The best time to visit Andaman is generally from November to May, with November to March offering some of the most comfortable conditions for beaches, sightseeing, island-hopping and water activities.
However, the ideal time depends on what you want from your trip. December to February is a strong choice if comfortable weather is your priority, while March to May can work well if you are comfortable with warmer conditions. The monsoon period can still be considered if you have flexible plans and do not mind a greater chance of rain or changes to sea-based activities.
This guide breaks down Andaman weather by season and month, the best time for scuba diving and snorkeling, monsoon travel, peak and off-season periods, and when to visit based on the experiences you want to prioritize.
For a broader overview of the islands, trip duration, costs, activities and practical planning, see our Andaman Travel Guide.
Best Time to Visit Andaman at a Glance

For a first-time Andaman trip, November to March is the easiest period to choose if comfortable weather and outdoor activities are your main priorities.
Andaman Weather by Season
Andaman stays warm throughout the year, but rainfall, humidity and sea conditions change across the seasons. These differences matter because they can affect island-hopping, ferry travel, beaches and water activities.
November to February: Pleasant and Popular
This is generally the most comfortable period for an Andaman trip, with conditions that suit beaches, sightseeing, island-hopping and outdoor activities.
It is also the busiest travel period, particularly around Christmas, New Year and other holidays. If you are traveling during these periods, plan your flights, accommodation and ferry connections earlier.
March to May: Warmer and More Humid
Temperatures and humidity increase during these months, but the period can still work well for beach and water-focused trips.
If you are comfortable with the heat, March and April can be useful alternatives to the peak winter season. By May, weather conditions can become more variable, so keep some flexibility in your plans.
June to September: Monsoon
The monsoon brings more frequent rainfall and less predictable sea conditions. Ferry services, boat trips and some outdoor activities can be affected by weather.
This period can work for travelers with flexible itineraries, but it is less suitable if your trip depends on completing several island transfers or water activities on fixed dates.
October: Transition Period
October is a transition month as conditions begin moving away from the monsoon period. Weather can still vary, so travelers should keep their plans flexible, particularly when their itinerary depends heavily on ferries or boat activities.
The main seasonal difference for travelers is not temperature alone. Rainfall and sea conditions can have a bigger impact on your Andaman itinerary.
Best Time for Scuba Diving and Snorkeling in Andaman
If scuba diving or snorkeling is a major part of your Andaman trip, the drier months are generally more suitable for planning these activities. However, underwater visibility and sea conditions can vary by location and day, so no particular month guarantees perfect conditions.
Activity | Recommended Period | What to Consider |
| Scuba diving | November–May | Generally favorable for planning marine activities |
| Snorkeling | November–May | Visibility and sea conditions can vary |
| Island-hopping | November–April | Generally more predictable for ferry and boat travel |
| Beach activities | November–May | Generally more suitable for outdoor beach time |
Important If You Plan to Dive
If you plan to scuba dive, do not schedule your final dive immediately before your flight home. Divers need an appropriate surface interval before flying to reduce decompression-related risks.
For detailed information on diving locations, beginner experiences, snorkeling, safety and what to expect, see our Andaman Scuba Diving & Snorkeling Guide.
Is Andaman Good to Visit During Monsoon?
Yes, Andaman can be visited during the monsoon, but weather and sea conditions are less predictable. Rain can affect ferry crossings, boat trips and some water activities, so travelers should keep their itinerary flexible.
Visit During Monsoon If... | Consider Another Period If... |
| You have flexible dates | You want predictable weather |
| You prefer fewer tourists | Island-hopping is a priority |
| You are comfortable with rain | Beaches and water activities are your main focus |
| You can adjust activities around weather | Your itinerary has tight ferry connections |
If you travel during the monsoon, leave extra buffer around inter-island transfers, particularly if you have a flight from Sri Vijaya Puram afterward.

Best Time to Visit Andaman for Different Experiences
The best time to visit Andaman can vary depending on what you want to do during your trip.
Experience | Better Period | Key Consideration |
| Beaches and sightseeing | November–March | Generally more comfortable for outdoor activities |
| Island-hopping | November–April | More suitable for ferry-based travel |
| Scuba diving | November–May | Sea and visibility conditions can vary |
| Snorkeling | November–May | Actual conditions depend on the location and day |
| Bioluminescence | Around darker, new-moon nights | Moonlight can affect how clearly the glow is visible |
| Turtle nesting | Seasonal winter months | Activity varies by location and year |
If a specific experience is the main reason for your trip, check conditions for that activity when choosing your travel dates, rather than relying only on the general season.
When Is Andaman Most Crowded?
Andaman is generally busiest during the peak winter travel season, with demand increasing around Christmas, New Year, school holidays and other major travel periods.
Travel Period | Crowd Level | What to Expect |
| November–February | Higher | Greater demand for flights, hotels and ferries |
| March–May | Moderate | Warmer weather with less peak-season pressure |
| June–September | Lower | Fewer tourists, but greater weather uncertainty |
| October | Moderate to lower | Transitional weather and variable conditions |
If you are traveling during a busy period, book flights, accommodation and inter-island ferries in advance, especially for multi-island itineraries.
*Traveling outside the peak season may offer better value, but lower prices can come with less predictable weather and sea conditions.
