is generally predictable and pleasant. There are
four climatic seasons:
- March to May (spring),
- June to August (summer),
- September to November (autumn)
- and December to February (winter).
The monsoon is approximately
from the end of June to the middle of September.
About 80% of the rain falls during that period,
so the remainder of the year is dry. Spring and
autumn are the most pleasant seasons; winter temperatures
drop to freezing with a high level of snowfall
in the mountains. Summer and late spring temperatures
range from 28ºC (83ºF) in the hill regions
to more than 40ºC (104ºF) in the Terai.
In winter, average maximum and minimum temperatures
in the Terai range from a brisk 7ºC (45ºF)
to a mild 23ºC (74ºF). The central valleys
experience a minimum temperature often falling
bellow freezing point and a chilly 12ºC (54ºF)
maximum. Much colder temperatures prevail at higher
elevations. The Kathmandu Valley, at an altitude
of 1,310m (4,297ft), has a mild climate, ranging
from 19-27ºC (67-81ºF) in summer, and
2-20ºC (36-68ºF) in winter.
Lightweight and tropical clothes with umbrella
are advised for June to August. Between October
and March, lightweight clothes are worn in Kathmandu,
with a coat for evenings and warm clothing for
