Finding the months when inbound tourist traffic from India’s top 10 source nations is either at its highest (peak) or lowest (lean) is known as “lean and peak month” for the top 10 source countries for foreign tourist arrivals (FTAs). For instance, when the weather is nice, visitors from colder places like the US, Canada, or Europe frequently travel to India in the winter (October to March). In contrast, arrivals may decline during the summer and monsoon seasons. On the other hand, nations like Bangladesh or Sri Lanka that have cultural or religious ties to India might exhibit more consistent patterns of annual visitor numbers. Seasonality, holidays, cultural events, visa simplification, and bilateral travel agreements are some of the elements that affect these lean and peak tendencies, which differ by source nation.

For tourist planning, marketing, and infrastructure management, it is essential to examine lean and peak months for FTAs from the top ten source nations. It assists companies and tourism authorities in managing resources, forecasting demand, and creating focused advertising campaigns that complement seasonal travel trends. Hotels, tour companies, and airlines can modify their service offers and pricing policies accordingly. Additionally, by identifying slow months, officials can implement off-season incentives to keep tourists coming and boost local economies all year round.
