The climate of Arunachal Pradesh varies with elevation. Areas with very high elevation in the Upper Himalayas near the Tibetan border enjoy an alpine or Tundra climate. Below the Upper Himalayas come the Middle Himalayas, where people experience a temperate climate. Fruits like apples, oranges, etc are grown. Areas at the sub-Himalayan and sea-level elevation experience a humid sub-tropical climate, with hot summers and mild winters.
