The season of the year composing the transition period from winter to summer; the vernal season, during which the sun is approaching the summer solstice. In popular usage and for most meteorological purposes, spring is customarily taken to include the months of March, April, and May in the Northern Hemisphere, and September, October, and November in the Southern Hemisphere. Except in the Tropics, spring is a season of rising temperatures and decreasing cyclonic activity over continents. In much of the Tropics, neither spring nor fall is recognizable, and in polar regions, both are very short-lived.

The season of the year which occurs as the sun approaches the summer solstice, and characterized by increasing temperatures in the mid-latitudes. Customarily, this refers to the months of March, April, and May in the North Hemisphere, and the months of September, October, and November in the Southern Hemisphere.

Spring is one of the four seasons of temperate zones, the transition from winter into summer. Astronomically, some Western countries consider spring to begin with the vernal equinox (around March 20 in the Northern Hemisphere, and September 23 in the Southern Hemisphere), and ends with the summer solstice (around June 21 in the Northern Hemisphere and December 21 in the Southern Hemisphere). Such conventions are by no means universal, however.
