Table - best surf conditions forecast for Kennack Sands over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you: this is a tough one for Kennack Sands. The whole 16-day stretch is a write-off for any decent surf, so I’m calling this one a blank run. The only break on the radar isn’t offering anything worth paddling out for.
We’ve got a dive in the deep end of the water temp anomaly, which is sitting at a very unusual 3° warmer than normal, hitting 66°F. That’s way above what you’d expect for this time of year, but it’s not going to make up for the lack of waves.
From Sunday 12 July right through to the end, the story is mostly poor surf conditions. On the 12th, we’ve got a 7ft swell from the east, but it’s short period at 7 seconds and cross-onshore winds at 25 mph. The energy is moderate (538) but it’s messy and blown out. Monday 13 July sees a bigger 10ft east swell with a period of 9 seconds and a strong 1510 energy reading, but with near gale cross-onshore winds at 31 mph, it’s a complete mess – only for the hardcore or the kite crew. The setup here is a beach, so with that much wind and swell, it’s honestly looking more interesting for kite surfing than paddle surfing.
The rest of the week is a slow fade. Tuesday 14 July has some 5-6ft waves, but still cross-onshore and lumpy. By Wednesday 15 July, the swell drops to a tiny 0.7ft, and from there we’re into a long stretch of flat or near-flat conditions. There’s a few days in the second week with some clean offshore winds, but the swell is barely a bump – 0.3ft to 0.7ft at best. Even Saturday 25 July shows a late 5ft from the SW, but with a short period of 5 seconds and 140 energy, it’s not going to be quality.
The break is inconsistent and sheltered, and this stretch of poor surf is normal for the area. There’s nothing to get excited about, but forecasts can change. For now, leave the boards at home.
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.
