The best time for booking your Port Blair holiday package is during the winter season or summer season. The winters, lasting from October to February, are the peak season, perfect for water activities and sightseeing in the pleasant weather. March to May are the summer months when the temperatures are a little higher but not harsh, and sightseeing is a delight. With high underwater visibility during these months, the summers are great for snorkelling and scuba diving. While the monsoons come with great deals for a Port Blair holiday package, the chances of heavy rainfall, cyclonic weather, and strong winds can hamper your sightseeing plans.
