The Eastern coast of India spreads from the Ganges Delta in the north to Kanyakumari in the south and is washed by the Bay of Bengal. It is more broad and more extensive than the west coast of India and has width that ranges from 80 to 100 km. The East coast of India is well-known for sea beaches, lagoons, and offshore bars.
The cyclonic depressions which initiate in the Andaman Sea cross the Eastern coasts of India. Due to this heavy and widespread rainfall is seen in the eastern coasts of India. This is one of the reasons for the delta region of the eastern coast to be frequently struck by cyclones. Various pressure changes are seen in the Bay of Bengal which leads to the development of cyclones. As the eastern coast of India is lined by the Bay of Bengal there is always a risk of the delta region of the eastern coast to be frequently struck by cyclones. Cyclones are witnessed in the Bay of Bengal in both the pre-monsoon and the post-monsoon period. The cyclonic winds from the other water bodies are transferred by the Bay of Bengal to the eastern coast of India due to which cyclones occur in that region. Humidity and surface sea temperatures are responsible for the formation of cyclones. The possibility of cyclone formation is high in Bay of Bengal as high average rainfall is observed over there.
Cyclones are seen in the thickly populated delta regions of the Godavari, the Kaveri and the Krishna which cause great damage to life and property. These cyclones are often proved to be destructive. In the year 2019 cyclone Amphan was seen in the region of West Bengal and Odisha.
