Friday the 4th, but the swell is still a pathetic 0.7 ft from the SSW. It's a long period groundswell, 14 seconds, but there's just no size to it. The combined energy is a measly 21 (weak), so it's more of a paddle and a tan than a surf. The whole period from the 1st to the 10th of September is a write-off, with scores of zero across the board. A long, dry gap.
Then, on Friday the 11th of September, things try to stir a little. We get a bit of a bump, 3 ft, but it's a short-period, 6-second windswell from the SSW, and the wind is a fresh cross-onshore. It's going to be lumpy and messy. The energy picks up to 56 (weak), but the quality just isn't there.
The only time we see anything with a bit of oomph is on Saturday the 12th of September. The morning has a 4 ft swell from the east, with a combined energy of 120 (moderate). That's the most promising number we've seen all forecast. But the period is a dreadful 6 seconds, and the wind is a fresh cross-shore, creating a lumpy cross-chop. It's a beach break, so that short-period, wind-affected swell is going to be a real close-out mess. For a beginner or a learner, 4 ft might be pushing it, and for anyone else, the quality is just poor. I'd say this is more interesting for the kite surfers than anyone on a paddle board.
After that, it fades right back to nothing. We get a glassy morning on Wednesday the 16th of September, with a long-period 16-second groundswell, but it's only 0.3 ft. The energy is 5 (weak). It's a beautiful, clean window, but with absolutely no swell to ride.
So, the honest truth is, there's no standout here. The best on offer is that Saturday the 12th with the 4 ft, but it's a poor-quality, windy mess. If you're desperate for a paddle in clean water, that glassy morning on the 16th is your best bet, but you won't be catching any waves. Otherwise, this is a proper blank run for the area. Forecasts can change, but this one is looking pretty grim.

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.
