Abstract
The article proposes to identify the rainfall pattern for the municipality of Feira de Santana-BA. For this purpose, two statistical techniques were applied to propose the ordering of the indexes, both monthly and annual, namely, Sturges formula and the quartile technique. The treatment of the data took place through the tabulation, elaboration of graphs and tables, which were executed in the Excel and Qtiplot software. As a synthesis of the results generated, the technique of representation by the box plot graphs and the summary table is used. It was found that the greatest variability occurs in the summer, highlighted by the occurrence of variability and high rainfall that trigger hydrometeoric impacts. Less variability in spring, seasonality with greater predictability of reduced rainfall volumes.
