The Lowdown

Alright, folks, Rusty here. Let’s be straight with you: this 16-day stretch for Kennack Sands is a tough one. We’re looking at a whole lot of “poor surf conditions” on the board, and honestly, the swell just isn’t showing up. The forecast is pretty bleak, with the first solid recommendation not even on the cards until August 22nd. That’s a solid two-week gap with basically nothing worth paddling out for. The waves are tiny, and the wind is mostly cross-onshore or just messy for the majority of the window. It’s one of those runs where you might want to wax the longboard for a splash-around, but there’s no real surf on offer.

The only real blip of interest is on August 12th. That’s a Tuesday, and we see the swell energy pick up to a moderate 42 and 53 (combined energy) in the morning and afternoon. The swell is coming from the east at 3ft. But the wind is cross-onshore from the ENE and E at 12-18 mph, which is going to make it choppy and lumpy. It’s still not good, but it’s the most energy the ocean shows for a while. It’s not a recommendation, just the only time there’s anything to look at before the next week.

Now, the one true standout – and we’ll call it the best on offer, but with a huge dose of caution – is August 22nd. It’s a Saturday, and we finally get conditions that line up. The morning is cross-off with a NNE breeze at 12 mph, and the afternoon turns properly glassy with a light NE wind of only 3 mph. The swell is small, just 0.7ft, but it’s a long-period groundswell from the SSW (15 seconds). That longer period gives it some shape. This is a sheltered spot, and it’s inconsistent, so you’ll be waiting for sets, but the clean, glassy afternoon makes it the pick of the whole period. It’ll be tiny, but clean and rideable.

Before that, on August 19th and 20th, we see a hint of this SSW groundswell (16-second and 14-second periods respectively) and 0.7ft waves, but the winds are stronger and cross-off, making it less clean. They’re promising signs, but not the standouts.

So, there you have it. This is a barren outlook. Kennack is inconsistent anyway, so a blank run like this isn't abnormal, but it's still a drag. Keep your eye on the 22nd; that’s your best chance for a glassy, tiny wave. Don’t hold your breath for anything else.

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.
