Best Time to Visit Andaman and Nicobar Islands 2026

November through May is generally the most reliable window for Andaman and Nicobar Islands, with calmer seas, better underwater visibility for diving and snorkelling, and more consistent ferry schedules than the monsoon-affected months. Peak-season crowds and prices concentrate around December-January specifically, within this broader good-weather window.
The Broad Good-Weather Window — November to May
This roughly seven-month window generally offers calmer seas, clearer water for diving and snorkelling, and more reliable inter-island ferry schedules than the monsoon-affected months. Within this broader window, conditions aren't perfectly uniform — some months are considerably busier and pricier than others, discussed below.
December-January — Peak Crowds and Prices
This is Andaman's busiest and most expensive period, driven by winter holiday travel from mainland India, coinciding with generally excellent weather conditions. Book flights, ferries and accommodation well ahead if travelling during this specific window, since availability tightens noticeably compared to the rest of the good-weather season.
February-May — Good Weather, Fewer Crowds
This stretch generally offers similarly good weather and sea conditions to the December-January peak, but with noticeably fewer crowds and somewhat lower prices — a strong option for travellers who want the good-weather window without peak-season congestion, though it gets progressively warmer and more humid moving toward May.
Monsoon Season — June to October
This period brings the Southwest monsoon's effects to Andaman, with rougher seas potentially affecting ferry schedules and diving visibility, along with generally wetter weather. It's not necessarily a bad time to visit for travellers prioritising lower prices and fewer crowds over ideal water-activity conditions, but expect some itinerary flexibility to be needed around weather-dependent activities.
Practical Planning Notes
Regardless of season, check current conditions closer to your travel dates, since year-to-year weather variation exists within these general patterns. See the Ministry of Tourism's Incredible India portal for broader travel planning resources, and search FlightGPT for routes to Port Blair once your travel window is decided.
Matching the Season to Your Trip's Priorities
If diving and snorkelling visibility is the main priority, lean toward February-May within the good-weather window, since crowds are thinner and conditions remain reliable. If a specific holiday-timed family trip is the priority and price is less of a constraint, December-January's combination of good weather and festive atmosphere may be worth the premium. Travellers on a tighter budget who can tolerate some itinerary flexibility around weather may find genuine value in the shoulder months just before or after the monsoon, when prices ease but conditions haven't fully deteriorated yet.
