Pleasant sub-alpine climate prevails in the hilly region of
Assam. The plains however experience tropical
climate making them uncomfortably humid especially during the rainy
seasons.
Winter sets in from around the end of the month of October and lasts till
the end of February. The temperature drops to a minimum of 6 to 8 o
Celcius, the nights and early mornings are foggy, and rain is scanty.
Summer arrives in the middle of May accompanied by high humidity and
rainfall. The temperature reaches a maximum of 35 to 38 o Celcius. The
frequent rains however serve to push the mercury down.
The Moonsoons blow full blast during the month of June. Thunderstorms
known as "Bordoichilla" are a frequent occurrence during the
afternoons. Spring and Autumn with moderate temperatures and modest
rainfall are the best seasons.
Assam falls in a zone prone to earthquakes. Though
mild tremors are familiar to the region, high-intensity earthquakes are
rather infrequent.
