As the state of Rajasthan was found by merging the princely states, it has many dialects.
 
The four main dialects are Marwari (in western Rajasthan), Jaipuri or Dhundhari (in the east and southeast), Malvi (Malwi; in the southeast), and, in Alwar, Mewati is spoken, which shades off into Braj Bhasa in Bharatpur district.
 
The main language written and spoken is Hindi.English is also commonly understood, except at the grass root levels. However, tourist guides and translators are also available in French, Spanish, German and Japanese.

Rajasthan is culturally rich and has extensive tradition in art and culture, which reflects Indian way life. The dance, music and art forms have been watchfully cultivated and patronised by the erstwhile courts. An equally rich and varied folk culture from villages is both fascinating & mesmerising. The music is of uncomplicated innocence and songs depict day-to-day relationships and chores more often focal around bring of water. Rajasthan's cultural tapestry takes in simple folk to highly cultivated classical music and dance in its own distinct style.

The mixture and brilliance of Rajasthan's architectural heritage can amaze a visitor. Majestic forts, intricately carved temples and havelis (meaning mansion) and even step well make Rajasthan a paradise for an architecture buff. The desert state of Rajasthan is a land of irony and extremes. This vibrant and striking region is the home of the Rajput warrior clans who had ruled here for many years. Rajasthan is also home to some of India's most romantic cities. The Rajputs were prolific builders and have dotted the arid Aravali landscape with their legacy of some most imposing and magnificent forts and palaces in the world. Today the structures defy time to tell the story of gallantry, courage and tragedy of the bygone era and its story of survival in the harsh Thar Desert.

The climate of Rajasthan can be divided into four seasons: Summers, Monsoon, Post-Monsoon and winter.

A summer, which extends from April to June, is the hottest season, with temperatures ranging from 32 degree C to 45 degree C. In western Rajasthan the temp may rise to 48 degree C, particularly in May and June. At this time, Rajasthan's only hill station, Mt Abu registers the lowest temperatures. In the desert regions, the temperature drops at night. Prevailing winds are from the west and sometimes carry dust storms (we call them aandhi).

The second season Monsoon extends from July to September, temp drops, but humidity increases, even when there is slight drop in the temp (35 degree C to 40 degree C). 90% of rains occur during this period.

The Post-monsoon period is from October to November. The average maximum temperature is 33 degree C to 38 degree C, and the minimum is between 18 degree C and 20 degree C.

The fourth season is Winter or the cold season, from December to March. There is a marked variation in maximum and minimum temperatures, and regional variations across the state. January is the coolest month of the year. And temp may drop to 0 degree C in some cities of Rajasthan, like Churu. There is slight precipitation in the north and northeastern region of the state, and light winds, predominantly from the north and northeast. At this time, relative humidity ranges from 50% to 60% in the morning, and 25% to 35% in the afternoon.
