Peak Season: December to February

This is when most of India travels to Andaman, and for good reason — the weather is at its best: low humidity, clear skies, and calm seas perfect for ferries and water sports.

Pros: Best weather, calmest seas, ideal diving visibility Cons: Highest hotel and ferry prices, advance booking essential (especially for Radhanagar Beach-facing resorts and popular dive slots), Christmas/New Year week books out weeks ahead

Shoulder Season: October–November and March–May

This is the value window many seasoned travelers prefer.

October–November: Weather is improving post-monsoon, seas are calming down, and prices haven’t yet hit peak-season levels. Some ferry disruption risk still exists early in the month.

March–April: Weather is still good, prices are easing down from peak, but humidity and heat start climbing by late April. This is also a strong window for diving, as visibility tends to be excellent.

May: The transitional month — still mostly fine for travel, but early monsoon showers can start appearing in the back half.

Monsoon Season: June to September

Most tour operators discourage travel during this window, and there are real reasons why:

  • Ferries between islands face more frequent cancellations due to rough seas
  • Outdoor activities like beach time and water sports are weather-dependent and can get cut short
  • Some hotels offer significant discounts, which is the main appeal for budget travelers

Who should still consider it: Budget-conscious travelers who are flexible with plans and don’t mind some days being rearranged due to weather. It’s not recommended for short, fixed-itinerary trips since a single rough-weather day can derail a 3-day plan.

Best Month For Specific Goals

Goal Best Month(s)
Diving visibility January–April
Lowest overall prices June–August (with weather trade-offs)
Fewest crowds + decent weather October–November
Honeymoon weather December–February, or October–November for better rates
Avoiding peak-season crowds entirely September or May

Our Recommendation

If your dates are flexible, November or February offer the best balance — good weather, manageable prices, and fewer crowds than the Christmas/New Year peak.

If you’re locked into peak season dates, book your hotels, ferries, and activities at least 4-6 weeks in advance — popular resorts and dive slots fill up fast.
