Andaman & Nicobar Islands experience moderate weather almost throughout the year, but the best time to visit Andaman & Nicobar Islands is between October and May which covers the winter and the summer season. The weather stays clear and quite pleasant but humid. The temperature varies depending on the season, but it is good for sightseeing, beach exploration and water sports. Monsoons are not always recommended as the waves could be unpredictable and specific regions also receive heavy downpours.
Andaman & Nicobar Islands because of its location is a preferred destination throughout the year as the temperature remains same throughout the year. thanks
