The air near the ground cools to the DEW POINT.

DEW
When water vapor reaches its dew point it then becomes saturated. Either the vapor falls as rain, or if it is a cool clear night it forms as dew on surfaces. if the surface is cold enough it can also form as frost.
dew
Those drops of water are called dew. Dew forms when the temperature of the surface cools down and reaches the dew point, causing water vapor in the air to condense and form small droplets.
Condensation of water vapor causes dew.
dew, due, do
That depends entirely upon where you are in the world but dew is unconnected to time of year as such. It forms when it cools enough at night for the RH to get to 100%. In some parts of the world that could be every night, in others never or very rarely.
These are called dew drops. They form when the temperature of the surface cools down causing water vapor in the air to condense and form small droplets of water. Dew is more likely to form on clear, calm nights when the temperature drops close to the dew point temperature.
When dew forms in the winter, it forms at night and its colder at night so the dew freezes at that point in freezing.
