Welcome to Chennai
Practical guidance on local weather, currency, clothing, food, and essential behaviour tips to make your visit smooth and enjoyable.
Money Matters
Currency
The local currency is the Indian Rupee (INR). Common denominations include ₹10, ₹20, ₹50, ₹100, and ₹500 notes.
Conversion rate (as of Sep 2026): $1 USD ≈ ₹94.49 INR | £1 ≈ ₹127.65 INR — rates fluctuate, so check a reliable currency converter.
Cash is widely accepted, but credit cards and digital wallets (Paytm, Google Pay, PhonePe) are popular in urban areas.
Do
Carry small denominations for local markets and taxis.
Don’t
Depend solely on USD cash — it’s rarely accepted outside airports and major hotels.
Plan Ahead
Weather
Chennai experiences a tropical coastal climate — warm, humid, and sunny almost year-round. Temperatures usually range between 25°C–38°C (77°F–100°F).
Do
Keep an umbrella handy — it doubles as shade from the sun and a shield from sudden rain.
Don’t
Leave home without hydration — dehydration sneaks up fast in the coastal heat.
Summer Mar – Jun
Hot and humid, often crossing 38°C. Afternoons can be intense — stay hydrated and wear light, cotton clothing.
Pre-Monsoon Jul – Sep
Warm and sticky, with occasional drizzles and coastal breezes providing some relief.
Monsoon Oct – Dec
Heavy rainfall and occasional thunderstorms during the Northeast Monsoon. Carry an umbrella and avoid low-lying areas prone to waterlogging.
Winter Jan – Feb
Mild and comfortable, with pleasant mornings and evenings — ideal for outdoor activities.
Dress Smart
What to Wear
Chennai’s cosmopolitan culture allows for flexible attire, but comfort remains key. Light, breathable fabrics are preferable given Chennai’s weather.
Do
Bring comfortable walking shoes and a light jacket for cooler evenings.
Don’t
Wear revealing clothing when visiting temples or government offices.
Business / Office
Collared shirts, trousers, blouses, and smart dresses are appropriate.
Casual
Jeans, t-shirts, and comfortable shoes for sightseeing.

Modest clothing is necessary — cover shoulders and knees.
