Nepal's weather is generally predictable and pleasant. There are four
climatic seasons: March-May (spring), June-August (summer),
September-November (autumn) and
December-February (winter). The monsoon is approximately from the end of
June to the middle of September. About 80 per cent 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
1310m (4297ft), has a mild climate, ranging from 19-27ºC (67-81ºF) in
summer, and 2-20ºC (36-68ºF) in winter.
Kathmandu In June
Average temperatures during late June and
early July range from the mid 80s to low 90s during the day to the upper
60s to mid 70s at night. Based on 4 previous
trips, I would recommend the following:
Lightweight and tropical clothes and an umbrella as rain fall can be
extremely heavy at times. Raincoats tend to be a bit uncomfortable in
Kathmandu's hot and humid weather. Men may wear shorts and T-shirts.
Ladies must be covered below the knees and must keep their shoulders
covered. Depending on the day's weather, a light jacket would be
advisable for evening. Very rainy days tend to lead to cool damp nights
that are, for some, a bit below comfort level. Sandals or quick drying
shoes are advisable, again as rain is frequent and at times heavy. No one
wants to have wet feet for days.
