The Lowdown

Alright folks, Rusty here. Let’s be straight with you – the outlook for Kennack Sands is a bit of a bummer for the next couple of weeks. We’re looking at a long, dry spell with hardly any surf on offer. The first real chance of a wave is a tiny blip on Tuesday, August 11th, but even then it’s nothing to write home about.

The whole 16-day window is basically a write-off for decent waves. From now until around the 11th, it’s mostly flat or close to it. The water temperature is sitting at 66°, which is a touch warmer than normal for this time of year – a nice thought, but you’ll be doing more floating than surfing.

The only period with any activity at all kicks off on Tuesday, August 11th. Through the morning, we’ve got a slight pulse of 2ft swell from the east, with a short, weak period of 4 seconds. The combined energy is a measly 10 (weak). The wind is cross-onshore out of the ENE, so it’s going to be fairly choppy. That afternoon, the swell sticks around 2ft from the east, period still 4 seconds, energy a bit higher at 13 – still weak, but the wind picks up to a moderate cross-onshore, making it choppy. This is not the day to bring a log.

Wednesday, August 12th sees the same 2ft east swell, but the wind gets nasty. A strong breeze from the east at 25 mph in the morning makes it messy, and a fresh breeze of 22 mph in the afternoon keeps it lumpy. The energy is still weak, ranging from 18 to 27. This is more kite-surfing weather than paddle surfing, to be honest.

After that, it fades away again. Thursday, August 13th drops to 0.7ft from the east, and by Friday, August 14th we’re back to a tiny 0.3ft south swell with a long period of 13 seconds, but energy is only 3 – barely a ripple. The wind is light and clean on Friday afternoon, but there’s no wave to ride.

The same story repeats into the weekend and the start of the following week. A few 0.3ft pulses from the south with periods up to 17 seconds, but the energy never gets above 12. The winds are often clean or offshore, but without any swell, it’s just a flat, pretty ocean.

Let’s be honest, Kennack Sands is a sheltered spot and inconsistent at the best of times, and these blank runs are more normal for the area. The forecasts can change, but right now, there’s nothing to get excited about.

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.
