Climate
Climatic conditions of Nepal vary from one place to another in accordance with their geographical features. In the north summers are cool and winters severe, while in the south summers are tropical and winters are mild. Nepal has five seasons: spring, summer, monsoon, autumn and winter.
In the Terai (south Nepal), 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 Kathmandu Valley has a pleasant climate with average summer and winter temperatures of 19°C – 35°C and 2°C – 12°C respectively.
Good to know is that on average temperatures drop 6°C for every 1,000 m you gain in altitude.
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 all the rain in Nepal 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.
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.
Plants
Of the total number of species found globally, Nepal possesses 2.80 percent plants. Record from 2006 shows that Nepal has 6,391 flowering plant species, representing 1,590 genera and 231 families. Nepal’s share of flowering plant species is 2.76 percent of the global total compared to earlier records of 2.36 percent. Nepal’s share of pteriodophytes is 5.15 percent compared to earlier records of 4.45 percent.
There are 2,532 species of vascular plants represented by 1,034 genera and 199 families in the protected sites. Some 130 endemic species are found in the protected sites.
For ecology and vegetation purpose Nepal could be divided into four floristic regions i.e.
(a) western
(b) north-western
(c) central, and
(d) eastern, and bio-climatically these are broken down into twenty regions from humid tropical climate to the arid, alpine regions.
There are 399 endemic flowering plants in Nepal of which about 63 percent are from the high mountains, 38 percent from the mid hills, and only 5 percent from the Terai and Siwaliks. Similarly, the central region contains 66 percent of the total endemic species followed by 32 percent in the western and 29 percent in the eastern regions.
Medicinal Plants:
The Himalayas are famous for medicinal plants and have even been mentioned in the Aurveda. Many of the herbs and plants found in the Himlayas are used in traditional healing systems like Ayurvedic, Homoeopathic, Amchi etc. Some of these plants are even used for allopathic medicine.

Orchids:
In ancient Rome, Theophrastus, a student of Plato, was intrigued by the sight of a plant with a pair of roots. Orchis was the name he gave them, the Greek word for testicles. Worldwide, there are some 500 to 600 genera and some 20,000 to 35,000 names, the largest of all plant families, and out of this, Nepal has 57 genera (27 Terrestrials and 30 Epiphytic) with a few Lithophytes.Nepal is endowed with an incredible variety of orchids scattered across the country. Dedrobium is the largest species, followed by Habenaria and Bulbophyllum. Anthogonium, Hemipilia and Lusia are some of the other varieties amongst the nearly two dozen single species families.
People
The population of Nepal was recorded to be about 26.62 million according to a recent survey done by the Central Bureau of Statistics, Nepal. The population comprises of about a 101 ethnic groups speaking over 92 languages. The distinction in caste and ethnicity is understood more easily with a view of customary layout of the population.Though, there exist numerous dialects, the language of unification is the national language, Nepali. Nepali is the official language of the state, spoken and understood by majority of the population. Multiple ethnic groups have their own mother tongues. English is spoken by many in Government and business offices. It is the mode of education in most private schools of Kathmandu and some other cities.
Northern Himalayan People:
In the northern region of the Himalayas are the Tibetan-speaking groups namely Sherpas, Dolpa-pas, Lopas, Baragaonlis, Manangis. The Sherpas are mainly found in the east, Solu and Khumbu region; the Baragaonlis and Lopas live in the semi-deserted areas of Upper and Lower Mustang in the Tibetan rain-shadow area; the Manangis live in Manang district area; while the Dolpa-pas live in Dolpa district of west Nepal.
Middle Hills and Valley People:
Several ethnic groups live in the middle hills and valleys. Among them are the Magars, Gurungs, Tamangs, Sunuwars, Newars, Thakalis, Chepangs, Brahmins, Chhetris and Thakuris. There are also occupational castes namely: Damai (tailor), Sarki (cobbler), Kami (blacksmith) and Sunar (goldsmiths).
Ethnic Diversity in the Kathmandu Valley:
Kathmandu Valley represents a cultural cauldron of the country, where, people from varied backgrounds have come together to present a melting pot. The natives of the Kathmandu Valley are the Newars. Newari culture is an integration of both Hinduism and Buddhism. The Newars of Kathmandu Valley were traders or farmers by occupation in the old days.
Terai People:
The main ethnic groups in Terai are Tharus, Darai, Kumhal, Majhi and other groups. They speak north Indian dialects like Maithili, Bhojpuri.
