The present study is focused to determine the change in maximum and minimum temperature on monthly, seasonal and annual time scale for the Rajasthan state. Three different climatic indices were calculated to classify the districts of Rajasthan in different classes as per the given condition. Daily temperature data of 24 gridded locations from 1969 to 2005 were obtained from Indian Meteorological Department (IMD) for the study. Three indices that is, Lang (1915. Internationale Mitteilungen fuer Bodenkunde, 5: 312), De Martonne (1923. C. R. 182(23): 1935) and Emberger (1932. Su rune formule climatique et ses applications en botanique. La Météorologie) were calculated to categorised districts in various zones. The results showed that there was mainly increase in both maximum and minimum temperature in the period 1987–2005 when compared to previous period 1969–1986. It was observed that there was increased change in annual maximum temperature and direction was towards southwest. Similarly, there was an increased change in annual minimum temperature, and direction of change was towards north-east.
