Geography of Nepal

Geography Of Nepal


Nepal is located in 
South Asia between China in the north and India in the south, east and west. While the total land area is 147,181 sq. km including water area of the country that is 3,830 sq. km. The geographical coordinates are 28°00′N 84°00′E. Nepal falls in the temperate zone north of the Tropic of Cancer.Nepal’s ecological zones run east to west about 800 km along its Himalayan axis, 150 to 250 km north to south, and is vertically intersected by the river systems. The country can be divided into three main geographical regions: Himalayan region, mid hill region and Terai region. The highest point in the country is Mt. Everest (8,848 m) while the lowest point is in the Terai plains of Kechana Kalan in Jhapa (60 m).
The Terai region, with width of ranging 26 to 32 km and altitude ranging from 60 -305 m, occupies about 17 percent of total land area of the country. Kechana Kalan, the lowest point of the country with an altitude of 60 m, lies in Jhapa district of the eastern Terai.The southern lowland Terai continues to the Bhabar belt covered with the Char Kose Jhadi forests known for rich wildlife. Further north, the Siwalik zone (700 – 1,500 m) and the Mahabharat range (1,500 – 2,700 m) give way to the Duns (valleys), such as Trijuga, Sindhuli, Chitwan, Dang and Surkhet. The Midlands (600 – 3,500 m), north of the Mahabharat range is where the two beautiful valleys of Kathmandu and Pokhara lie covered in terraced rice fields, and surrounded by forested watersheds.
The Himalayas (above 3,000 m) comprises mountains, alpine pastures and temperate forests limited by the tree-line (4,000 m) and snow line (5,500 m). Eight of the 14 eight-thousanders of the world lie in Nepal: Sagarmatha or Mount Everest (8,848 m), Kanchenjunga (8,586 m), Lhotse (8,516 m), Makalu (8,463 m), Cho Oyu (8,201m), Dhaulagiri (8,167 m), Manaslu (8,163 m) and Annapurna (8,091 m). The inner Himalayan valley (above 3,600 m) such as Mustang and Dolpa are cold deserts sharing topographical characteristics with the Tibetan plateau.Nepal holds the so called “waters towers of South Asia” with its 6,000 rivers which are snow-fed or dependent on rain. The perennial rivers include Mahakali, Karnali, Narayani and Koshi rivers originating in the Himalayas. Medium-sized rivers like Babai, West Rapti, Bagmati, Kamla, Kankai and Mechi originate in the Midlands and Mahabharat range. A large number of seasonal streams, mostly originating in Siwaliks, flow across the Terai.
Of 163 wetlands documented, the nine globally recognized Ramsar sites are: Koshi Tappu Wildlife Reserve, Beeshazarital (Chitwan), Jagdishpur Reservoir (Kapilvastu) Ghodaghodi Tal (Kailali) in the Terai, and Gokyo (Solukhumbu), Phoksundo (Dolpa), Rara (Mugu) and Mai Pokhari (Ilam) in the mountain region.There are more than 30 natural caves in the country out of which only a few are accessible by road. Maratika Cave (also known as Haleshi) is a pilgrimage site associated with Buddhism and Hinduism. Siddha Cave is near Bimalnagar along the Kathmandu-Pokhara highway. Pokhara is also known for caves namely Bats’ shed, Batulechar, Gupteswar, Patale Chhango. The numerous caves around Lo Manthang in Mustang include Luri and Tashi Kabum which house ancient murals and chhortens dating back to the 13th century.

Climate of Nepal

Climate Of Nepal


Climatic conditions of Nepal vary from one place to another in accordance with the geographical features. In the north summers are cool and winters severe, while in south summers are tropical and winters are mild. Nepal has namely five major seasons: spring, summer, monsoon, autumn and winter.An average temperature drop of 6°C occurs for every 1,000 m gain in altitude. In the Terai, summer temperatures exceed 37° C and higher in some areas, winter temperatures range from 7°C to 23°C in the Terai. In mountainous regions, hills and valleys, summers are temperate while winter temperatures can plummet under sub zero. The valley of Kathmandu has a pleasant climate with average summer and winter temperatures of 19°C – 35°C and 2°C – 12°C respectively.
The Himalayas act as a barrier to the cold winds blowing from Central Asia in winter, and forms the northern boundary of the monsoon wind patterns. Eighty percent of the precipitation is received during the monsoon (June-September). Winter rains are more pronounced in the western hills. The average annual rainfall is 1,600 mm, but it varies by eco-climatic zones, such as 3,345 mm in Pokhara and below 300 mm in Mustang.An interesting fact is that there is no seasonal constraint on traveling in and through Nepal. Even in December and January, when winter is at its severest, there are compensating bright sun and brilliant views. As with most of the trekking areas in Nepal, the best time to visit are during spring and autumn. Spring is the time for rhododendrons while the clearest skies are found after the monsoon in October and November. However, Nepal can be visited the whole year round.
Here’s a brief view of the average temperatures and rainfall during peak summer and winter in three most popular tourist areas:
