This paper has the objective of verifying the possible influences of the anomalies of sea surface temperature (SST) in the Equatorial Pacific and in the Tropical Atlantic on the duration of the largest dry spell of the rainy season of the micro-regions of the Paraíba State. Daily precipitation data of the rain gauge stations distributed in the all sectors of Paraíba, for the period from January 1, 1963 to December 31, 1999, the monthly anomalies of SST in the area of the niños: Niño 1+2, Niño 3, Niño 3.4 and Niño 4, and monthly indices of North and South Tropical Atlantic, for the period from October, 1962 to December, 1999, obtained from the Diagnostic Center of Climate of the NOAA were used in this study. Correlations and graphs obtained between the anomalies of SST and the dry spell are analyzed. The results obtained showed that the dry spells of the micro-regions of the Coast and Swamp areas are more influenced by the conditions of anomalies of SST on Tropical Atlantic, while the dry spells of the micro-regions of Cariri/Curimataú and Interior, in the central part and west of the State are influenced by the SST of Equatorial Pacific.
