Alright folks, Rusty here with a look at what we’ve got on the horizon. To be honest, it’s a pretty grim run of it for the next couple of weeks. The swell window is just not cooperating, and the wind is making a mess of things.
Kennack Sands is the only spot showing up, but it’s a tough watch. It’s an inconsistent, sheltered beginner’s break, and for the first week and a half, the wind is ruining everything. Saturday the 11th kicks off with lumpy, cross-onshore winds and an east swell around 4ft, with a weak combined energy of just 111. It stays messy right through the middle of the week, with a spike of 12ft on Monday 13th (energy at 1687, which is strong), but it’s blown out by a near-gale cross-onshore wind – that’s expert-only, if anyone even bothers.
Things turn a corner around Thursday the 17th with a clean, glassy offshore wind from the NW, but the swell drops to a tiny 0.7ft. The water temperature at Kennack is nothing unusual for this time of year, but you won’t care because there’s no wave to paddle into. From Saturday the 18th through to the 25th, it’s a real desert. There’s a little pulse of 3ft ESE swell on Friday the 24th with fresh offshore winds, which is the best you’ll get – but that’s still tiny and short-period (5 seconds), not really worth the wetsuit. The combined energy on that day sits at a weak 54.
Honestly, there are no standouts here. The whole 16-day window is a write-off for any decent surf. If you’re desperate for a splash, the 24th offers the cleanest conditions on the smallest of waves. Otherwise, leave the board in the van and go for a hike. Forecasts can change, but this blank run looks set.

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.

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.
