Climate change has implications for global temperature, a situation caused by increased greenhouse gas emissions into the atmosphere; such changes interfere with rainfall patterns, which may lead to an increase in extreme hydrological events and, consequently, environmental risks and disasters resulting from droughts, floods, landslides and species extinctions. In this sense, the study aims to analyze the scenarios of climate interference on the water resources of the largest dams in the state of Paraíba: Engenheiro Ávidos, Epitácio Pessoa and Complexo Coremas Mãe d'Água, highlighting the need for improvements in the area of water resources management, aiming at preventing a water crisis in the medium and long term. To this end, we used bibliographic research, based on national and international literature, and documentary research, with the collection of secondary quantitative data from time series; through government agency databases, we also had the technological assistance of R statistical platforms, SArima and Arima statistical models, and Dicke-Fuller (stationarity) and Mann-Kendall (trend) tests. In view of this, the results pointed to significant long-term climatological implications for dams, which occurred due to prolonged droughts, the unavailability of quality water resources, high evaporation rates, and the seasonality of water in the semi-arid region of Paraíba during the estimated period.
