Abstract: 

Studies on rainfall classification help in planning the amount of water available for the expansion of human, animal, plant, industrial, agricultural and hydrological activities. To analyze which, among the three probability distributions, best fits the historical series of probable maximum monthly precipitation data in the city of São Bento do Una Pernambuco, Brazil between 1921-2020. The maximum annual precipitation for São Bento do Una - PE was analyzed from 1921 to 2020, with data from the Weather and Climate Agency of the State of Pernambuco. Estimates of probable monthly rainfall were determined for levels of 5, 10, 20, 30, 40, 50, 60, 70, 75, 80, 90 and 95% probability using the probabilistic Gamma model, as described by Thom (1958). The maximum precipitation data fit the log-normal, gamma, and Weibull probability distribution functions and best fit the gamma probability distribution function. São Bento do Uma - Pernambuco needs to adopt strategies to coexist with drought, aiming at the economic growth of the municipality.
