Conhecer o clima local é um fator importante para planejar os recursos hídricos, haja vista que vários elementos meteorológicos estão inseridos no ciclo hidrológico. Nesse contexto, o objetivo deste trabalho é avaliar a estimativa dos balanços hídricos climatológicos (BHC) e suas classificações segundo KÖPPEN e THORNTHWAITE & MATHER para a área da bacia do rio Uruçuí Preto na Chapada da Manabeiras, PI. Os meses de maiores insolação ocorrem entre maio a outubro com flutuações variando de 223,0 a 297,1 horas e décimos. A umidade relativa do ar oscila entre 60 a 80% nos meses de novembro a maio. A retirada de água na área da bacia hidrográfica do rio Uruçuí Preto ocorrem nos meses de agosto a janeiro, as deficiências hídricas ocorrem entre os meses de outubro a janeiro, a reposição das águas acontecem nos meses de fevereiro e março e os excedentes hídricos ocorrem entre os meses de abril a julho, desta forma conclui-se que a comunidade ribeirinha utiliza-se de sistema de irrigação nas atividades agrícolas independente dos períodos seco ou chuvoso. Knowing the local climate is an important factor to consider water resources, considering that various meteorological elements are embedded in the hydrological cycle. In this context, the aim of this work is to evaluate the estimation of climatological water balance (BHC) and their classifications on KÖPPEN and THORNTHWAITE & MATHER to the area of the river basin on Uruçuí Preto Chapada da Manabeiras, PI. The months of greatest insolation occur between May to October with fluctuations ranging from 223.0 to 297.1 hours and tenths. The relative humidity ranges from 60-80% in the months from November to May. The withdrawal of water in the catchment area of the River Uruçuí Preto occur in the months from August to January, water deficit occur between the months from October to January, the replacement of water occur in the months of February and March and water surpluses occur between the months from April to July. thus concludes that the riverside community makes use of the irrigation system in agricultural activities independent of the dry or rainy.
