WINTER The cold weather season begins from mid –

November in northern India and stays till February. December and January are the coldest months in the northern part of India.

This season is important for Rabi crops. The weather is normally marked by clear skies, low

temperatures and low humidity and feeble variable winds.

The Cold Weather Season

RABI CROPSThe winter Crops

Rabi Crops :- Rabi crops are sown in winter from October to December. Harvested in In summer from April to June Important Rabi crops – wheat, barley, peas, gram, and

mustard. Grown in – States from North and North western parts

such as Punjab, Haryana, Himachal Pradesh, Jammu and Kashmir, Uttaranchal and Uttar Pradesh

Availability of precipitation during winter months due to western temperate cyclones helps in the success of these crops.

SUMMER Summer is the hottest of the four temperate seasons. Summer generally starts from the month of March and

continues up to May. The date of the beginning of summer varies according to

climate, tradition and culture. When it is summer in the Northern Hemisphere, it is winter

in the Southern Hemisphere, and vice versa.

LOO

The Loo is a strong, hot and dry summer wind from the west which blows over the western Indo-Gangetic Plain region of North India and Pakistan.

 It is especially strong in the months of May and June.

Due to its very high temperatures (45 °C–50 °C or 115°F–120°F), exposure to it often leads to fatal.

Since it causes extremely low humidity and high temperatures, the Loo also has a severe drying effect on vegetation leading to widespread browning in the areas affected by it during the months of May and June.
