The Lowdown

Right, let’s be straight with you. I’ve had a good look at the charts for Kennack Sands, and honestly, mate, it’s a pretty bleak run for the next 16 days. There’s a real gap right at the start – nothing worth getting wet for at all from Sunday the 9th of August all the way through to Friday the 21st of August. That’s nearly two weeks of flat or hopeless conditions. The water is sitting at 67°F which is much warmer than normal for this time of year, but that’s about the only positive.

The first time you’ll even see a ripple is a tiny bump on the 21st of August – Friday afternoon. We’re looking at a 4ft swell from the east, but with a short period of 5 seconds, it’s not going to have any punch. The combined energy is only 99 (weak), so it’s weak. The wind is offshore from the northwest, which is clean, but the swell is so small and junky it’s barely surfable. It’s a forgettable session.

The only real standout in this whole forecast is far out – Sunday the 23rd of August. On the morning, we’ve got a 5ft swell from the SSW, with a period of 6 seconds, and the wind is offshore from the northwest. The combined energy jumps to 155 (moderate). That’s the biggest push we’ll see in the whole period. The direction from the SSW is a good match for the spot, and with light offshore wind, it’ll be clean. The swell is under 5ft, so it’s fine for a mix of abilities, but it’s a beach break, and with a short period, it won’t be a world-beater. Still, it’s the best on offer. After that, the next week is back to tiny, weak pulses with no quality.

To be honest, Kennack is a sheltered spot, and it’s inconsistent. A blank run like this is more normal for the area. Even the best day on the 23rd is just a “meh” little wave. If you’re desperate, you might get a couple of knee-high runners on the 23rd morning, but I wouldn’t hold your breath.

Rusty.

A general guide to surfing at Kennack Sands can be found by selecting the local surf guide option on the grey menu.

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).
