The monsoon is a crucial season for farmers, as southwest monsoon irrigates a large portion of the agricultural land in India. In recent decades, the monsoon has shown variability in timing, amount, and distribution of rainfall. In order to determine the sowing date, crop pattern, plan for protective irrigation, and conduct intercultural operations, it is also crucial to be aware of the onset and withdrawal of the rainy season. The analysis of weekly rainfall data reveals significant variation in the timing and duration of the monsoon across different locations. Lonavala experiences the earliest monsoon onset in week 23 (04 Jun-10 Jun), while Kasbe Digraj sees the latest onset in week 29 (16 Jul-22 Jul). Most locations, such as Gadhinglaj, Igatpuri, and Karad, experience the monsoon beginning around week 24 (11 Jun-17 Jun), with later starts in regions like Savali Vihir. Monsoon withdrawal also varies, with Savali Vihir seeing the earliest withdrawal in week 40, and Pune and Vadgaon Maval experiencing the latest in week 44. The length of the rainy season ranges from 12 weeks in Savali Vihir to 20 weeks in Mahabaleshwar, with other locations falling in between. This variability underscores the influence of local conditions on monsoon patterns and highlights the need for tailored agricultural strategies to optimize crop management and adapt to local climatic conditions. Understanding these variations is crucial for effective planning of planting schedules and irrigation practices. Hence, the present study entitled, “Onset and withdrawal of monsoon in different research stations under MPKV Rahuri jurisdiction, (Maharashtra, India)” conducted.
