Andaman Islands Maritime Transit Data Reveals 75 Percent Drop in Monsoon Ferry Operations Across Major Inter-Island Routes

Maritime transit analysis covering 34,868 confirmed ferry sailings across the Andaman Islands indicates a drastic reduction in inter-island passenger vessel availability, dropping from a peak-season monthly average of 2,837 legs down to just 717 monthly legs during the monsoon period.

Seasonal Andaman Maritime Operational Capacity Shifts

A comprehensive study examining 34,868 confirmed ferry legs operated between June 2025 and July 2026 highlights an extreme seasonal contraction in maritime transport services across the Andaman archipelago. Inter-island vessel traffic experiences severe fluctuation between the off-peak monsoon period (June to September) and the high-demand peak travel season (October to February).

During the monsoon months from June through September, the regional transit network recorded a monthly average of only 717 confirmed ferry legs. In contrast, peak season operations between October and February expanded to a monthly average of 2,837 confirmed ferry legs, representing a nearly 75 percent decline in overall vessel deployment during the rainy season.

ANDAMAN FERRY SEASONAL CAPACITY CONTRACTION

Column 1
Peak Season (Oct–Feb Average): [====================================] 2,837 Legs
Monsoon Season (Jun–Sep Average): [========] 717 Legs (-74.7%)

The operational reduction is most stark when examining individual months. July recorded only 8% of the ferry-leg volume available in December, pointing to a severe winter-to-summer operational swing driven by sea conditions and reduced passenger volume.

However, network contraction is not uniform across all sectors. Data maintained by transit booking platform BookYourFerry indicates that route resilience varies significantly:

• Havelock–Neil Sector: Retained only 19% of its peak-season ferry volume during the monsoon period.
• Havelock–Port Blair Sector: Maintained 43% of its peak-season vessel capacity during the monsoon months.

These sector-level variations demonstrate that connectivity between major hubs such as Port Blair and Havelock Island remains relatively prioritized, whereas secondary feeder routes experience significant schedule rollbacks.

Shift in Passenger Booking Windows and Sector Patterns

An evaluation of 3,265 booked ferry sectors compiled between April and July 2026 shows clear changes in how travelers reserve tickets as seasonal service frequencies adjust. Across the entire dataset, the overall median booking window stood at four days before departure.

PASSENGER TICKET RESERVATION TIMING DISTRIBUTION

Column 1
Last-Minute Booking (<48 Hours): [==================] 42%
Standard Advance (2 to 13 Days): [================] 36%
Early Reservations (>=14 Days): [==========] 22%

Despite the short median lead time, 22% of travellers secured their ferry tickets two or more weeks in advance. Concurrently, short-term reservations accelerated sharply: 42% of ferry seats were reserved within 48 hours of departure.

As vessel schedules scaled back entering the monsoon season, last-minute booking patterns grew more pronounced. The share of reservations made within 48 hours of departure rose from 38% in April to 48% in June.

Route specifics also directly shape advance planning behavior:

• Havelock–Neil Sector: Passengers booked their sailings a median of six days prior to departure, reflecting tighter capacity constraints on smaller catamarans and reduced schedule frequency.
• Port Blair–Havelock Sector: Passengers recorded a median booking window of three days before departure, supported by higher vessel frequency and larger capacity deployment by private operators including Makruzz, Nautika, Green Ocean, and ITT Majestic.

Vivek Lall, Founder of BookYourFerry, observed: "The Andaman Islands offer a distinctly seasonal travel experience, and ferry connectivity is an important part of that journey. What our data shows is that travellers are adapting their booking behaviour to these seasonal patterns. Looking at individual routes, rather than treating the islands as one uniform network, can help travellers plan their journeys more effectively."

Andaman Island Ferry Operational & Booking Metrics

The table below synthesizes the maritime operational metrics, route-specific capacity retention rates, and booking lead-time distributions across the Andaman inter-island ferry network:

Operational Metric / Route Sector	Peak Season (Oct–Feb)	Monsoon Season (Jun–Sep)	Seasonal Variance & Retention	Median Reservation Lead Time
Network-Wide Monthly Volume	2,837 average legs	717 average legs	74.7% operational reduction	4 days (overall network median)
Single-Month Volume Extremes	December (Baseline 100%)	July (8% of Dec volume)	92% single-month capacity drop	48% booked <48 hrs in June
Havelock–Port Blair Link	100% full deployment	43% capacity retained	Highest monsoon sector resilience	3 days before departure
Havelock–Neil Link	100% full deployment	19% capacity retained	Severe monsoon reduction	6 days before departure
Short-Term Advance Booking	38% reserved <48 hrs (Apr)	48% reserved <48 hrs (Jun)	10 percentage point last-minute shift	Sector dependent
Long-Lead Reservations	22% reserved >=14 days	22% reserved >=14 days	Consistent baseline early planner share	Applicable across all major links

Official regulatory coordination by the Directorate of Shipping Services (DSS) and public safety directives from the Andaman & Nicobar Administration govern monsoon sailing approvals to ensure vessel stability in heavy sea states.

Traveler Logistics & Inter-Island Connection Guide

Navigating inter-island ferry transfers across the Andaman Sea requires strategic planning, particularly when managing air-to-sea transit connections through Port Blair.

PORT BLAIR TRANSIT & FERRY CONNECTION FLOW

[ Flight Arrival ] ---> [ Baggage & Customs ] ---> [ Jetty Transfer ]
(Veer Savarkar Airport) (30-45 Mins) (20-30 Mins to Haddo Jetty)
v
[ Pre-Boarding & Security ]
(60 Mins Before Departure)
v
[ Inter-Island Vessel Boarding ]

Air-to-Sea Layover Windows at Port Blair

Passengers arriving at Veer Savarkar International Airport (IXZ) in Port Blair must factor in a minimum 3 to 4 hour layover window before scheduled ferry departures from Haddo Jetty or Phoenix Bay Jetty. Flights arriving after 12:00 PM local time carry a high risk of missing the final afternoon high-speed catamaran sailings to Havelock Island, which typically depart between 1:30 PM and 2:00 PM.

Digital Transit and Jetty Security Clearance

While air travelers arriving in India utilize the Digi Yatra facial recognition biometric platform at domestic airport terminals, maritime passenger terminals in Port Blair rely on manual manifest verification:

1. Identity Verification: All Indian nationals must present original government-issued photo ID (Aadhaar, Passport, or Voter ID). Foreign nationals must present a valid passport and Indian visa.
2. Passenger Manifest Registration: Ticket vouchers must match government identification exactly. Discrepancies lead to immediate boarding denial at jetty security gates.
3. Physical Baggage Inspection: Heavy luggage must be checked at the vessel luggage deck 45 minutes prior to departure.

Sector-Specific Booking Strategies

• Monsoon Strategy (June–September): Book Havelock–Neil tickets at least 6 days in advance due to the restricted 19% capacity retention. Retain flexible hotel booking policies in case of adverse weather cancellations enforced by the Ministry of Ports, Shipping and Waterways.
• Peak Season Strategy (October–February): Secure high-speed catamaran seats on Makruzz or Nautika 14 to 30 days early, especially for morning departures out of Port Blair.

Maritime Infrastructure and Regional Connectivity Assessment

The extreme seasonal variance in Andaman ferry availability impacts local hospitality logistics, supply chain stability, and island community connectivity. Private operators such as Green Ocean and ITT Majestic adjust fleet dry-docking and annual maintenance cycles during the June–September window to align with lower demand.

REGIONAL INFRASTRUCTURE IMPACT MATRIX

Column 1
Primary Hub (Port Blair): Sustains 43% monsoon capacity; acts as core anchor.
Secondary Link (Havelock): Acts as central tourist transit terminal.
Feeder Link (Neil Island): Retains 19% capacity; vulnerable to weather locks.

Because secondary links like Havelock–Neil maintain only 19% of their peak volume in monsoon, hoteliers on Neil Island operate at reduced capacity. Conversely, the 43% capacity retention between Havelock and Port Blair ensures essential inter-island mobility for residents, medical transport, and cargo movement throughout the rainy season.
