Plan your trip · best season, weather & crowds
Best time and best season to visit Andaman, decided honestly
The short answer every site gives you — "October to May" — is true and nearly useless, because the right month depends on what you are optimising: weather, price, or crowds. This is the version we give our own guests, with the season-by-season picture and the month-by-month verdicts on one page.
The verdict, up front
- Start with the weather pattern. October to May is the usual planning window; confirm the conditions and operation of your chosen activities for your dates.
- Compare October and November. Showers are still common in October (about 13 dry days in 30) and November is drier (about 16). Check the weather trade-offs alongside actual airfares and room quotes. A seasonal label does not establish the best value for your trip.
- Check December on its own merits. December averages about 21 dry days in 30 — drier than October and November, though January to April are drier still. Compare the actual room and flight quotes, including any mandatory holiday meals or supplements.
- Monsoon dates need flexibility. A lower quote, if available, comes with weather and activity trade-offs. Allow time around ferries; a final Port Blair night cannot guarantee an onward connection.
The best season to visit Andaman
The best season to visit Andaman is November to April, when the sea is calm and the weather is at its driest: at the Port Blair airport gauge, January to April average 26–28 dry days in every 30, December about 21 and November about 16. October and May are shoulder months, and June to September is the rainy season. The peak tourist season runs from November to January — December is the busiest month in the DGCA arrivals data, with November and January next — and the off-season is the monsoon. These are historical averages, not a forecast for your dates.
| Season | Months | Dry days in 30 | Sea |
|---|---|---|---|
| Dry season — the best season | January–April | 26–28 | Calm; April the flattest |
| Early season | November–December | 16–21 | Calm |
| Shoulder months | October, May | 13–14 | Calming in October; rough spells in May |
| Rainy season (monsoon) | June–September | 9–10 | Rough spells |
Dry days are averages at the Port Blair airport gauge, 2015–2024 (NOAA GSOD); sea notes mirror our weather guide. Crowd levels in the month grid below follow DGCA arrivals at Port Blair, 2023–2025.

The same beach in different conditions — photographed
Words undersell how differently the seasons behave, so here is the same beach — Kalapathar, on Havelock — across four dated frames from our photo library. This is what the table above actually looks like.
All four frames are from our own photo library. Three are dated by the day they were sent to us, which can be later than the day they were taken. The full photo story is on the Kalapathar seasons page.
Compare your dates on the same basis
Ask for the same route, rooms, travellers and inclusions on two date options. Availability and holiday requirements can change the total; a seasonal label alone is not a price quote. Check any mandatory meals or supplements in writing.
Build your trip budget →Best time, by the trip you are planning
Honeymoon
Compare November, December and February using the weather guide and quotes for the same room and experiences. A sea view or special dinner is a choice to specify, not an automatic inclusion.
Family
Compare October–November and February–March around school dates and your preferred pace. If holiday dates are fixed, check the actual rooms, bedding and flight options early.
Snorkelling & diving
The calm-sea months — roughly November to April, with February the standout for water clarity. Monsoon months still run dives on fair days, but visibility and boat comfort are a lottery.
Budget
Compare the same rooms and inclusions across your possible dates. A lower quote can come with different weather or activity trade-offs; choose the trip you want as well as the price.
The timing questions, answered straight
What is the best time to visit Andaman?
Use October to May as a starting point, then compare the monthly weather pattern with your dates and trip priorities. Check current hotel, flight, ferry and activity availability before booking. No month guarantees calm crossings, a particular room or the lowest quote.
Which is the best season to visit Andaman and Nicobar?
November to April. Those are the calm-sea, drier months: the Port Blair airport gauge averages 26–28 dry days in every 30 from January to April, about 21 in December and about 16 in November. October and May are shoulder months, and June to September is the rainy season, with rough spells at sea and about 9–10 dry days in 30. December is the busiest month, with November and January next. These are historical averages, not a forecast for your dates.
Which is the cheapest month to visit Andaman?
There is no guaranteed cheapest month for every departure city and property, so ask for comparable quotes for your possible dates, using the same rooms, party size and activities. What the data does show is demand: in DGCA arrivals data, July is the quietest month (about 39 percent below an average month across 2023–2025) and December the busiest (about 54 percent above). Fewer travellers does not guarantee a lower quote, and the quiet months are the monsoon — allow for weather-related changes when weighing a lower quote against your priorities.
Is December a good time — or overrated?
The Port Blair airport gauge averages about 21 dry days in every 30 in December, against 16 in November and 13 in October — and 26–28 from January to April, the driest stretch of the year. These historical averages are not a forecast for your travel dates. Compare current quotes on the same basis and check mandatory holiday meals or supplements at each property before deciding whether December suits your priorities.
Can I visit Andaman during the monsoon or rainy season (June–September)?
A monsoon trip needs flexible plans. Weather can delay ferries or change boat activities, and the effect varies by day. Check current operation before booking, leave time around transfers and discuss an additional night if your onward connection needs it. A final Port Blair overnight is not a guarantee against disruption.
What is the best month for a honeymoon in Andaman?
November and February are options to compare using the weather guide, your dates and your preferred activities. A sea-view room and a candlelight dinner are optional requests, included only when your written quote specifies them. Confirm the exact room, setup and alternative arrangements rather than assuming every honeymoon has the same inclusions.
How far ahead should I book?
Start checking when you know your dates, especially if a particular room or school-holiday departure is essential. Ask for current availability and cancellation conditions before committing. An enquiry or seven-day quote validity does not hold inventory.

How this page stays true
Written by the Tropical Andamans team in Port Blair from the seasons we operate in. The month grid and season table mirror our weather guide, corrected against the Port Blair gauge on 25 September 2026; the season summary was added on 4 October 2026. Package inclusions and quote-comparison guidance were updated 19 September 2026. Historical weather patterns are not forecasts, and a seasonal label is not a current hotel, flight or package quote.
