The ocean-atmosphere interaction acts as a force for hydrological systems at different time scales, El Niño-Southern Oscillation (ENSO) being one of them. This paper presents the analysis of hydrometeorological variables and their association with the Oceanic Niño Index (ONI), representative of ENSO, in the Upper Basin of Neuquén River (UBNR) for the period 2000-2014; detecting a weak correlation (r of 0,35). Precipitation, temperature and SWE presented weak and moderate associations, with a r lower than 0.44, 0.23 and 0.36 respectively, without a defined behavior for the different phases of ENSO; while the SCA presented a very weak correlation, between -0.07 and 0.14. Correlation between the flow and the ONI was 0.51 for the entire period and 0,31 for the El Niño phases with a 5% of significance, without being significant for La Niña periods.
