As a result of climate change, an increase in frequency has been established at the extremes of the El Niño-Southern Oscillation (ENSO) phases. For Colombia, ENSO represents significant changes in average climate patterns, generating extreme weather conditions. Knowing the behavior of extreme temperature values is fundamental for agricultural planning, forest fire management, public health, land management, among others. In this study annual series of fifteen (15) Extreme Temperature Indices (ETI) were built, using information from climatology in-situ stations of Colombia with records in 1987-2021 period. Then, mid-term changes (MTC) in ETI were assessed, and those MTC were compared against ETI forced by the extreme phases of ENSO (Warm phase or El Niño years NOY, and cold phase or La Niña years NAY), regarding the neutral or normal phase NOR. The ITE's mid-term significant changes, and the ITE's significant anomalies during ENSO extreme phases, were assessed using the nonparametric Mann-Whitney-Wilcoxon test (MWW). Among the results, it is highlighted that for the ETI there were positive temperature anomalies during El Niño years and negative anomalies during La Niña years. In addition, trends as marked as the anomalies observed during the ENSO phases were not observed for the MTC, nonetheless, the positive changes of the ETI were the most recurrent.
