Explanation

The Andaman and Nicobar Islands are an archipelago located in the Bay of Bengal, characterized by an equatorial climate due to their proximity to the equator and the surrounding maritime influence.

  • Statement 1 is Correct: The islands experience a humid, tropical coastal climate. Being situated between 6°N and 14°N latitude, the region maintains high temperatures throughout the year with minimal seasonal variation and high humidity levels typical of tropical maritime environments.
  • Statement 2 is Correct: The islands are unique in receiving rainfall from both the South-west monsoon (June to September) and the North-east monsoon (October to December). Due to their location in the Bay of Bengal, they are the first Indian territory to receive the South-west monsoon winds.
  • Statement 3 is Incorrect: The period between December and May is generally considered the relatively drier season. The maximum precipitation occurs during the monsoon months, specifically from May/June to November. The peak rainfall period is associated with the South-west monsoon and the retreating monsoon/cyclonic activity in the Bay of Bengal.

Key Takeaway: The Andaman and Nicobar Islands feature a tropical maritime climate characterized by high humidity and a bimodal rainfall pattern derived from both the South-west and North-east monsoons.
