Ashoknagar is situated at the average elevation of 507 metres(1640 ft) above sea level. It is in the plateau region. It has an agricultural topography. The plateau is an extension of the Deccan Traps, formed between 60 and 68 million years ago at the end of the Cretaceous period. In this region, the main classes of soil are black, brown and bhatori (stony) soil. The volcanic, clay-like soil of the region owes its black colour to the high iron content of the basalt from which it is formed. The soil requires less irrigation because of its high capacity for moisture retention. The other two soil types are lighter and have a higher proportion of sand. The year is popularly divided into three seasons: summer, the rains, and winter. Summer extends over the months of Chaitra to Jyestha (mid-March to mid-May). The average daily temperature during the summer months is 35°C, which typically rises to around 46 °C on a few days. The rainy season starts with the first showers of Aashaadha (mid-June) and extends to the middle of Ashvin (September). Most of the rain falls during the southwest monsoon spell, and ranges from about 100 cm in the west to about 165 cm in the east. Ashoknagar and surrounding areas receive an average of 140 cm of rainfall a year. The growing period lasts from 90 to 150 days, during which the average daily temperature is below 30 °C, but seldom falls below 20°C. Winter is the longest of the three seasons, extending for about five months (mid-Ashvin to Phalgun, i.e., October to mid-March). The average daily temperature ranges from 15°C to 20°C, though on some nights it can fall as low as 5°C. Some cultivators believe that an occasional winter shower during the months of Pausha and Maagha—known as Mawta—is helpful to the early summer wheat and germ crops
