Thus, the aim of this study was to analyze climate variability in Barbalha, State of Ceará (CE), focusing on the variations as a means to understand future climate change, in order to analyze the climatic variables that influence agriculture. For this research we used data of maximum air temperature, relative air humidity and total rainfall monthly and yearly in the period 1973-2013, the Conventional Meteorological Station belonging to INMET, city Barbalha - CE. The data showed variations in the temperature of maximum annual air showed great variation among the studied period, also it appears that the relative humidity is being incremented along the series studied, which may be related to increasing temperature.
