Why only rainfall comes in June to September in India only?

In India, the rainfall from June to September is primarily due to the southwest monsoon, which is driven by the differential heating of land and sea. During this period, the Indian subcontinent heats up, creating low pressure that attracts moisture-laden winds from the Indian ocean. These winds bring significant rainfall, especially to the western coast and the northeastern regions. The monsoon's timing and intensity are influenced by various factors, including the Indian Ocean Dipole and the El Niño phenomenon.
