Area geography

Located on the eastern coast of India in the state of Tamil Nadu, Chennai lies on a flat coastal plain with an average elevation of 6 meters. Since it also lies on the Thermal Equator, Chennai remains hot for most of the year. However, its vicinity to the sea lends it some cool breezes.

Typical of any coastal area, Chennai too has a tropical climate. Based on land, Chennai is divided in three regions - Sandy (Adyar, George Town, Santhome), Clayey (T Nagar, Perambur, Anna Nagar) and Hard-rock areas (Guindy, Velachery). There are two small rivers namely Cooum River (in the centre) and Adyar River (in south) that navigate through the city.

Cellular service for tourists

Chennai boasts of an excellent telecommunication system. More than 10 mobile phone companies operate GSM and CDMA networks in the city wherein four of them are landline firms. Also, mobile internet is widely available across all major mobile networks.

Wifi internet

Being the metropolitan and capital city of Tamil Nadu, Chennai enjoys great internet and Wi-Fi connectivity. Not many know that Chennai was the first Indian city to have Wi-Fi facility. Whether it is hotels, restaurants or cafés, they all offer either Wi-Fi or broadband internet. Besides that, there are a number of cyber cafes in the city to ensure you are well-connected to the cyber world.

Drinking laws

The legal drinking age in Chennai is 21 years.


Tipping is often welcome in India by most of the waiters and clerks. If food and beverage outlets add a service charge in the final bill, tipping is not necessary. However, small tips for good service are always appreciated.


Chennai is generally considered relatively safe for tourists. However, petty crimes like pickpocketing or bag snatching are common. It’s advisable to always be cautious of your surroundings and avoid visiting isolated areas.
