The climate of Bihar embodies the general climatic pattern of the Indian subcontinent. It shows a continental monsoon climate due to considerable distance from the sea.
The factors regulating the climate of Bihar are:
Its lying between 22-degree north to 27-degree latitude within a tropical to sub tropical zone.
The Himalayan Mountains in the north determine the monsoon rainfall.
Bihar connects with the Ganga delta and Assam.
The climate of Bihar is represented by the following seasons :
Cold weather season - December to February
Hot weather season - March to May
Southwest monsoon - June to September
Retreating southwest monsoon - October to November
The onset of the rainy season takes place when a storm from the Bay of Bengal passes through Bihar. However the monsoon may set in as early as the last week of May or as late as the first or second week of July. The winter days are warm and mild but after sunset, the temperature drops abruptly, creating a sense of sharp coldness. Average temperatures in November in Bihar range between 19.6°C to 22.26°C. with January usually the coldest month. The average minimum temperature is between 7.56°C to 10.56°C though temperatures in Netarhat even fall to 7.56°C.
Similar to most of northern India, Bihar witnesses thunder-storms and dusty winds in summer. The hot winds (loo) of Bihar plains blow in April and May averaging a speed of 8-16 kilometers per hour. The rainy season begins in June. The rainiest months are July and August. In three particular zones, rainfall surpasses 1800 mm. The south-west monsoon normally retreats in early October and is accompanied by tropical cyclones arising in the Bay of Bengal and typhoons from the south China sea.
