Heavy rainfall during the monsoon season (June–September) is a frequent cause of school closures in states like Assam, Kerala, and Maharashtra. Cyclones, which typically occur between April–June and October–December, can also lead to widespread disruptions, particularly in coastal regions like Odisha and West Bengal. Flooding and landslides in hilly areas such as Uttarakhand and Himachal Pradesh may result in temporary school shutdowns.
