North Bay Island in December
Andaman & Nicobar Islands, India
Go in December — peak season guarantees calm seas, full activity schedules, and 28–30°C water temps ideal for extended water time.
Peak crowds
December is one of North Bay Island's busiest months. The score rates conditions — weather, access, value — not how many people you'll share them with. Andaman water-sports island busiest Oct–May during calm seas and clear skies; Jun–Sep monsoon/cyclone season sees fewest divers and snorkelers.
December at North Bay is when the half-day reef trip runs at full strength. Underwater visibility at the main reef holds 28-30m. Air 23-29C, water 28C, humidity 70 percent. Sea state is calm enough that the 20-minute Phoenix Bay crossing feels like a flat-water cruise. Sea-walk slots run two an hour from 8:30am and are gone by mid-morning - book the previous evening at any Port Blair hotel desk. Beginner-scuba runs all instructor slots; capacity holds at maybe 30 clients a day. Christmas-NY week (December 22 to January 2) drives 10-day-ahead bookouts and 50-60 percent premium on combined packages. The first 18 days offer the same conditions at 35-40 percent lower hotel costs.
