Description There are traditionally six seasons in the Bengali year: Summer, Rain, Autumn, Late Autumn, Winter and Spring. All the seasons of Bangladesh bear the different characteristics from one to another place. Bangladesh has been divided into seven climatic sub-regions. These seven climatic sub-regions are South-Eastern, North-Eastern, Northern part of the north region, North-western region, Western dry region, South-western region and South-central region. South-Eastern Zone This comprises the Chittagong region and a strip of country north to Comilla. The hills over a thousand feet in height. The rest of the area has the small change of temperature rarely going over a mean of 32 degree C and below a mean of 12 degree C. Rainfall is heavy usually over 254 cm. In winter dew-fall is heavy. North-Eastern Zone This includes most of the east and south Sylhet and a strip south of the Meghalaya plateau. Here mean maximum temperature is rarely above 32 degree C but mean minimum temperature is 10 degree C and below. Average humidity is even more. In this sub-region only is winter rain appreciable. Fog is very common in winter. This is the cloudiest part of Bangladesh. The higher hills and mountains of Chittagong region can be classified in this sub-region. Northern part of north region This is an area of extremes. In summer maximum temperature is well above 32 degree C. Where, as in winter the mean minimum is below 10 degree C. The summer is dry, with a scorching westerly wind, but the rainy season is very wet with 200 to 300cm rainfall. North-Western Zone Except that the extremes are less and the rainfall is lower in this sub-region is similar to northern part of north region. The lower rainfall makes this area both atmospherically and pedologically drier. Western Zone This sub-region comprises Rajshahi district and parts of the adjacent district. This is the driest area of Bangladesh with rainfall generally below 150 cm and summer humidity is less than 50%. In summer, it is the hottest and driest of all sub-regions. Means summer maximum are over 32 degree C. South-Western Zone Here the extremes of the sub-regions to the north are somewhat tempered. Rainfall is between in 152 to 175cm. Mean summer maxima are below 32 degree C. Rainfall is normally heavy. South Central Zone Rainfall is abundant, being above 190cm. The range of temperature is as can be expected much less than to the west.
