Quick answer: The Andamans are warm all year (roughly 23–31°C), but the sweet spot is October to March — clear skies, calm seas, and every water sport open for business. The monsoon (June to September) brings heavy rain and choppy crossings, so it's the season to avoid if beaches and diving are your priority. Below is the full month-by-month breakdown to help you pick your dates, plus suggested itineraries and tips.
The islands sit in a tropical belt with very little temperature swing across the year. What really changes is the rain and the sea state—and that's what decides whether you're snorkeling in glassy water or watching a storm roll in from your hotel balcony. Here's what each month is really like.
January
- Weather: Warm and dry, around 27–30°C, with almost no rain.
- Activities: Prime diving and snorkelling with superb visibility; beach-hopping at its best. New Year buzz lingers in Port Blair.
- Pros: Clear skies, calm seas, peak water sports.
- Cons: Peak season — expect crowds and higher prices.
- Best for: Beaches, sightseeing, scuba diving.
February
- Weather: Much like January, it is dry and pleasant, with temperatures around 27–30°C.
- Activities: Excellent for island-hopping between Havelock and Neil, with clear water for spotting marine life.
- Pros: Romantic, festive atmosphere (a favourite for Valentine's trips).
- Cons: Still high season, so tours stay busy.
- Best for: Diving, honeymoons, family trips.
March
- Weather: A touch warmer at 28–32°C, still with minimal rain.
- Activities: Sea activities carry on—snorkelling, kayaking, and long beach days with balmy evenings.
- Pros: The warmest of the dry months, with thinner crowds than the winter peak.
- Cons: Humidity begins to creep up.
- Best for: A final round of scuba diving before the monsoon.
April
- Weather: Hot, 30–33°C, with the odd passing shower.
- Activities: Early April often has the year's best underwater visibility — a dream for divers and underwater photographers.
- Pros: Off-season rates on hotels and tours; noticeably fewer travellers.
- Cons: High daytime heat and humidity.
- Best for: Budget travel, quiet beaches, and the last memorable dives of the season.
May
- Weather: Very hot and humid, 30–33°C; the first monsoon showers may arrive late in the month.
- Activities: Best enjoyed in the cooler mornings — sightseeing and short trips early on.
- Pros: Great hotel deals and near-empty beaches.
- Cons: Peak heat and rising rain; some tours begin winding down.
- Best for: Peaceful morning beach walks and bargain stays.
June
- Weather: Monsoon begins — heavy rain and occasional storms, around 27–31°C.
- Activities: Most boat transfers and water sports pause. Lean into land-based options: museums, markets, and jungle walks when it's safe.
- Pros: The quietest tourist traffic of the year and lush green scenery.
- Cons: Frequent downpours, unreliable ferries, and some attractions closed.
- Best for: Budget travellers who love moody monsoon landscapes.
July
- Weather: Peak monsoon — very heavy rainfall and rough seas.
- Activities: Sea trips aren't advisable. Use Port Blair as a base for indoor sights like the Cellular Jail and the local markets.
- Pros: Tranquil, glistening rainforests and deep off-season discounts.
- Cons: Travel disruptions and cancelled ferries; limited activities.
- Best for: Soaking up lush nature and solitude, if you don't mind the rain.
August
- Weather: Similar to July — high rainfall and humidity.
- Activities: Same caution as July; underwater activities remain closed.
- Pros: A lucky dry spell can open up some jungle trekking.
- Cons: Continual heavy rain and very limited travel.
- Best for: Committed nature lovers only.
September
- Weather: The monsoon starts to weaken later in the month, though it's still wet early on.
- Activities: By late September, occasional clear spells allow limited snorkelling or kayaking.
- Pros: Rain begins tapering while the scenery stays vividly green.
- Cons: Early-month storms are still possible.
- Best for: Late-monsoon deals — aim for the final week as skies start to clear.
October
- Weather: End of the monsoon — rainfall drops sharply and skies clear.
- Activities: Ferries return to regular schedules; water turns clear and diving reopens.
- Pros: Green landscapes and fine weather, right at the start of dive season.
- Cons: A few unpredictable showers early in the month.
- Best for: Underwater sports and sightseeing before the peak-season crowds.
November
- Weather: Dry and comfortable, 26–30°C.
- Activities: Prime season kicks off — snorkel at Havelock and Neil, and hop between islands.
- Pros: Calm seas and near-perfect dive and snorkel conditions.
- Cons: Nothing major; crowds only build gradually.
- Best for: Marine activities, kayaking, and unhurried beach time.
December
- Weather: Dry, sunny, and at its best — 25–30°C.
- Activities: Festive peak. Book the big-ticket experiences early: the Cellular Jail light-and-sound show, Radhanagar Beach, and full water sports.
- Pros: The finest weather of the year with everything open.
- Cons: Very busy over Christmas and New Year — reserve well ahead.
- Best for: A full-suite island holiday of beaches, diving, and sightseeing.
