Abstract: The rainfall data of costal district Puri for 20 years (1995-2014) were collected from Special Relief Commissioner (SRC), Government of Odisha, Bhubaneswar were analyzed by using the method of incomplete gamma probability, to estimate annual, seasonal, monthly and weekly rainfall probability. The data revealed that the average rainfall during last 20 year of Puri district 1449.3mm. During monsoon (Jun–September) Puri 1109.9 mm rainfall which contribution about 74.2 annual rainfall. During post monsoon (October-November) winter (December-February) and summer (March-May) Puri received about 251.7 mm (16.8%), 12.7 mm (0.8%), 120.7 mm (8.0%) rainfall. Highest rainfall was receiving in the month of August 382.4mm in Puri District. The total annual predicted rainfall of the district at 90%, 75% and 50% probability are 1052.1 mm, 1236.9 mm and 1466.8 mm respectively. At 75% probability the district received very less rainfall (<5mm) before the onset of monsoon that is before 24th Standard Meteorological Weak (SMW). But at the beginning of monsoon in SWM 24, 25 and 26 the district may receive a fair amount of rainfall. After SMW 28th a very good amount of rainfall may be received up to SMW 38th and decreased thereafter upto 41th week that is the cessation of monsoon. All SMW between 25 to 38th is expected to get rainfall above 30 mm rainfall. At 75% probability where was from SMW 25th week 40th week at 50% probability. The Risk proof crop which can be best suitable for Kharif season are rice in puri, medium and low land and non paddy crops like groundnut pulses soybean can be taken. During winter season pulses like black gram, green gram and oil seeds like sesame, groundnut can be taken.
