climate of Tripura exhibits a strong seasonal rhythm. The State is
characterised by a warm and humid sub-tropical climate with five
distinct seasons, namely, spring, summer, monsoon, autumn and winter.
Winter starts in the month of December; it is short and followed by a
brief spell of spring. Spring starts from mid-February and continues
Winter returns if there is rain in mid-February. Summer season starts
from middle of March and reaches its peak in April-May. Pre-monsoon rain
is always experienced after jhum harvesting in the hills in March-April.
Occasionally there is no significant gap between pre-monsoon and
Relatively high temperature, occasional thunderstorms and wind
velocities characterise the summer season, which extends from March end
to mid May. The average maximum temperature is 34ºC and average minimum
temperature is 15ºC. The annual minimum and maximum ambient temperatures
recorded at Agartala Airport of the Tripura West District during 1994
are 15.9ºC and 33.4ºC respectively.
The state is a high rainfall zone with the incidence of very high
concentration of rainfall (up to 450 mm per day) in the monsoon season,
which lasts from June to September. The average annual rainfall in the
state is 2024.4 mm (50 years average). Maximum rainfall is generally
received in the months of July to September. Intermittent rainfall is
received round the year, but the pattern of rainfall throughout the year
is not homogenous.
Other Climatic Characteristics:
Humidity is generally high throughout the year. During the summer, the
humidity varies between 50% and 75% while in the southwest monsoon it is
over 80%. Due to high rainfall in the area and relatively high
temperature, humidity is also very high.
Skies are heavily clouded during the southwest monsoon season. In the
post-monsoon months cloud formation is moderate. During winter season
sky is predominantly clear from clouds and occasional light cloud
Winds are generally light except in the later half of summer and the
monsoon months when they are moderate. During summer and to a lesser
extent in the post – monsoon season, winds are south-easterly. They
gradually are back to a northerly direction in the post-monsoon and
early winter season. Thereafter, the southern-lies begin and these
become predominant in the summer.
