Chennai

Is Chennai safe?

Yes. For a visitor, Chennai is one of the calmer big cities in India. The National Crime Records Bureau (NCRB) counted 105 murders in 2024, about 1.2 per 100,000 residents on the population it uses, and recorded crime against women was lower per resident than in any other of India's 19 big cities. The dangers that hurt people here are the roads, the weather between October and December and, for a few months a year, the air.

We score Chennai 68 out of 100, a point above Mumbai and well above Delhi. It is a point above Kolkata, which records even less crime but has worse air. Our India page covers the rest of the country.

Crime and women's safety

The numbers are low for a city of its size. Chennai police registered 15,765 cases under the main criminal codes in 2024, a rate of 181 per 100,000 against 279 in Mumbai and 1,688 in Delhi. There were 2,876 thefts, about a quarter of Mumbai's count. NCRB itself warns that cities should not be compared on crime figures alone, since the data come from state police forces and recording differs, but Chennai sits near the safe end on every measure.

For women, the gap is wider. Chennai recorded 1,093 crimes against women in 2024, 25.4 per 100,000 women, the lowest rate of the 19 big cities; Delhi's was 176.8. That does not mean harassment is absent. The UK Foreign Office (FCDOFCDO travel adviceThe UK government's travel advice for each country, which can advise against all travel or all but essential travel to specific areas.More in the glossary) says female travellers in India often face verbal and physical harassment and advises against travelling alone or hailing taxis on the street at night.

Practical steps:

• Use Uber, Ola or a hotel car after dark and share the trip with someone.
• Dress conservatively at temples and in older neighbourhoods.
• Keep drinks in sight; the FCDO reports spiked food and drinks used to rob travellers in India.
• Keep phones in a front pocket on crowded buses, suburban trains and at stations.

Roads and getting around

Traffic is the bigger risk. The road transport ministry (MoRTH) counted 542 road deaths in Chennai in 2024, up from 503 the year before and the 10th most of India's 50 million-plus cities. That is about 6 per 100,000 on the 2011 census population, far below Bengaluru's 894 deaths but well above Mumbai's rate.

Take app cabs or the Metro for longer trips, cross at signals, and be careful at night, when the FCDO says accidents and crime both rise. Do not ride a scooter unless you already ride in heavy traffic at home.

Cyclones, floods and heat

Chennai's weather is its biggest natural risk. Most of its rain falls from October to December, and the FCDOFCDO travel adviceThe UK government's travel advice for each country, which can advise against all travel or all but essential travel to specific areas.More in the glossary says tropical cyclones threaten India's east coast from September to December. In December 2023, Cyclone Michaung's rains killed at least 12 people in Chennai and flooded roads, the airport and train stations, according to The National.

If you travel in those months, check the India Meteorological Department forecast, book flexible tickets and stay in a hotel above street level. Do not wade through floodwater, which can hide open drains and live cables. April to June is hot and humid; plan sightseeing for mornings and evenings. Strong currents make Marina Beach a place to walk, not swim.

Air, water and health

Chennai's air is cleaner than most big Indian cities' but still well above safe levels. The Central Pollution Control Board's continuous monitors averaged about 27 µg/m³ of PM2.5PM2.5Tiny airborne particles 2.5 micrometres across or smaller. They reach deep into the lungs and are the air pollutant most linked to early death.More in the glossary in 2024 and 30 in 2025, according to the Centre for Research on Energy and Clean Air (CREA), five to six times the WHO guideline of 5. The worst months are November to January, when monthly averages rose to 43 to 53 in 2025. Delhi's yearly average was about three times higher.

Tap water is not safe to drink.

The FCDO notes that government and private care is available in major cities, and Chennai's private hospitals are good if you have insurance.

How we scored it

Violent crime (86) is Chennai's strongest factor, and night safety (69) sits at the top of its band because of the low rate of crime against women. Theft and scams (70) is solid. Traffic (52) and natural hazards (52) are the weakest, for road deaths and east-coast cyclones and floods, and health and environment (58) reflects air that is moderate by Indian standards but unhealthy by global ones.
