Abstract: 
In the semi-arid region, where water resources are scarce and seriously extinct due to excessive exploitation, it is essential to estimate water needs with greater precision, In this view, the objective is to analyze and understand the variability of rainfall rates and the evaporative power of the municipality of Juazeirinho - Paraiba in the period 1962-2018, The monthly and annual precipitation data for the 57-year period were obtained by the Executive Agency for Water Management of the State of Paraiba, and the graphs of annual variations, Monthly and seasonal averages of precipitation to satisfactorily represent the region's pluviometry regime the software Estimated-T estimated the thermal data for the same period of the rainfall data, where the evaporative indices were calculated by the computation of the water balance, The analysis of the spatial and temporal variability of rainfall provides information on how rural and urban people should establish measures for capturing rainwater and storing it using the wettest period, The variations in rainfall over the years are linked to the phenomena of macromeso and microscales, being of great influence for the rainfall regimes of the municipality, Possibility of extreme climatic events due to the high spatial-temporal variability of precipitation will provide drought events as well as intense precipitation in a short time interval.
