Conventional travel wisdom points you to February for the calmest seas, but December is the true prize: it delivers bright tropical water with less than half the foot traffic that chokes the islands later in the dry season.
Scattered across the remote boundary where the Bay of Bengal meets the Andaman Sea, this archipelago of over two hundred islands feels genuinely untamed. Dense rainforest spills directly onto pale coral sands, and modern civilization remains a cautious guest—certain waters, like those surrounding North Sentinel Island, are strictly quarantined by maritime law to preserve the uncontacted Sentinelese people. For travelers granted access, the journey is defined by open horizons, old British naval ruins overtaken by banyan roots, and electric turquoise reefs. Yet the islands have a paradoxical calendar: the month everyone flocks here is suffocatingly hot, while the finest window to claim an empty beach slips past largely unnoticed.
Look at any standard weather chart and you will be told to wait until late winter to book your ferry. Do not listen. December is the archipelago's best-kept secret. While November's lingering squalls have cleared and the water visibility returns to shimmering clarity, the mainstream winter rush has not yet materialized.
Days in December are defined by gentle warmth and steady sunshine filtering through the sea breeze. Walking along Radhanagar Beach on Havelock Island in December means you can wander for kilometers on soft white sand without tripping over tour groups or roaring speedboat charters. The coral shallows around Elephant Beach are tranquil, and catching the inter-island catamarans from Port Blair is remarkably stress-free. There is a quiet, contemplative cadence across the islands that disappears the moment the new calendar year turns.
By January, the sea turns to glass. February follows with arguably the most pristine skies of the year, utterly bone-dry and washed clean of tropical haze. The dive sites hum with manta rays, reef sharks, and vivid shoals, while the limestone headlands of Neil Island glow beneath uninterrupted sun.
Cultural life peaks during this stretch. Port Blair fills with energy for the Island Tourism Festival in January, followed closely by the music and handicraft stalls of Subhash Mela. But you will feel the sudden weight of popularity. Ferry tickets to Neil Island and Havelock Island sell out days in advance, beachfront cottages fill up, and the tranquil sunsets at Laxmanpur Beach become shared spectacles alongside hundreds of domestic holidaymakers. February gives you flawless weather, but you will pay for it in privacy.
March begins the slow, heavy simmer of the tropical spring. By April, the Andaman climate turns oppressive, with daytime heat and thick humidity making inland walks through rainforest trails intensely draining before midday.
Curiously, April marks the absolute peak of traveler arrivals for the entire year. Domestic holiday schedules and the high-profile Beach Festival bring immense crowds to the shoreline just as the ambient conditions deteriorate. The midday sun beats down mercilessly on Corbyn's Cove and the historical open-air grounds of Ross Island. You can still find exquisite snorkeling in the morning hours before the water warms up, but staying outside through the afternoon demands constant shade, hydration, and patience with crowded ferries.
In May, the sky splits open. The southwest monsoon strikes the Andaman chain with unrelenting fury, bringing colossal rainfall and wild swells that frequently halt inter-island boat services for days at a time. Between June and September, the archipelago receives torrential downpours that drench the jungle canopy and churn the nearshore waters into murky soup.
Traveling now requires surrendering your itinerary to the weather. Snorkeling and scuba diving cease almost entirely. However, for those who seek dramatic solitude, the monsoon shows a breathtaking, primal side of the islands. August brings the spirited Monsoon Festival, where islanders embrace the storms with indoor concerts and steaming food, while September celebrates local seafood during the Food Festival. If you visit, stay rooted in Port Blair where paved roads and urban infrastructure keep you insulated from the wilder elements.
November acts as the great reset button. The ferocious monsoon downpours taper off into brief, sporadic afternoon showers, leaving the interior forests emerald green and the waterfalls running full.
The ocean begins to settle, diving operators inspect their boats, and the resorts on Havelock Island and Neil Island shake off months of salt spray and shuttered doors. Crowd levels remain exceptionally low. While you might still lose an occasional afternoon to a passing squall, November offers an enticing, freshly scrubbed preview of paradise just before the dry-season gates swing wide open.
