摘要：Knowing the local climate is a necessary factor for evaluation of water resources, for various weather elements are indispensable throughout the hydrologic cycle. In this context, the objectives of this article are to estimate the climatic water balance and the balance sheet at decadal Thorntwaite and Mather method (1948.1955) to the city of Camalaú - PB and evaluate the main weir behavior in this area. Evapotranspiration is almost four times the amount of precipitation and evaporation is equal to precipitate volume. In climatological analysis of rainfall in the city under study, the months from January to May had the highest rainfall in the decade studied. In the year 2014 the months from March to May there were high rainfall rates. The climatic water balance demonstrates a water deficit of 740.3 mm/year for the year 2014 in the month of April 2014 was water surplus of 24.5 mm. In decadal water balance there is a water deficit of 710.1 mm/year and water surpluses do not occur in any month of the year studied. The variability of the large-scale El Niño (a) active in the study period influenced the rainfall and its location effects.
