The Cold Weather Season (Winter):

• The winter season begins from mid-November and stays till February; in northern India. December and January are the coldest months in the northern part of India. The temperature ranges between 10°-15°C in the northern plains, while it ranges between 24°-25°C in Chennai.
• The northeast trade winds prevail over the country in this season. As these winds blow from land to sea, most parts of the country experience a dry season.
• The weather is usually marked by clear sky, low temperatures and low humidity and feeble variable winds.

The Hot Weather Season (Summer)

• The summer season is from March to May. During this period, the global heat belt shifts towards north because of the apparent northward movement of the sun.
• During summer, the temperatures rise and air pressure falls in the northern part of the country. Towards the end of May, an elongated low-pressure area develops in the region which extends from the Thar Desert in the northwest to Patna and Chhotanagpur in the east and southeast.
• A characteristic feature of the hot weather season is the ‘loo’. These are strong, gusty, hot and dry winds which blow during the day over the north and northwestern India.

Advancing Monsoon (The Rainy Season)

• The rainy season begins from early June.
• The low-pressure condition over the northern plains intensifies at this time. It attracts the trade winds from the southern hemisphere. These south-east trade winds cross the equator and blow in a south-westerly direction to enter the Indian peninsula as the south-west monsoon. These winds bring abundant moisture to the subcontinent.
• These winds blow at an average velocity of 30 km/h. The monsoon winds cover the country in about a month; barring the extreme north-west.
• The windward side of the Western Ghats receives very heavy rainfall, early in the rainy season. The Deccan Plateau and parts of Madhya Pradesh also receive some rain, in spite of lying in the rain shadow area.
