Diving in India: Andamans, Lakshadweep, Goa and Angria Bank
India is not one dive destination. It is several, scattered across two seas and a bay, and they barely resemble each other.
On one side you have Goa, easy to reach and busy, with visibility that usually tops out around 5 to 6 m. On the other you have the Andaman and Nicobar Islands and Lakshadweep, sitting in clear oceanic water with reefs that reward a long flight.
And then there is Angria Bank, a sunken atoll 105 km off the Maharashtra coast. That is the spread. Pick your trip accordingly.
The Andaman and Nicobar Islands
The Andamans sit between India and Thailand, yet they keep Indian time. That geographic oddity tells you something about the water: this is open ocean, not coastal murk.
Around Havelock Island, now Swaraj Dweep, the reef diving is very good, with a great variety of sea life and the kind of visibility that makes a reef read as a whole landscape rather than a series of close-ups.
Getting there takes effort. Flights go from Chennai or Kolkata, which makes the islands a bit hard to reach by design rather than accident. Peak season runs November through April.
Lakshadweep
Lakshadweep is the other half of India's clear-water story. The dive sites cluster around three islands: Agatti, Kadmat and Bangaram.
The season is the interesting part. May through November is the best window here, which is almost the exact inverse of the Andamans. If your leave falls in the middle of the year, Lakshadweep is the answer.
Angria Bank
This is the one divers talk about. Angria Bank is a sunken atoll on the continental shelf, 105 km west of Vijaydurg in Maharashtra, and it is reported to be the largest submerged coral reef in India.
Depth is around 20 m. Access is a two-hour boat ride from Malvan, which means the weather and the boat decide whether your trip happens, not you.
A reef that size, that far offshore? That is a rare thing to be able to put in a log.
Goa and Pondicherry
Goa is one of India's most popular dive destinations, and the honest reason is that it is the easiest to get to. Visibility is usually only 5 to 6 m. Diving runs best from October through May and is not permitted during the monsoon.
Pondicherry has a longer calendar. Its peak season is January through June and again September through November, though diving in the area can be done all year.
Water and weather
India's coasts are tropical. Water temperature across the diving areas ranges between 27 °C and 30 °C, which is about as forgiving a range as the tropics offer. For reference, the average annual air temperature across the country as a whole is 25 °C.
The monsoon is the thing that shapes an Indian dive calendar more than anything else. It closes Goa outright and it is the reason the Andaman and Lakshadweep seasons sit on opposite sides of the year.
Planning a trip
Start with your dates, not your destination. November through April points you east to the Andamans. May through November points you west to Lakshadweep. October through May opens Goa, and Pondicherry fills in most of the rest.
If clear water is the priority, the Andamans and Lakshadweep are where India delivers it, and both take real travel to reach. The Wikivoyage guide to diving in India is a good place to check the regional detail before you commit.
And if Angria Bank is on your mind, remember it starts with a two-hour boat ride out of Malvan. Build the trip around that, not around a hotel.
Three coasts, three seasons, one country. Not many places make you choose like that.
When you get there, log it. Note the visibility at Havelock so the next diver knows what good really looks like, pin your Lakshadweep sites around Agatti, Kadmat and Bangaram, and if you make it out to Angria Bank, post the photos. Start your log at Scubaspot.
