Do I really need a jacket for India?

Yes, if you go north of Delhi between November and February. The temperatures can drop to near freezing at night, and many guesthouses lack central heating.

Can I buy clothes there instead of packing them?

Absolutely. You can buy high-quality, inexpensive cotton kurtas and trousers at local markets. Pack light and buy what you need locally to save space.

What is the one thing I shouldn't forget?

A solid pair of slip-on shoes. You will be taking your shoes off constantly to enter homes, shops, and temples.

How to Pack for India's Diverse Climates

Pack modular layers because India's climate shifts drastically between the arid northern winters, the humid monsoon season, and the scorching tropical heat. Prioritize breathable natural fabrics like linen and cotton for the majority of the country, while adding a heavy fleece or down jacket if you are visiting the Himalayas or North India between November and February.

Assess your specific region. Divide your trip into three zones: The North (Delhi, Rajasthan, Himalayas), The South (Kerala, Tamil Nadu, Goa), and The Northeast. If you are hitting the Himalayas, you need cold-weather gear; if you are staying in the South, you need lightweight, modest clothing.
Prioritize natural fabrics. Avoid synthetics. Stick to 100% cotton, linen, or bamboo. Synthetic fabrics trap sweat and odor in India's high humidity, leading to skin irritation and discomfort. Choose loose-fitting cuts that allow for airflow.
Respect the dress code. Regardless of season, shoulders and knees should be covered when visiting religious sites or rural areas. Pack a lightweight cotton scarf or a pashmina; it works as a modesty cover-up, sun shield, and an extra layer on chilly train rides.
Prepare for the monsoon (June–September). If traveling during the monsoon, ditch the umbrella. Pack a high-quality, lightweight rain poncho that fits over your daypack and quick-dry sandals (like Tevas or Chacos) rather than leather shoes, which will mold in the humidity.
