What is Season? As the year passes, there are regular changes in the weather. This cycle of change of weather is divided into four parts, which are called seasons. The four seasons are winter, spring, summer and autumn.
Summer and winter are the two most important seasons for students. These are the season's names you hear at the time of your holidays in school. We always wait for the summer and winter holidays in our school. Summer is the hottest season of the year, and winter is the coldest season of the year. Winter comes from an Old Germanic word meaning "time to water." It refers to the winter rain and snow.
The monsoon type of climate is found in India. The word monsoon is derived from the Arabic word Mausim, which means 'seasonal change in wind direction'. The weather or season of India is influenced by two types of winds – the winds coming from the Arabian Sea and the winds coming from the Bay of Bengal. The Indian Meteorological Department has divided the climate of India into the following four seasons – Winter, Summer, Monsoon and Autumn.

How Many Seasons in the World?
There are four main types of seasons in the world. The names of these seasons(four season name) are:
1. Autumn Season:
Autumn follows the rainy season starting from October and lasts till the beginning of December. It is often referred to as the 'Retreating Season' of the Southwest Monsoon due to its gradual withdrawal from India. Northern India does not receive rainfall during this season, but several cyclones occur in the Bay of Bengal, which moves from northwest to northeast along the east coast and brings rain over the Tamil Nadu coast and Sri Lanka.
2. Summer Season:
The summer season starts in March and lasts till June-July. At this time, due to the 'Summer Solstice', the whole of India experiences a temperature rise. In this season, extremely hot winds blow during the day in the north and north-west part of India, which is called 'Loo'. In this season the Sun turns north and the Inter-Tropical Convergence Zone (ITCZ) starts moving northwards and becomes situated above 250 North latitude in July.
During this season, when the warm and dry air of the land meets the moist winds of the sea, then cyclones are formed in that area. These cyclones are called pre-monsoon cyclones. These are extremely strong winds that bring heavy rain and hailstorms.
3. Winter Season:
The winter season starts in mid-November in northern India and lasts till February. In winter, the temperature starts decreasing as the temperature increases from south to north. The average temperature in this season ranges from 24° to 25° C on the east coast while it ranges from 10°–15° C in the plains of the north. The days are relatively warm and the nights relatively cool. Fog in the northern areas and snowfall on the upper slopes of the Himalayas is common in winter.
4. Rainy Season:
The rainy season starts in mid-June and lasts till September, and the rainfall during this season is related to the entry of the South-West monsoon into India. During this season, a low-pressure area is formed over the northern plains, attracting the southern hemisphere's trade winds. The southeast trade winds of the Southern Hemisphere cross the equator and blow in south-westerly direction to enter the Indian peninsula as the Southwest Monsoon.
With the arrival of the South-West monsoon in India, there is a complete change in the weather. Mawsynram, the southern range of the Khasi Hills, has the highest average rainfall in the world.
