It was determined probability to occur equal or superior pluvial precipitation 100% and 60% of themaximum evapotranspiration (ETm) of the common bean, in different sub period and sowing dates, for threelocalities in Rio Grande do Sul State, Brazil. With the daily pluvial precipitation data, determined the accumulationof pluvial precipitation (TPP) in each sub period, sowing date and locality. The adjustment of the data of TPP wasevaluated in each sub period, sowing date and locality, to the distributions normal and gama, using Lilliefors’ testfor first and Kolmogorov-Smirnovs’ test for second. It was verified that the probability the pluvial precipitation beequal or superior of the ETm for common bean in complete cycle were minor in Julio de Castilhos, intermediary inCruz Alta and superior in Passo Fundo. However, between studies localities, Passo Fundo is the local of minorproduction risk. The lesser probabilities had occurred during the sub periods most critical of the culture, understoodbetween the beginning of the flowering and the physiological maturation, when the probabilities are lesser than50%, considering the total ETm. The three sowing dates considered, the lesser probabilities during the completecycle of the culture occurred in October and November, being that in the critical period, the sowing of Septemberpresented the higher probability
