Scuba diving here isn't just a sport—it's an ethereal experience filled with vibrant coral reefs, diverse marine life, and clear blue waters. But to truly make the most of your dive, timing is everything.
From November to May, Andaman offers its most welcoming underwater conditions. These months promise calm seas, excellent visibility, and thriving marine ecosystems. Whether you're a beginner or a seasoned diver, knowing the best time for scuba diving in Andaman is the key to a memorable experience.
In this comprehensive guide, we will uncover the ideal months, seasonal variations, marine life sightings, safety tips, and everything in between. Let’s deep-dive into Andaman’s scuba diving calendar!
Understanding Andaman’s Diving Seasons
November to May – The Prime Scuba Diving Season
The window between November and May is widely considered the best time for scuba diving in Andaman. These months offer the perfect blend of weather and sea conditions, ideal for both first-time and certified divers. With sea temperatures hovering between 26–30°C and visibility often exceeding 25 meters, diving during this time is an absolute treat.
Furthermore, underwater currents are mild, and there’s little to no rainfall—making for safer and more enjoyable dives. The sunlight penetration is also optimal, giving you stunning underwater visibility and enhancing the colors of corals and marine life.
June to September – The Monsoon Period
The monsoon season, spanning June to September, brings with it heavy rains, strong winds, and rough seas. During this time, most dive operations pause due to safety concerns. Visibility drops significantly, and the chances of dive cancellations rise. Although the islands retain their charm above water, diving during monsoon is not advisable.
If your travel is flexible, it’s best to avoid these months and plan your visit during the dry season to ensure you don’t miss the world-class diving experience.
October and Early November – Transition Phase
October and early November represent a transitional phase from monsoon to dry season. The weather begins to stabilize, and diving conditions gradually improve. While not as perfect as the peak months, October still offers decent visibility and fewer tourists, making it a sweet spot for early planners.
Some diving schools may start operations in late October, offering special packages for those willing to take a slight chance on weather conditions.
Best Locations for Diving During Peak Season
Havelock Island – The Crown Jewel
When discussing the best time for scuba diving in Andaman, Havelock Island (now officially Swaraj Dweep) deserves a spotlight. From December to April, its dive sites like The Wall, Dixon’s Pinnacle, and Elephant Beach are at their most vibrant. You can expect crystal-clear visibility and encounters with barracudas, groupers, and colorful reef fish.
The island’s calm water and beginner-friendly conditions also make it ideal for introductory dives and PADI certification courses.
Neil Island – Pristine and Underrated
Neil Island (Shaheed Dweep) is a hidden gem for divers seeking serenity. The dive sites around Neil, such as Junction and Bus Stop, come alive between November and March, offering a tranquil experience. The reefs here are less disturbed, and sightings of sea turtles and rays are common.
For photographers and underwater explorers, this island is a dream during the early dry season months.
North Bay and Port Blair – Beginner’s Heaven
For those short on time or diving for the first time, Port Blair and North Bay Island offer convenient and safe dive options. The best time here mirrors the overall season—November to April. These areas are excellent for half-day trips, shallow reef exploration, and snorkeling alongside scuba sessions.
Marine Life Encounters by Season
Dry Season Marvels (November to May)
During the peak diving season, Andaman’s marine biodiversity flourishes. Expect to witness:
-
Reef sharks in deeper dive sites
-
Manta rays during the late dry season
-
Clownfish, angel fish, and parrotfish
-
Moray eels and octopuses hiding in crevices
-
Beautiful coral gardens in full bloom
The calm conditions during these months ensure marine life isn’t agitated by strong currents or disturbed sediments, leading to longer and more fruitful dives.
Rare Sightings and Seasonal Variations
From January to March, there's a higher chance of spotting larger pelagic species. These months are often associated with mating seasons, increasing the likelihood of rare sightings.
On some occasions, dolphins can also be spotted on the boat ride to the dive sites. While not guaranteed, their presence during this time adds a magical bonus to the journey.
Tips for Planning Your Scuba Diving Trip
Book in Advance During Peak Months
As November to May is the best time for scuba diving in Andaman, it also coincides with India’s tourism peak season. This means flights, ferries, and accommodations can get booked quickly. Always plan your trip at least 1–2 months in advance, especially if you’re traveling during December or January.
Pack the Right Gear
Although diving schools provide equipment, consider bringing personal gear like:
-
Dive mask with prescription lens (if needed)
-
Rash guard or wetsuit
-
Underwater camera or GoPro
Also, don’t forget reef-safe sunscreen and a dry bag for your boat trips.
Health & Safety First
Before diving, ensure you:
-
Have no respiratory or heart conditions
-
Avoid alcohol and heavy meals before a dive
-
Listen carefully to dive briefings
-
Follow buddy systems and depth limits
It’s also recommended to rest for 18–24 hours before taking a flight after your final dive to avoid decompression sickness.
