Spring is the first season of the year, roughly taking the equinox as it's midpoint and continues until early May, most areas have climates better described in terms of other seasons. When Spring comes, everybody feels warm and comfortable.
Springtime is seen as a time of growth, renewal, of new life being born. It begins to warm significantly. Snow begins to melt and run off. Frosts become less severe. In climates that have no snow and rare frosts, the air and ground temperatures increase more rapidly. Many flowering plants bloom this time of year.
Spring is a season of rebirth and renewal, everything begins to recovery. So it is the most beautiful season on earth. It is also my favorite season.
