Dew forms on any exposed and thin object in the morning and (unknown to some) also in the evening. It is caused by the object cooling. When it cools it radiates the heat it is generating. That heat causes moisture in the surrounding atmosphere to condense. The water is not able to evaporate faster that it is condensing. So, dew forms.
The dew-bead - Gem of earth and sky begotten. – George Elliot (nee Mary Ann Evans)
Dew still forms in the winter, or when temperatures lower enough, in its icy form – we know it as frost. The formation of dew is intimately related to the temperature of the surfaces on which it will form. Surfaces which are not warmed from deep ground heat, such as leaves and railings are therefore more susceptible to the formation of dew.
The dew of compassion is a tear - Byron
The most likely time that dew will form is when there are not many clouds in the sky. As the moon can then be seen the night before dew appears it has become connected with the phenomena in many folk histories. Even today, many associate dew with fairies having been playing in the garden during the night.
What Youth deemed crystal, Age finds out was dew – Robert Browning
Most parts of the world do not have climates where the amount of dew produced can possibly compete with the amount of rain. In some places with long dry seasons some plants have adapted so they can make the most from the dew fall. These include pine seedlings and some lichens.
I must go seek some dew-drops here,
And hang a pearl in every cowslip's ear. - Shakespeare
Man's life is like a drop of dew on a leaf. - Socrates
Irish legend has it that you should go out on Beltane morning and gather up dew in a bowl. If the dew is used to wash your face with you will have a perfect complexion by the next day. Don’t put the alarm clock on for an unearthly hour tomorrow – there is no medical evidence to back this up! Dew was also used in ritual, particularly those relating to the moon.
The person who doesn't scatter the morning dew will not comb gray hairs – Hunter S Thompson
In Greek mythology, Ersa is the goddess of Dew. She is the daughter of Zeus and Eos, the goddess of the dawn. Eos would rise each morning to greet Helios, the god of the sun. She would open the gates of heaven for him so he could ride across the sky.
