Why is it so hot in the terai region?

The Terai region experiences high temperatures primarily due to its geographical location and climate characteristics. Situated at the foothills of the Himalayas, it has a subtropical climate, characterized by hot summers and mild winters. The region's flat topography and dense vegetation contribute to heat retention, while the seasonal monsoon brings humidity, further intensifying the perceived heat. Additionally, the proximity to the Indian plains influences the weather patterns, leading to elevated temperatures during the summer months.
