Will my clothes get moldy?

Yes, if you leave them damp in a suitcase. Always hang wet clothes in front of a fan immediately upon arriving at your room.

Should I bring a heavy raincoat?

No. The humidity is often over 90%. You will get just as wet from sweat inside a heavy coat as you would from the rain.

Packing for Monsoon Season in India

Prioritize quick-drying synthetic fabrics, waterproof footwear, and a reliable dry bag to protect your electronics. Avoid denim and heavy cotton at all costs, as they will stay damp for days in the high humidity.

Select your fabrics. Pack lightweight, moisture-wicking materials like nylon or polyester blends. These dry within hours if you get caught in a downpour, whereas cotton will absorb water and become heavy and prone to mold.
Choose your footwear. Bring one pair of high-quality, quick-dry sport sandals with a sturdy grip and one pair of lightweight, breathable sneakers. Avoid leather shoes, as they will be ruined by the water and take forever to dry.
Waterproof your gear. Place a dry bag inside your daypack for your camera, passport, and phone. Even if your bag is 'water-resistant,' the intensity of a monsoon deluge will eventually soak through the zippers.
Bring a modular rain shell. Pack a lightweight, unlined rain jacket rather than a heavy raincoat. India's monsoon is warm, so you need rain protection that allows for airflow rather than insulation.
