The Lowdown
Alright, let’s have a look at what’s cookin’ for the next couple of weeks. Gotta be honest, it’s a pretty bleak stretch for Kennack Sands. The models are showing a whole lot of nothin’, and the few pulses of energy that do show up just don’t line up right. We’ve got a 16-day window, but the first week is basically a total loss. There’s a gap from right now all the way through till the 10th of September with no real surf to speak of. The water is hangin’ at about 65°F, which is a touch warmer than usual for this time of year, so at least the wait won’t be too cold.
The first hint of anythin’ rideable comes on Thursday, the 10th of September. The morning is a dud, but the afternoon shows a little bump. We’re lookin’ at a 1.1m swell from the SSW, with a short period of 5 seconds and a weak energy readin’ of 64. The wind is a gentle cross-offshore from the NNW, which will keep it clean. It’s tiny, inconsistent, and sheltered, so it’s not a standout, but it’s the first sign of life after a long dry spell.
The real interest, and the only true standout in this whole outlook, happens on the 13th and 14th of September. Now we’re talkin’ about a proper shot of energy. The swell builds hard from the east, with heights pushin’ 1.9m to 2.4m. The combined energy jumps up to 275 on the Sunday, then 392, and by Monday morning we’re lookin’ at a meaty 576. That’s moderate to strong wave energy, and it’s got some weight behind it. The period is short at 6 to 7 seconds, so it’s windswell, not groundswell, and it’ll be a bit lumpy. The big problem here is the wind direction. It’s comin’ from the ENE to E, which is cross-onshore at best, and the forecast says “poor surf conditions” across the board. The break is sheltered, and with a cross-shore or cross-onshore wind, it’ll be choppy and messy. For a beginner, 1.9m is already too big, and over 2.5m is expert-only, so this is a setup for experienced surfers only, and even then, it’s gonna be a battle. The east swell direction is not the optimum (SSW), so it’s not hittin’ the break how you’d want. Honestly, this looks more interesting for the kite surfers than paddle surfers, given the power and the lumpy wind conditions.
So, to wrap it up: you’ve got nothin’ until the 10th, a tiny clean window, and then a powerful but messy few days from the 13th. If you’re desperate, the 10th afternoon might give you a few clean little ones, but the real energy is a rough, wind-affected mess. The area is inconsistent, and this blank run is a bit more normal for Kennack. Forecasts can change, but right now, it’s a tough watch.

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.
