Evolution
First semester of 2016
Equatorial Pacific Ocean: El Niño reached its maximum development (2.5 ° C) between November and December 2015 and dissipated during the first half of 2016, giving way to normal conditions in June. The cooling of the ocean surface began in July, which would facilitate the formation of a La Niña phenomenon in the fourth quarter of the year, whose probability of occurrence is between 55% and 60%.
Cauca River Valley: the climatic anomalies that characterized the year 2015 were attenuated and the climatic variables gradually returned to normal values or close to these. In fact, in June only the average daily temperature oscillation showed a very high value; the other variables presented normal values, a little high or a little low.
