| Region | Rainy Season Window | Characteristics | | :--- | :--- | :--- | | | June 1 – Mid-September | The first to get rain; heavy and intense. Good for Ayurveda retreats, but bad for beach holidays. | | Mumbai & West Coast | June 10 – Late September | Extremely heavy rainfall. The city often floods, but the surrounding hills (like Lonavala) are lush and green. | | Delhi & North India | Late June – Mid-September | Humid heat followed by dramatic thunderstorms. The rain provides relief from the scorching summer heat. | | Northeast India | Early June – October | Receives the highest rainfall in the world (e.g., Cherrapunji). Not recommended for travel due to landslides and floods. | | Tamil Nadu (East Coast) | October – December | The Exception. This region does not get the main monsoon. It gets its rain during the "Retreating Monsoon" (Northeast Monsoon) in winter. | | Ladakh & Himalayas | Varies | Ladakh is a high-altitude desert and gets very little rain (good to visit in July/Aug). However, lower Himalayan regions (Himachal/Uttarakhand) have high risks of landslides. |
