India, in general has a hot tropical
climate with a wide range of climatic factors
that it's impossible to pin down the best time
to visit weather wise with any certainty. Broadly
speaking October to March tend to be the most
pleasant months over much of the country. In the
far south, the monsoonal weather pattern tends
to make Jan to Sept more pleasant, while Sikkim
and the areas of north eastern India tend to be
more palatable between March and August, and Kashmir
and the mountainous regions of Himachal Pradesh
are at their most accessible between May and September.
The deserts of Rajasthan and the north western
Indian Himalayan region are at their best during
the monsoon.
Western
Himalayas: Srinagar is best from March to
October; July to August can be unpleasant; cold
and damp in winter. Simla is higher and therefore
colder in winter. Places like Pahalgam, Gulmarg
and Manali are usually under several feet of snow
(December to March) and temperatures in Ladakh
can be extremely cold. The road to Leh is open
from June to October.
Required
clothing: Light- to mediumweights are advised from
March to October, with warmer wear for winter. Weather
can change rapidly in the mountains and therefore
it is important to be suitably equipped. Waterproofing
is advisable.
Northern
Plains: Extreme climate, warm inland from April
to mid-June falling to almost freezing at night
in winter, between November and February. Summers
are hot with monsoons between June and September.
Required clothing: Lightweight cottons and linens
in summer with warmer clothes in winter and on cooler
evenings. Waterproofing is essential during monsoons.
Central
India: Madhya Pradesh State escapes the very
worst of the hot season, but monsoons are heavy
between July and September. Temperatures fall at
night in winter.
Required clothing: Lightweights are worn most of
the year with warmer clothes during evenings, particularly
in winter. Waterproofed clothing is advised during
monsoon rains.
Western
India: November to February is most comfortable,
although evenings can be fairly cold. Summers can
be extremely hot with monsoon rainfall between mid-June
and mid-September.
Required clothing: Lightweight cottons and linens
are worn most of the year with warmer clothes for
cooler winters, and waterproofing is essential during
the monsoon.
Southwest:
The most pleasant weather is from November to March.
Monsoon rains fall between late April and July.
Summer temperatures are not as high as Northern
India, although humidity is extreme. There are cooling
breezes on the coast. Inland, Mysore and Bijapur
have pleasant climates with relatively low rainfall.
Required clothing: Lightweights are worn all year
with warmer clothes for cooler evenings, particularly
in winter. Waterproofing is advised during the monsoon.
Southeast:
Tamil Nadu experiences a northeast monsoon between
October and December and temperatures and humidity
are high all year. Hills can be cold in winter.
Hyderabad is hot, but less humid in summer and much
cooler in winter.

Waterproofing is necessary during the monsoon. Warmer

driest and most pleasant periods. The rest of the
year has extremely heavy monsoon rainfall and it
is recommended that the area is avoided.

essential in monsoons, usually from mid-June to
mid-October. Warmer clothes are useful for cooler
evenings.
