Andaman Month-by-Month: Weather & Crowd Table

The table below is the whole year at a glance. Highs and lows are typical daytime figures in degrees Celsius. Each month links to a deeper guide where we have one, so you can drill into a specific month once you have picked your window.

Peak, Shoulder & Off Season at a Glance

If your dates are flexible, the shoulder months reward you the most. October to November and February to May deliver near-peak weather without peak crowds or pricing. Lock your Havelock and Neil ferries early for December and January, when seats sell out fastest. Ready to fix your dates? Plan your Andaman trip.

Best Time by Activity: Diving, Water Sports & Island-Hopping

Scuba diving and snorkelling: best from October to May, peaking February to May when underwater visibility is at its clearest. Dive operators suspend most trips during the July to September monsoon. Havelock’s Elephant Beach and Neil’s Bharatpur Beach are the two gentlest snorkelling entries, both sea-condition dependent, so aim for the calm dry-season mornings.

Island-hopping by ferry: the core of any Andaman trip, and the most weather-sensitive. Inter-island ferries linking Port Blair, Havelock (Swaraj Dweep) and Neil (Shaheed Dweep) run most reliably October to May. During the monsoon expect cancellations and rescheduling, so always keep a buffer day. Ross and Smith, the twin islands joined by a natural sandbar you can walk at low tide, are at their best on the clear, calm days from November to April.

Water sports (jet ski, parasailing, sea walk, banana boat): October to April is the window, when the seas around North Bay and Corbyn’s Cove are calmest and operators run full schedules. For a sense of what is on offer and what it costs, see water sports in Andaman and scuba diving in Andaman.

Trekking and birding: the dry season only. The Saddle Peak climb near Diglipur and the Mount Harriet trails need firm, dry ground, so November to April is the safe window. For birders and sunset-chasers, Chidiya Tapu is at its best from February to May, when clearer evenings make the point one of the finest sunset spots in the islands.

Game fishing and kayaking: November to April for the steadiest conditions. Mangrove kayaking is best on the calmer high-tide windows of the dry season.

Best Time by Traveller: Honeymoon, Family & Friends

Honeymoon: November to February. Calm seas, clear skies and the most romantic beach-and-sunset weather, ideal for a private sandbank picnic or a candlelight dinner. Time an evening at Radhanagar Beach on Havelock for the sunset, then look at our Andaman honeymoon packages for the couple-friendly stays.

Family: December to March. The most predictable weather, gentle seas for first-time snorkellers, and the widest choice of kid-friendly boat trips. The evening light-and-sound show at the Cellular Jail in Port Blair runs year-round, and the clear, dry-season nights make it an easy, low-effort outing with children.

Friends and adventure groups: February to May. The best diving and water-sports window, with warm weather and good shoulder-season value before the monsoon. This is also when the Ross and Smith sandbar and the outer snorkelling reefs are most reliably open.

Festivals & Events Calendar: When to Time Your Trip

Andaman’s event calendar is small but worth planning around, both for the atmosphere and for the effect on prices. The two big draws fall inside the peak dry season, so if you want the festivals and the best weather, the same December-to-January window does both jobs.

If you are chasing the festivals specifically, the safest single window is the last week of December into the first half of January. Peak weather, the Island Tourism Festival and the New Year celebrations all overlap. Just accept that it is also the priciest fortnight of the year.

When to Avoid Andaman: Monsoon, Closures & Festivals

The months to be cautious about are July to September, the peak of the southwest monsoon. Heavy rain and rough seas frequently suspend ferries to Havelock and Neil and pause most water sports, so itineraries can change at short notice. Travel is still possible, prices are at their lowest and the islands are green and uncrowded, but only if you keep flexible dates and a buffer day. For a closer look, read Andaman in June: weather and is it worth it.

Two seasonal closures catch people out. The glass-bottom and snorkelling islands of Jolly Buoy and Red Skin, inside the Mahatma Gandhi Marine National Park, are open only from roughly November to May and alternate year to year, so confirm which one is open for your dates. Boat trips to the Barren Island volcano and the far outer islands are also monsoon-dependent and often paused from June to September.

Andaman also sees a milder northeast monsoon spell around November into December, usually short showers that rarely disrupt a well-planned trip.

Climate in Andaman: Season by Season

Summer in Andaman (April to early June)

Summer in Andaman runs from roughly April into early June, with warm, humid days and highs in the low 30s Celsius. Through April and early May the sea stays mostly calm and underwater visibility is at its yearly best, which makes this a strong window for divers and snorkellers who do not mind the heat, and it carries better shoulder-season value than the December peak. It is a good season, not the peak one. By June the southwest monsoon arrives, seas turn rough and ferries start getting cancelled, so late June onward is best avoided. The best window overall stays October to May.

Monsoon in Andaman (July to September, plus a milder spell)

Andaman gets most of its rain from the southwest monsoon between July and September, when downpours are heavy and seas are rough enough to suspend ferries and water sports. Temperatures stay pleasant, roughly 22 to 34 degrees Celsius, but tropical storms and high tides can close beaches at short notice, and this is the true off-season for tourism. There is also a milder northeast spell around November into December that brings occasional short showers and rarely disrupts a trip. If you want the islands at their greenest and cheapest, and you can stay flexible, the monsoon has its own appeal.

Winter in Andaman (October to March)

Sitting close to the equator in the middle of the ocean, Andaman never really gets a cold winter. Temperatures dip only slightly, staying between about 19 and 30 degrees Celsius. October to March is therefore the most comfortable stretch for adventure activities and long, easy beach walks, with calm seas, clear skies and only the occasional shower. For most travellers this, together with the tail of the dry season into May, is simply the best time to be in the islands.

Planning Your Andaman Dates

If you want the simplest answer: go between October and May, aim for December to January if you want guaranteed weather, or February to May if you want the best diving and better value. The monsoon months are for flexible, budget-minded travellers only. Once you have a window, browse Andaman tour packages or read the wider Andaman travel guide to shape the rest of your trip.
