The results of an analysis of climate variability associated to the ENSO cycle for the Bogotá Highlands are presented. For this analysis we used data of sea surface temperature (SST) anomalies from the EN1+2, 3, and 3+4 sectors of the tropical Pacific, regional monthly mean air temperature and monthly precipitation. An inverse relationship between SST anomalies and precipitation in the Bogotá Highlands was identified: warm conditions (positive SST anomalies related to El Niño) reduce regional precipitation, while cold conditions (negative anomalies associated to La Niña) increase it. The regional air temperature anomalies have a direct relationship with SST anomalies: a rise of the Pacific SST anomalies correspond to positive air temperature anomalies in the Bogotá Highlands region. The climatic effect of the ENSO cycle over the Bogotá Highlands during 20th century has had important socioeconomic impacts on the region. The El Niño event trigger problems by reducing water resources availability for different uses (supply for population, agriculture, industry), that affects agricultural production and leads to a rise in prices. Under El Niño conditions, the frequency of forest fires increases, which directly affects the regional ecosystems. During La Niña conditions flashfloods, landslides (in zones with steep slopes), and floods in lowlands (especially the sectors near the Bogotá, Tunjuelo and San Cristobal rivers) occur; these phenomena directly affect properties in rural and urban areas. ; Se presentan los resultados del análisis de la variabilidad climática asociada al ciclo ENOS para la Sabana de Bogotá. Para el análisis se tomaron los datos de anomalías de temperatura superficial del mar en las zonas EN 1+2, 3, 4 y 3+4 del Pacífico tropical, la temperatura media mensual del aire y de precipitación mensual. Se identificó una relación inversa entre las anomalías de TSM y la precipitación: condiciones cálidas (anomalías positivas de TSM) reducen la precipitación regional, mientras que las condiciones frías ...
