This is the easiest time to cruise the Andaman waters: skies are mostly clear, seas are calm, and every operator runs on schedule. Book ferries 4-6 weeks ahead — capacity tightens fast over Christmas, New Year, and Pongal.
The Port Blair (Sri Vijaya Puram) → Neil Island (Shaheed Dweep) ferry runs daily, with the Makruzz, Green Ocean, Nautika, and Sealink fleets covering the route between them. Tickets sell out fastest 2-4 weeks before departure in peak months, and ferries occasionally re-schedule due to sea state. Magical Andaman shows live availability across every operator, so you can compare cruise time and fare in one place.
October is the most popular month for ferry travel. Book early. Sunrise on Radhanagar Beach (Havelock) and the Cellular Jail Light & Sound (Port Blair) are both worth building into the itinerary.
