Best Time to Visit Port Blair: Month-by-Month Guide | Weather, Activities & Tips
Quick Answer
The best time to visit Port Blair is October to February, the northeast monsoon keeps the Bay of Bengal calm, skies are clear, temperatures stay at 24–30°C, and all water activities (diving, snorkelling, sea kayaking, island ferries) operate fully. November and December are the sweet spot: post-monsoon freshness, near-perfect sea conditions, and fewer tourists than peak January. Avoid May to September if you want beach and water activity, the southwest monsoon brings rough seas, ferry cancellations, and occasional cyclone risk. Budget travellers can visit March–April (warmer but still dry, lower prices). |

Season-by-Season Guide
October to February — The Best Time to Visit Port Blair
This is Port Blair's prime season in every way. The northeast monsoon brings dry weather and calm seas to the Bay of Bengal, creating ideal conditions for all water-based activities. The underwater visibility reaches 20–30 metres at top dive sites — North Bay Island, Jolly Buoy Island, and Elephant Beach at Havelock. Ferries to Havelock Island (Neil Island, Little Andaman) run on full schedule.
October marks the transition from monsoon — the seas calm progressively through the month, and by late October all inter-island ferries are reliably operating. Wildlife activity is high: nesting turtles (Olive Ridley) are active on Cuthbert Bay from October.
November and December are the finest months — perfect sea conditions, clear skies, temperatures in the low-to-mid 20s at night, and a festive energy from the Island Tourism Festival (usually November–December, Port Blair). Hotel prices are 20–30% lower than January peak.
January and February are peak season — maximum tourist activity, highest hotel prices (book 4–6 weeks ahead), and the clearest skies of the year. February has the best underwater visibility of any month and is the preferred month for divers and snorkellers.
What to book in advance: The government ferry to Havelock Island (MV Makruzz or Green Ocean vessels) fills rapidly in December–February — book online at andaman.gov.in or directferries.in 2–3 weeks ahead.
March to April — Shoulder Season and Budget Option
March and April are Port Blair's shoulder season — warmer (up to 34°C in April), drier, and with manageable sea conditions for most water activities. Tourist numbers drop significantly from January peak, hotel prices fall 15–25%, and the islands feel noticeably quieter. April is very hot — plan water activities for early morning and retreat to shade by midday.
Best for: Budget travellers who want a quieter island experience; travellers whose dates don't allow a winter visit; those specifically interested in Cellular Jail and heritage rather than water sports.
May to September — Monsoon Season
The southwest monsoon arrives in May and dominates through September — bringing heavy rainfall (up to 400mm in July), rough seas, frequent ferry cancellations, and occasional cyclone warnings. Most outer island ferry services (to Havelock, Neil, Baratang) are suspended or severely disrupted during this period.
What still works: Port Blair's heritage sites (Cellular Jail, Anthropological Museum, Ross Island, Samudrika Museum) are fully accessible. The city of Port Blair itself is manageable between rain bursts. Corbyn's Cove beach is swimmable on calmer days.
Budget advantage: Hotel rates drop 30–50% during monsoon; some resorts offer best-available packages to fill rooms.
What to avoid: Planning any beach holiday, snorkelling trip, or inter-island excursion during July–August. Ferry cancellations are frequent and unpredictable; do not plan tight connections.
Key Port Blair Attractions and Best Time for Each
Cellular Jail (Kala Pani) — Year-Round
Built by the British between 1896 and 1906 to imprison Indian independence fighters, the Cellular Jail is Port Blair's most historically significant landmark. The seven-wing radial design housed 698 individual cells, each too small for a prisoner to lie fully extended. Prisoners included notable freedom fighters — Veer Damodar Savarkar, Batukeshwar Dutt, and Yogendra Shukla — who were subjected to hard labour, solitary confinement, and documented torture.
The jail's architecture — with its central guard tower providing sightlines down all seven wings simultaneously — was designed to prevent communication between prisoners. The structure now operates as a National Memorial.
- Entry: ₹30 (Indians), ₹10 (children)
- Timings: 9 AM – 1 PM, 1:30 PM – 5 PM; closed Monday and national holidays
- Sound & Light Show: Tuesday, Wednesday, Friday, Saturday — Hindi: 7:30 PM; English: 8:45 PM. Entry ₹50 (Indians), ₹200 (foreigners). The show reconstructs the stories of imprisoned freedom fighters with narration, lighting, and period music — genuinely moving and strongly recommended.
- Best time: Year-round; combine with the Sound & Light Show for an evening visit
North Bay Island — Snorkelling and Coral Gardens (October–April)
Located 20 minutes by boat from the Aberdeen Jetty, North Bay Island is Port Blair's premier snorkelling site — a shallow coral reef with excellent visibility (15–25m in season), abundant reef fish, and the distinctive lighthouse that appeared on India's ₹20 note. Glass-bottom boat rides are available for non-swimmers.
- Ferry from Aberdeen Jetty: ₹350–₹500 per person return (government ferry)
- Best time: November to February for clearest visibility
- Tip: Government ferries offer the best value; private tour operators charge 2–3x the price for the same experience
Ross Island (Netaji Subhas Chandra Bose Island) — Year-Round
Ross Island, a 15-minute ferry from Aberdeen Jetty, served as the administrative headquarters of the British in the Andamans — housing the Chief Commissioner's residence, church, ballroom, tennis courts, and a swimming pool. After the British departure in 1942 and subsequent Japanese occupation, the island was abandoned. Today the ruins are consumed by enormous banyan tree roots — walls split by roots, buildings open to the sky, all entwined in tropical vegetation. Deer, peacocks, and tropical birds roam freely.
- Ferry: ₹50 return (government ferry from Phoenix Jetty)
- Entry: ₹50 (Indians), ₹200 (foreigners)
- Timings: 9 AM – 5 PM (closed Wednesday)
- Best time: Year-round; morning light (9–11 AM) produces the best photographs of roots through ruins
Havelock Island (Swaraj Dweep) — October to April Only
Havelock Island, 57 km from Port Blair, contains Radhanagar Beach — rated Asia's best beach by Time Magazine in 2004. The beach is 2 km of white sand facing the Andaman Sea, with forest behind and the clearest water in the Andamans. Havelock also has the best diving infrastructure in the archipelago — Elephant Beach dive sites, Lighthouse Reef, and MacroMania.
- Ferry from Port Blair: 90 minutes by government ferry (₹250–₹350); 60 minutes by private catamaran (₹800–₹1,000)
- Best time: November to February for diving and beaches; October is fine for beaches
- Important: Ferry services are significantly reduced or cancelled during monsoon (June–September) — do not plan Havelock during this period
Baratang Island — October to April
Baratang, 100 km north of Port Blair by road and boat, is famous for its limestone caves and mud volcanoes (one of only a handful of active mud volcanoes in India). Access involves driving through the Jarawa Tribal Reserve on the Andaman Trunk Road — see the critical guidance below.
- Limestone caves entry: ₹40; guided boat trip essential (₹150–₹200 per person)
- Mud volcano: Free; 30 min walk from the boat landing
- Getting there: By private car/taxi via Andaman Trunk Road (3 hours from Port Blair) — must complete in a police convoy; 6 AM departure mandatory from Jirkatang checkpost
Jarawa Tribe Restricted Area — Critical Rules for All Visitors
The Jarawa Tribe (Jarawas) are an indigenous Andamanese people who lived in complete isolation from the outside world until the late 1990s. They have no immunity to common diseases (influenza, measles, or chickenpox could be fatal to them), and contact with the outside world remains carefully managed under the Andaman and Nicobar Islands Protection of Aboriginal Tribes Regulations.
Rules that apply to ALL visitors on the Andaman Trunk Road (Baratang route):
- Stopping vehicles on the Andaman Trunk Road is strictly prohibited — violators face fines and arrest
- Photography of Jarawa people is prohibited — this is a legal requirement, not a guideline
- Distributing food, gifts, or any items to Jarawa people is prohibited — this is the most frequently violated rule and is considered a serious offence
- Vehicles must travel in a police-escorted convoy; stopping for any reason other than a police checkpoint is illegal
These regulations exist to protect the Jarawa people's health, autonomy, and right to self-determination. The Andaman Administration actively enforces these rules; violations result in immediate removal from the route and potential prosecution.

- Recommended for: Those who specifically want the sea journey experience; not recommended as primary transport for most travellers
Practical Tips
Permits: Indian nationals do not need permits for most of the Andamans. Foreigners require a Restricted Area Permit (RAP) — issued free of charge on arrival at Port Blair Airport or can be obtained in advance from Indian Embassies. RAP is required for most islands including Havelock and Neil. Restricted areas (near tribal reserves) require additional Inner Line Permits.
Currency: ATMs are available in Port Blair city. Carry adequate cash for outer islands — ATMs on Havelock are limited and frequently out of cash in peak season.
Mobile connectivity: BSNL and Airtel have limited coverage in Port Blair. Other networks have no coverage in the Andamans. BSNL SIM works on most islands; Airtel works in Port Blair and Havelock only.
Accommodation: Book in advance for November–February, especially on Havelock. Port Blair has options from ₹800/night (budget) to ₹8,000/night (resort). Havelock resorts: ₹2,000–₹15,000/night.
