Was down at Yals on the weekend and there was this cool looking mist rising up the coastal hills looking north?

Low level cloud?

Wind blowing over the warm water picks up more moisture than the air can hold as it cools down on contact with the cooler land.
was it early in the morning following a clear night?

I think that pressing fast forward on your camera does it.

that be the stuff that rusts everything. salt laden air has nowhere to move and kinda condenses a bit as the land rises. best i can think of.

Like I said, low flying cloud

Ah what you have photograph is probaly nimbostratus or stratocumulus cloud formation. (Low level clouds or mid).by the looks of the pic these clouds will harvest tiny water droplets or crystalised water depending on the air mass temp.one will ask how l know all this my son is studing nephology at the moment .These clouds are usually at a attitude of between 5000 mtrs to 18000 mtrs.enough said.

more like 5000 ft plus.
cloud base last weekend of nimbo and stratus was 2000ft!
how do i know this? i was falling through them after flying around them. and i got wet.
its the mist rolling up the hills i thought was the topic being discussed though. i thought?.

Nimbo/nimbus, means rain bearing. Cumulus is well cumulating -growing, gathering, getting bigger usually vertically- hence a cumulonimbus (Cb) is a rain bearing cumulus cloud.
Unless I was looking at something else on the video, I don't believe it is either nimbostratus nor stratocumulus.

Saltiest1, so what you would've fallen through was nimbostratus.

It can happen on fresh water as well, it usually signals the arrival of a mystic.

well what ever they were some of them were stacked to about 10000 ft. they're the ones we wing suit down the face of while aiming for a hole some place. accidentally fly into one (something to avoid) and you are wet. most of them were 2 to 5 k in thickness and thick.
it gets a few of us smilng back on the ground.

Yes,.. t's usually the simplest answer, and we got it in the first reply.

It really is just low level cloud. Sometimes called scud. Usually about one or two octas cover, and quite thin, only a few hundred feet thick.

No, not low level cloud...

I originally thought condensing moisture forming fingers of fog (or low level cloud), but it really seems to start at the breaking waves, so I am actually with those thinking is it ocean spray being carried up with the wind. ie no condensation has occurred, just water droplets taken or thrown up from the ocean surface being picked up and carried along.

After pweedas comment about scud I went back and watched it again and again like they do in those cop shows. I think people are looking at two different things. It is made harder by the movie having been sped up. But, I couldnt before see the "low cloud" and "scud" over what I was looking at, being what I think is sea spray.

Im in cloud 9.its just mist with h20 in it.

+1 for saltwater spray from breaking waves. You can calculate how far inland you are if you carefully measure the salinity of rainwater... More salt in coastline rain from sea spray.

Oh,.. I seeee,...
You're right of course.

I should have paid more attention to the bit wot said,.. "mist rising up the coastal hills",.. and yes, that is definitely salt spray mist blown off the waves.

salinity of rainwater? Rainwater, rain comes from clouds doesn't it

Same as acid rain. It condenses pure then picks up the salt in the air as it falls.

yes tp1, but that moisture comes from evaporation,and the evap has some salt in it.
give it a few million years and it runs downstream into the lowest point and creates massive salt lakes for you to sail on

Not sure you have it right there. Evaporated moisture is pure H2O. It recondenses as pure H2O. It only picks up other elements if they are suspended in the air as it condenses then falls. eg - Salt spray near the ocean or sulphur from smog forming hydrogen sulphide as acid rain.

Also salt lakes are formed from salt already present in the ground being picked up by surface or subsurface water flow. Usually left over from evaporated oceans - eg central Australia used to be a seabed....

That's right.
The mist in the above vid has not evaporated off the ocean.
Mist which comes from evaporation has no salt in it. None at all, because the salt is left behind in the ocean when it evaporates.
but,.. the mist in the vid did have salt in it because it was formed from the trillions of bubbles which are caused when the waves break.
Every bubble bursting at the surface ejects a very small sea water droplet, which has 4% salt in it.
It's this mist of sea water which is shown in the vid, being blown up the hill side. It's not evaporated water.
As it blows inland, the water in the droplets evaporates and leaves microscopic salt particles which are so small and light, they just drift miles inland in the air, sometimes at quite high altitude.
They can eventually act as a nucleaus for rain drops to form around, or if they are at low altitude, they are cleaned out of the air by rain falling through them and end up on the ground.
The overall salt content of this rain is very small, but over thousands of years, if it hasn't been able to drain back into the sea, it all adds up until the land and sub surface water can be as salty as sea water.
