The knowledge and information on the rainfall dynamics and its distribution over the cropping season are very important for selection of crop varieties and choice of cropping pattern. Block wise historical rainfall data of 24 years (1995 to 2018) of Cuttack District were collected and processed by using Weather cock software to estimate annual, seasonal and monthly rainfall. The analysis of rainfall revealed that the total mean annual rainfall of the district is 1597 mm. Cuttack receives almost 77% of mean annual rainfall during south-west monsoon which is about 1216 mm and it receives 207 mm rainfall during post monsoon season. The initial rainfall probability {P (W)} of getting 20 mm rainfall per week was >30% during 22 Standard meteorological week (SMW) at Cuttack district, hence, field preparation should be done during this period. The initial as well as conditional probability of wet week followed by wet week {P (W/W)} of getting 20 mm rainfall was more than 50% in 23rd SMW, this week is more suitable for sowing of crops. During 44th to 46th SMW (29th Oct. – 18th November) probability of getting 10 mm rainfall per week was more than 30 per cent. This period is suitable for land preparation and sowing of rabi crops. Seasonal rainfall variability varied from 72 to 112% during post-monsoon (October-December) and 123 to 198% in winter (January-February) season. It indicates that there was less dependability on rain fall during rabi season which was favorable for growing of rabi pulses and vegetables in post-monsoon as well as winter period in the rice-fallow area. Proper crop planning with suitable water conservation measures are needed to be adopted to enhance the acreage, production and productivity of kharif as well as rabi crops of the district.
