The climate of Bangladesh
Bangladesh is a country located in Asia. The entire country has a
tropical monsoon climate (type Am according to the Köppen climate
classification). The monsoon climate in Bangladesh affects the way
people live and work here. Heavy rainfall during the wet season during
the period from May till October causes large areas of Bangladesh to
flood. Not only does all the rainwater that falls on the land end up
in Bangladesh via the river deltas; this also goes for the billions of
liters of water that fall in the Himalayas. The monsoon period is
responsible for a lot of damage and casualties on the one hand; on the
other hand it makes the land very fertile.
Climate information on cities and regions in
The climate information given on this page is only brief. Specific
information on weather and climate can be found on the pages per
region or city. The following climate information is available for
Officially the monsoon is from June till August with the months of May
and September as a transition period. During the monsoon more than 500
millimeters of rain can be recorded per month locally. Rain usually
falls in the form of showers that can last for several hours. The
biggest chance of rain is during the afternoon and the early evening.
After this skies will clear rapidly. The large amount of precipitation
in combination with temperatures between 30-37 degrees Celsius are
responsible for high humidity figures. During this period it may feel
very muggy in Bangladesh. During the summer humidity figures are well
over 80 percent; during the winter humidity figures usually are
between 70-75 percent. The rainy period ends in October. After this
the weather is very stable and mostly sunny. Especially during the
relatively cold months of November, December and January skies are
often bright blue and rain is scarce.
Where temperatures are concerned Bangladesh also has two seasons: the
slightly colder winter with maximum temperatures between 22-29 degrees
Celsius and minimum temperatures between 8-19 degrees Celsius.
Temperatures depend on your location in relation to the sea and the
height in relation to sea level. During spring temperatures rapidly
rise to 34-37 degrees Celsius. After this the monsoon starts and the
heat is being moderated. During the summer differences in temperatures
between day and night are the smallest. During the day temperatures
will be between 31-34 degrees Celsius, during the night temperatures
will drop just below 30 degrees Celsius.
The biggest natural disasters that hit Bangladesh are floods and mud
slides. These intense floods happen because Bangladesh is situated
just south of India which is one of the wettest regions in the world.
The city of Cherrapunji is situated just north of the border with
Bangladesh. About 12,000 millimeters of annual rain is recorded here
which makes it one of the wettest places on earth. The rain that falls
here all flows toward Bangladesh. Another danger is that of
hurricanes. Bangladesh is situated in a region with hurricane activity
from May till December. Sometimes a tropical storm hits Bangladesh
with all its consequences.
Throughout Bangladesh several climate zones and temperatures can
be found. The data in the table below are an average for the capital
of Dhaka and cannot be seen as an average for the entire country.

Climate tables are useful but they don’t give an overall picture of
the climate and possible weather conditions during a period of time.
How high the chances are of hot or cold weather or hurricanes can
often not be found in these tables. This is why we offer extra climate
