Latest revision as of 06:53, 6 February 2026
West Bengal has a varied climate, with tropical savannahs in the southern portions of the state, to humid subtropical areas in the north. Temperatures vary widely, and there are five distinct seasons. The area is vulnerable to heavy rainfall, monsoons, and cyclones. There are some mountains in the area which are generally cold all year round.
Seasons[edit | edit source]
There are six main seasons in West Bengal: summer (Grishma), monsoons or rainy season (Barsha), autumn (Sharat), late autumn/pre winter (Hemanta), winter (Sheet), spring (Bawshonto) .
Spring[edit | edit source]
Spring is considered the most pleasant season over the plains of West Bengal and lies from mid-February to mid-March and is also the time where Holi is celebrated. Temperatures range between 20 °C – 30 °C and no rainfall. Though occasional rain or light showers are witnessed due to Western disturbances in North India.
Summer[edit | edit source]
The summer season is observed from March to May in most of Bengal.
Temperature[edit | edit source]
In Bengal, summers can be extremely hot and have high humidity. The plains of South Bengal have a daily maximum temperature around 35–38 °C.[1][2] It can also exceed 40 °C.[3][4][5][6][7] The western highlands experience a dry summer like northern India. During the day, the temperature ranges from 38 to 42 °C, though it can reach or exceed 45 °C.[8][9][10][11][12] In summer, the plains of North Bengal are generally cooler than the west and south.[13][14][15] In this area, the daily maximum temperature varies from 26 °C to 32 °C.[16] It occasionally crosses 35 °C. The minimum temperature in summer is approximately 18–22 °C. The Darjeeling hill region is the coolest area in summer. Here, the daily highest temperature is 15–25 °C.
Rainfall[edit | edit source]
| City | Average temperature (°C) | Average Rainfall (mm) |
|---|---|---|
| Darjeeling | 13.1 | 446 |
| Siliguri | 24.2 | 447 |
| Jalpaiguri | 24.0 | 453 |
| Malda | 28.3 | 188 |
| Shantiniketan | 29.4 | 264 |
| Behrampore | 29.3 | 136 |
| Krishnagar | 29.5 | 96 |
| Asansol | 30.0 | 114 |
| Bankura | 29.9 | 146 |
| Kolkata | 29.8 | 227 |
| Digha | 28.4 | 214 |
| West Bengal | 26.9 | 248.3 |
Monsoons[edit | edit source]
Period[edit | edit source]
In mid-June or early July, the monsoon season starts.
Temperature[edit | edit source]
In most places, the temperature drops as cloud cover increases. This is less true for the mountains and the Terai Dooars plains, where temperature gradually increases until August.
The maximum temperature of South Bengal's plains and western highlands is 32 °C,[18] 31 °C in North Bengal plains and around 19–20 °C in mountains. Sometimes when the sky gets clear, the temperature rises suddenly. This is known as a monsoon break. This occurs mostly in North Bengal plains and in mountains in July and August when the temperature soars over 36 °C and 24 °C respectively.[19][20][21][22][23]
Rainfall[edit | edit source]
Most of the annual rainfall occurs during the monsoon period. Heavy rainfall above 250 cm is observed in the Darjeeling, Jalpaiguri, Alipurduar and Cooch Behar district.[24][25][26][27][28] Later, blowing westwards, the winds cause average rainfall of 125 cm in the northern plains and western plateau region.
| City | Average temperature (°C) | Average Rainfall (mm) |
|---|---|---|
| Darjeeling | 16.4 | 2796 |
| Siliguri | 28.1 | 2651 |
| Jalpaiguri | 28.0 | 2674 |
| Malda | 29.6 | 1207 |
| Shantiniketan | 29.4 | 1510 |
| Behrampore | 30.2 | 1036 |
| Krishnagar | 29.4 | 1348 |
| Asansol | 29.5 | 1140 |
| Bankura | 30.3 | 1227 |
| Kolkata | 29.6 | 1358 |
| Digha | 29.1 | 1192 |
| West Bengal | 28.1 | 1649.0 |
Autumn[edit | edit source]
Period[edit | edit source]
Autumn lasts for two months, October and November.
Temperature[edit | edit source]
In autumn, the southwest monsoon wind returns and clears the sky. So, the state gets enough sunshine to be warm in the day and releases a lot of heat to be cool at night.
At this time, a maximum temperature of 30–33 °C is felt over the plains and 17–19 °C in mountains. The minimum temperature is normally around 19–22 °C in plains and 6–11 °C in mountains.[29] Sometimes, cold waves blow over the state in autumn.[30][31][32]
Rainfall[edit | edit source]
In autumn, the southwest monsoon wind returns, and the northeast monsoon wind enters West Bengal. Due to their collision in Bay of Bengal, some cyclones are created.[33][34] The cyclones cause some rainfall in the state.
| City | Average temperature (°C) | Average Rainfall (mm) |
|---|---|---|
| Darjeeling | 13.4 | 74 |
| Siliguri | 23.2 | 181 |
| Jalpaiguri | 23.6 | 169 |
| Malda | 26.2 | 132 |
| Shantiniketan | 25.3 | 212 |
| Behrampore | 26.2 | 146 |
| Krishnagar | 26.5 | 175 |
| Asansol | 24.8 | 125 |
| Bankura | 25.9 | 94 |
| Kolkata | 26.6 | 216 |
| Digha | 25.9 | 240 |
| West Bengal | 24.3 | 160.4 |
Winter[edit | edit source]
Period[edit | edit source]
The winter season usually starts in December and ends in February.[35]
Temperature[edit | edit source]
In winter, a mild temperature is observed over the plains. The maximum temperature goes to 23–26 °C and the minimum temperature is 9–15 °C in plains of the state.
