The weather and its variability are well known to the farming community and have great impact on crop production and have great impact on crop production. Rainfall is one of the most important climatic parameter in crop planning especially in region of rainfed agriculture. In this paper, an attempt has been made to analyze 15 years of rainfall (2001–2015) in Ganjam district in Odisha whose annual normal rainfall 1296.0 mm with 95 rainy days. Probability at different probability level such as 90,75,50 percentage has been analysised. Probability of for receiving more than 100 mm rainfall is only for six months and that is too at 50 percent probability level which is leading to interpretation that rice production is a challenging task in this region. It has been found that at 75 per cent assured probability level rainfall more than 150 mm can be expcted only in August, July and September and this rainfall is hardly sufficient for meeting the water requirement in upland situation. However at 50 percent probability which is equivalent to average condition, cultivation of rice is possible under well water management Condition or else some non rice crop can be taken as an alternative.
