Odisha, situated on the eastern coast of India, is characterized by diverse physiographic features, including coastal plains, plateaus, and mountainous regions. This diversity, coupled with varying climatic conditions, has led to the demarcation of ten distinct agro-climatic zones in the state. Understanding these zones is crucial for the OPSC exam, as it sheds light on the agricultural practices, crop suitability, and challenges faced by farmers in different regions.
Overview of Odisha’s Climate
Odisha primarily experiences a tropical monsoon climate, with distinct wet and dry seasons.
- Summer (March to June): Extremely hot and humid, especially in interior regions, with temperatures often exceeding 40∘C. Coastal areas experience moderated temperatures due to sea breezes.
- Monsoon (June to September): The southwest monsoon brings the bulk of the annual rainfall (averaging 1200-1500 mm), which is crucial for agriculture. Rainfall distribution is uneven, with higher rainfall in districts like Malkangiri and Koraput, and lower rainfall in western districts like Balangir. This season is prone to floods and cyclones.
- Post-Monsoon (October to November): A transitional period with retreating monsoon winds, often characterized by cyclonic storms originating in the Bay of Bengal.
- Winter (December to February): Mild and pleasant, with cooler temperatures in hilly areas (sometimes below 10∘C). Winter rainfall, though less frequent, is important for rabi crops.
