1.  The Cold Weather Season (Winter): The cold weather season begins from mid-November and stays. February in Northern parts of India with December and January as the coldest months. The temperature decreases from South to North. For instance, the average temperature of Chennai, on the Eastern coast, is between 24°—25°C while in Northern plains, it range between 10°—15°C. During this season, days are warm and night are cold. Frost occurs in the Northern plains and snow falls in the high mountainous regions of Himalayas. As the North-East trade winds blow during this period, most of the country remains dry as they blow from land towards sea. The only rain occurs in Tamil Nadu and Southern Andhra Pradesh due to these winds picking up moisture from the Bay of Bengal.

Features of Cold Weather Season: The characteristic features are:

  • A feeble (weak) high pressure region develops in the Northern part of the country. Influenced by the relief, the light winds moving outwards from this area blow through the Ganga valley from the West and the North-West.
  • Clear sky, low temperature and humidity, and feeble, variable winds are the characteristics of the weather during the period.
  • There is an inflow of cyclonic disturbances from the West and the North-West, which have originated over the Mediterranean Sea and Western Asia. They cause winter rains over the plains and snowfall in the mountains. This winter rainfall though in small amount is locally known as Mahawat. It is useful for cultivation of the Rabi crops.
  • The peninsular region has moderating effect from sea and hence, it doesn’t have well defined cold seasons. Also there is hardly any noticeable change in temperature pattern.
