Piura has been one of the most affected regions by floods due to extreme rain events. In the years of 1982-1983, 1998, and 2017 innumerable losses in infrastructure were registered as a consequence of the “El Niño“ effect, the latter being considered as a product of the unusual increase in sea surface temperature. Analysis of the association between sea surface temperature anomalies (SSTA) and extreme rainfall (ER) which occurred in the north of Peru (Piura región) to describe the behavior of SSTA in relation to large-scale rainfalls. For this, cross-correlations with the application of time lags were used in order to find the intensity in which SSTA and ER are associated. For ER, data were extracted from the Piscop grilled product, which is based on information and calibration of records of meteorological stations. While data for the SSTA was extracted from ERA5-ECMWF calibrated by oceanographic stations. From the analysis was observed that maximum precipitations that are recorded in the Piura region present a greater association and significance less than or equal to 5% when time-lag are applied to SSTA, for 1 month for points ubicated in the regions NIÑO 1 and NIÑO 2, and for 2 months points ubicated in the regions NIÑO 3 and NIÑO 4. Finally, the greatest association originates between the unusual variation of SST produced in the 3.3 SSTA point and the ER whit time-lag of 3 months.
