A season is an approximately three-month regularly recurrent periods into which the year is divided by the equinoxes and solstices or atmospheric conditions, Typically in temperate regions, the year is divided into four seasons: spring, summer, autumn (fall), and winter. Each season is classified by length of day and is characterized by specific meteorological or climatic conditions. Particular events or changes occurs in the different seasons as in plant growth and temperature. In the temperate and polar regions, seasons are marked by changes in the amount of sunlight, which in turn often cause cycles of dormancy in plants and hibernation in animals. These effects vary with latitude, and with proximity to bodies of water.

At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons. When it is summer in the Northern hemisphere, it is winter in the Southern hemisphere,  and when it is spring in the Northern hemisphere it is autumn in the Southern hemisphere.

In tropical and even subtropical regions, there is no noticeable change in the amount of sunlight. it is more common to speak of the rainy (or wet, or monsoon) season and dry season, as the amount of precipitation and wind may vary considerably than the average temperature.
In the tropics many regions are subject to monsoons rain and wind cycles.
