I know it's some kind of water vapour, but why is it sometimes thicker than others etc - today you can hardly see your hand in front of your face here in Berkshire...

There are 5 types of fog. Each has a different cause.
Radiation Fog - occurs under clear, calm skies when infrared radiation (heat) escapes to upper atmosphere and outer space and the air is cooled to its dewpoint. Sometimes called valley fog or ground fog and is the most common fog over land in the world.
Advection Fog - occurs when warm, humid air is cooled to its dewpoint by coming into contact with a cooler surface below. Snow, ice, and cold water are common surfaces that cause advection fog.
Steam Fog - occurs when cooler air rests above warmer water and vapor that evaporates into the air cools to its dewpoint. Sometimes called Arctic sea smoke.
Upslope Fog - occurs when air is forced to rise up a large slope and cools (adiabatically) to its dewpoint. Common in mountainous states.
Frontal Fog - also knows as precipitation fog and occurs when rain drops fall into unsaturated, cooler air below. As the drops evaporate, water vapor is introduced into the cooler air. Very quickly, the vapor condenses into a small fog droplet.

"Fog is a cloud in contact with the ground. Fog differs from other clouds only in that fog touches the surface of the Earth. The same cloud that is not fog on lower ground may be fog where it contacts higher ground such as hilltops or mountain ridges."
It gets thicker depending on what type of fog it is...If you live near water, its most likely "steam fog" which is when cold air flows above much warmer water.

Fog is formed when water vapor is in the air and it condenses. Mist could mean low cloud. Don't get mixed up with the two

fog is a mixture of dust particles and water vapour. the water is adherent to the particulate matter.the more the suspended dust particles, the thicker the fog. in fact it is 'smog' a combination of smoke and fog.

low cloud meeting cold air and it is usually thicker where water is the more water, the more water vapour there is
