Table - best surf conditions forecast for Kennack Sands over the next 16 days.
Alright folks, Rusty here. Let's be straight with you – this outlook for Kennack Sands is a tough one. We're looking at a real flat spell for the entire 16-day window. There's nothing on the menu that's going to get you excited, so let's just walk through what we're dealing with.
The water's sitting at 64°, which is a notable 4° warmer than usual for this time of year – feels like a bathtub, but unfortunately, there's no swell to go with it.
We kick off on Thursday, July 9th, with some glassy conditions but the swell is a measly 0.3ft. The combined energy is a paltry 9 – that's about as weak as it gets. It's a no-go. Friday the 10th and Saturday the 11th bring a little more height, up to 4ft on Saturday morning, but the wind is a cross-on mess from the east, making it choppy and lumpy. The energy climbs to 114 on Saturday, but the quality is just poor.
Sunday the 12th sees the biggest swell of the period, hitting 8ft in the afternoon (combined energy of 708). But it's a strong cross-onshore wind from the east, turning it into a messy, blown-out wall of white water. This is more a kite-surfing setup than a paddle-surfing one. Monday the 13th is even bigger, with 12ft morning surf and a near-gale wind – that's a hard pass for everyone.
From Tuesday the 14th onwards, the swell drops off a cliff. We get a couple of days of clean offshore winds from the northwest on the 16th and 17th, but the swell is only 0.7ft to 1ft. The energy is in single digits. The rest of the run, right through to July 24th, is virtually flat. The wind is often clean, but there's just nothing to push into the beach.
So, there are no standouts here. No best day. This is a classic blank run for a sheltered spot like Kennack Sands. It's a waiting game, but the forecasts can change, and it won't be poor forever.
Rusty.
