Packing List · From India
Andamans packing is summer beach gear plus reef-safe sunscreen. The Indian sun in December at 13 degrees latitude is brutal.
Tropical year-round (22 to 33C). December to March is dry. June to September is heavy monsoon and most ferries cancel.
Carry digital copies of everything in your phone plus a backup printed copy in your checked bag.

Pack light. Most destinations have laundry. Plan around layers, not full outfits.
TSA-compliant containers if flying with carry-on only.
Indian plugs, so no adapter is needed.

Items that are non-obvious for this destination.
A copy of your Aadhaar or voter ID. No power adapter is needed in India. Other forgotten items: modest layer for religious sites, swimwear if there is any beach plus pool access.
Most items can be bought locally but at premium tourist pricing. Specialty items (hiking gear, prescription medications) should come from India. Generic items (toothpaste, sunscreen, basic clothing) are cheaper to buy on arrival.
No forex is needed in India. Carry some INR cash for tips plus small vendors. Major restaurants plus hotels accept cards. ATM withdrawals incur 3 to 5 percent fees.
Carry a doctor's prescription with brand plus generic names. Pack medications in original packaging. Some countries restrict specific medications (sleeping pills, ADHD medications); check the destination's customs before travel.
Carry-on essentials: Aadhaar or voter ID, medications, one day of clothing, valuables. Checked bag for everything else. Pack assuming the checked bag may be delayed 24 to 48 hours.
