The Terai region extends along the southern border of Nepal, northern India, and parts of Bhutan and Bangladesh. The “arc” is the transition between the plains and the mighty Himalayas. Its geography consists of alluvial plains formed by sediment deposits from the Himalayas, making the soil highly fertile. The climate of the Terai varies from subtropical to tropical, with hot and humid summers and relatively cold winters. The region receives higher levels of rainfall compared to the surrounding areas.

The monsoon season brings heavy rainfall to the Terai, as moist air from the Indian Ocean moves northward and hits the Himalayan foothills. This period can lead to flooding in some areas, as the region receives a substantial amount of rain. The temperatures remain warm during this time, and humidity levels are high. While the monsoon is essential for agriculture, excessive rainfall can also lead to various challenges, such as landslides and waterlogging.
Autumn is another favorable season for tourists in the Terai. After the monsoon, the weather starts to cool down, and the skies become clearer. The region’s lush landscapes, combined with the view of the nearby Himalayan peaks, make this an ideal time to explore the area.
