The mean monthly rainfall diagram for Nagpur reflects a typical Tropical Savanna (Aw) climate pattern, characterized by a distinct summer monsoon peak and dry winters. Nagpur, located in central India (Maharashtra), receives the bulk of its precipitation during the Southwest monsoon months of June to September [5]. According to meteorological data, Nagpur's rainfall peaks significantly in July and August, often exceeding 250-300 mm per month, while winter months like January and February receive negligible rainfall, typically less than 1-2 cm [4]. This sharp contrast between the heavy monsoon deluge and the arid winter season is a hallmark of the central Indian plateau's climatic regime [5]. In comparison, Allahabad and Lucknow (Upper/Middle Ganga Valley) show slightly different onset timings and lower total volumes, while Vadodara (Gujarat) exhibits a more compressed rainfall window [4].
