The short answer
When to go to Neil Island (Shaheed Dweep)
December and January are the most comfortable months, with calm seas and pleasant temperatures for beach visits and reef walking. May to September should be avoided: this is when monsoon rains are heaviest and ferry crossings from Port Blair can be delayed or cancelled by rough seas. The island's flat terrain makes it senior-friendly year-round, but dry months remove the added complication of ferry disruption.
