Quick Reference: Best Time to Visit Andaman Nicobar Island

Planning a trip to one of India’s most stunning island destinations? Here is a handy snapshot of everything you need to know before booking your flights and island permits.

Best Time to Visit Andaman Nicobar Island

The best time to visit Andaman Nicobar Island is from October to May. The islands experience a tropical climate with two distinct monsoon periods, and the dry season from October through May offers the calmest seas, the clearest underwater visibility, and the best conditions for every activity the archipelago is known for.

October to May: Best Season Overall

October through May is the full open season for the Andaman and Nicobar Islands and covers the widest range of weather conditions within the recommended travel window. The sea transitions from post-monsoon recovery in October to peak calm in December through February, before warming gently toward May.

October and November mark the tail end of the northeast monsoon, with occasional showers but significantly improving sea conditions compared to the peak monsoon months. The islands begin to open up in October, boats resume regular inter-island services, and the tourist season kicks into gear from mid-October onward. The landscape is lush and vibrantly green from the monsoon rains, and the beaches are largely uncrowded in this early part of the season.

December to February is the single best window within the best time to visit Andaman Nicobar Island calendar. Temperatures sit comfortably between 20°C and 30°C, humidity is at its lowest, the sea is exceptionally calm, and underwater visibility for snorkelling and scuba diving reaches up to 20 to 30 metres in the best spots around Havelock and Neil islands. This is peak tourist season, and for good reason. Every island activity, from sea walking and glass-bottom boat rides to kayaking and jungle treks on Baratang, is available and at its best during these three months.

March and April see temperatures rise to between 28°C and 34°C, but the sea remains calm and diving conditions stay excellent through April. These months offer a good balance of warm beach weather, lower hotel rates compared to December and January, and manageable crowds. Underwater visibility remains strong, making March and April the best months for dedicated scuba divers and snorkellers who want good conditions without the peak-season pricing.

May marks the last comfortable month before the southwest monsoon arrives. The heat is at its peak, with temperatures touching 34°C to 35°C, and the sea begins to show signs of pre-monsoon choppiness from mid-May onward. However, May is still a viable travel month for those who can handle the heat and want to catch the tail end of the open season at lower rates.

June to September: Monsoon

The southwest monsoon arrives in the Andaman Islands typically by late May or early June and dominates the weather through September. This is the most dramatic season on the islands, with heavy rainfall, rough seas, and strong winds. Most inter-island ferry services are suspended or severely reduced during peak monsoon weeks, and water activities including scuba diving, snorkelling, and sea walking are largely unavailable.

The landscape during the monsoon is extraordinarily lush, and the islands take on a wild, primeval beauty that is unlike anything in the dry season. However, travel during July and August is not recommended for most visitors, as sea conditions are unpredictable and ferry disruptions can leave travellers stranded on islands for days at a time.

Budget travellers who are flexible with their plans and comfortable with the monsoon conditions can find very low hotel rates and near-complete solitude on the beaches during June and September. The shoulder months of early June and late September are more manageable than the mid-monsoon peak.

About Andaman and Nicobar Islands: More Than Just Beaches

The Andaman and Nicobar Islands offer layers of experience that go far beyond their famous beaches. Port Blair, the capital and main entry point, is home to the Cellular Jail, a deeply moving colonial-era prison used by the British to exile Indian independence fighters. The jail’s evening Sound and Light show is one of the most compelling heritage experiences in India and is essential for every first-time visitor.

Havelock Island (officially Swaraj Dweep) is the most visited island in the archipelago and home to Radhanagar Beach, consistently ranked among Asia’s finest beaches. Beyond the beach, Havelock offers excellent scuba diving at sites including Elephant Beach, Jackson’s Bar, and the wreck of the MV Jahangir. Our guide on places to visit in Andaman in 7 days covers Havelock and the full 7-day island circuit in detail, including the best diving spots, ferry timings, and day trip options.

Neil Island (officially Shaheed Dweep) is the quieter, more laid-back alternative to Havelock, known for its natural rock formations, coral gardens, and unhurried pace. It pairs naturally with Havelock on a 3-day island mini-circuit. Our guide on places to visit in Andaman in 3 days covers the best short-trip itinerary for time-limited travellers.

Baratang Island is one of the most unusual stops in the archipelago, offering limestone caves, mud volcanoes, and mangrove creek boat rides through dense forest. It is accessible from Port Blair by road and boat and makes a rewarding full-day excursion for those staying in the capital.

The Andaman and Nicobar Islands sit naturally alongside India’s other great coastal destinations for travellers building a broader beach itinerary. For those comparing island and coastal options across India, our guides on hidden places in Goa and hidden places in Pondicherry cover two of the country’s most popular coastal alternatives in detail.

How to Reach Andaman Nicobar Island?

All commercial travel to the Andaman and Nicobar Islands goes through Port Blair, the capital and the only point of entry for tourists. There are two ways to reach Port Blair: by air or by ship from the Indian mainland.

How to Reach Andaman Nicobar Island by Air?

Veer Savarkar International Airport in Port Blair has direct flights from Chennai, Kolkata, Delhi, Mumbai, Bengaluru, and Hyderabad. Flight duration from Chennai is approximately 2 hours and from Kolkata approximately 2.5 hours. Flying is the most practical and time-efficient option for most travellers. Book flights well in advance for the December to February peak season, as seats on popular routes fill up quickly and fares rise sharply closer to travel dates.

How to Reach Andaman Nicobar Island by Ship?

Passenger ships operated by the Shipping Corporation of India connect Port Blair to Chennai (approximately 60 to 65 hours), Kolkata (approximately 56 to 60 hours), and Visakhapatnam (approximately 55 to 60 hours). Ships depart on irregular schedules and berth bookings must be made well in advance through the SCI website or Port Blair booking offices. The ship journey is a unique experience in itself, passing through open ocean with potential sightings of dolphins, flying fish, and seabirds, but it requires significant time and flexibility.

How to Reach Andaman Nicobar Island by Road?

There is no road connection between the Indian mainland and the Andaman and Nicobar Islands. All inter-island travel within the archipelago is by government and private ferries, speedboats, and in some cases helicopter services operated by Pawan Hans between Port Blair and select islands.

Nearby Places to Visit

The Andaman and Nicobar Islands offer a self-contained travel universe, with each island adding a distinct character to the overall experience.

• Radhanagar Beach, Havelock Island: Consistently ranked among Asia’s best beaches, Radhanagar is a long arc of white sand backed by tropical forest on the western shore of Havelock. Sunset here is one of the most photographed moments in the entire archipelago.
• Elephant Beach, Havelock Island: The top snorkelling and water sports spot in Havelock, accessible by a 30-minute boat ride or a forest trek from the main jetty. Coral cover is excellent and the shallow reef makes it ideal for beginners.
• Neil Island (Shaheed Dweep): A quieter, more intimate island than Havelock, Neil is known for its natural rock arch at Laxmanpur Beach, clean coral gardens, and peaceful village atmosphere. It is a 1.5 to 2 hour ferry ride from Havelock.
• Baratang Island: Famous for its limestone caves, mud volcanoes, and mangrove creek journey, Baratang is approximately 100 km north of Port Blair and accessed by a combination of road and boat. The mangrove boat ride through dense forest is one of the most atmospheric experiences in the islands.
• Ross Island (Netaji Subhas Chandra Bose Island): A short 15-minute ferry ride from Port Blair, Ross Island was the former British administrative headquarters for the Andaman Islands and is now a beautiful ruin of colonial-era buildings overtaken by jungle and inhabited by spotted deer. An essential half-day trip from Port Blair.
• North Bay Island: Located near Ross Island and easily combined as a day trip from Port Blair, North Bay is the most accessible spot for glass-bottom boat rides, sea walking, and introductory snorkelling for first-time visitors.

Essential Tips for Visiting Andaman Nicobar Island

A little advance planning makes a significant difference in the Andaman Islands, where ferry timings, permit requirements, and accommodation availability can all affect the shape of your trip.

• Book flights and accommodation well in advance for the December to February peak season. Port Blair hotels and Havelock resorts fill up fast, and flight fares double or triple as the season peaks around Christmas and New Year.
• Ferry bookings between islands should be made in advance, particularly for the Port Blair to Havelock and Havelock to Neil routes. The Makruzz and Green Ocean speedboats are the most comfortable options. Book online through their official websites before arriving.
• The Nicobar Islands are a Restricted Area and require a separate Restricted Area Permit for Indian nationals. The Andaman Islands (Port Blair, Havelock, Neil, Baratang) do not require any special permit for Indian citizens.
• Foreign nationals require a Restricted Area Permit to visit the Andaman Islands, which is issued free of charge on arrival at Port Blair airport for citizens of most countries. Check current permit requirements before travelling as these regulations can change.
• Carry waterproof bags or dry bags for all ferry journeys. Sea spray on open deck boats can soak bags and electronics on rougher days, even within the October to May travel window.
• Scuba diving is the single most popular activity in the islands. Reputable operators include Barefoot Scuba, Lacadives, and Dive India on Havelock. Book dive slots in advance for January and February as popular sites fill up quickly.
• The Cellular Jail Sound and Light Show in Port Blair runs on select evenings and requires advance ticket booking during peak season. Check the schedule and book on arrival in Port Blair.
• Carry sufficient cash from the mainland. ATMs in Port Blair are well stocked, but ATMs on Havelock and Neil islands have limited cash and can run out during busy periods.
• Mobile connectivity on Port Blair and Havelock is reasonable with BSNL and Jio. Neil Island connectivity is patchier. Remote islands have no mobile network. Download offline maps and carry emergency contacts before island hopping.
• Respect the marine environment at all times. Do not touch or stand on coral reefs, avoid single-use plastics on the islands, and follow the guidelines of your diving and snorkelling operators on reef etiquette.

Conclusion

The Andaman and Nicobar Islands are among India’s most extraordinary travel destinations, combining world-class beaches and diving with colonial history, tribal heritage, and tropical wilderness in a setting that feels genuinely remote from the mainland.

October to May is the best time to visit Andaman Nicobar Island for the full range of experiences the archipelago offers, with December to February being the most rewarding window for first-time visitors and March to April offering excellent conditions with fewer crowds.
