The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s happening for the next couple of weeks.
To be straight with you, it’s a pretty flat run ahead. The forecast shows a lot of days with minimal swell and poor conditions, so we’re looking at a long stretch of quiet water. The first real week looks like a write-off, and then we have a few tiny pulses that don’t really offer anything for a proper paddle. It’s one of those spells where the ocean just takes a breather.
The only spot in the mix is Kennack Sands. It’s a beginner-friendly, sheltered little cove, but it’s also inconsistent and rarely breaks. Right now, it’s not doing much. The water temp is sitting at 64°, which is about 2° warmer than normal for this time of year – not a big deal, but a touch on the mild side.
From Wednesday the 2nd through to the end of the first week, we’re looking at tiny swell, mostly around 0.7ft to 1ft. The wind is often cross-off or cross-on, and the combined energy is weak, never hitting triple digits. The best of a bad bunch is Saturday morning the 5th, when it’s glassy with a light SSW wind, but the swell is still only 0.7ft. There’s a long 15-second period, but there’s just no power behind it. It’s essentially a flat calm. The following days have a little bump of 3ft on Sunday the 6th, but that’s from the SE with a short 5-second period and onshore wind – just messy, choppy junk.
After that, from Monday the 7th right through to the middle of the second week, it’s a total blank. Days and days of zero swell. The wind is often offshore or cross-off, but with nothing to work with, it’s just a flat ocean. The only thing to note is a brief, tiny pulse on the 8th and 9th, but we’re talking 0.3ft. It’s a no-go.
Then, on Thursday the 17th, we see a late spike. The afternoon shows a 4ft swell from the east with a 5-second period, and a strong offshore wind from the WNW. The combined energy hits 57, which is still weak. The wind is clean, but the period is so short it’ll be crumbly and weak. For a beginner spot, it’s small enough, but it’s not worth the wait.
Overall, there’s nothing to get excited about. It’s a long, flat spell. If you’re desperate for a paddle, Saturday morning the 5th is the only window with some glass, but don’t expect to catch much. Otherwise, the forecast can always change, but right now, this is a blank run.
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.
