The monsoon seasons bring heavy rainfall, which can lead to flooding in low-lying areas and disrupt outdoor activities such as hiking and sightseeing. Kerala and Goa experience significant rainfall during the southwest monsoon, while Tamil Nadu faces similar conditions during the northeast monsoon. Travellers may encounter challenges such as waterlogged roads and altered itineraries. However, the rains also rejuvenate landscapes, making them ideal for nature enthusiasts. The dry season from December to March is less risky, with comfortable weather and fewer disruptions.
