Colombia braces for early, potentially intense El Niño event through 2027
Colombia’s environmental agencies have confirmed that the El Niño climate pattern has arrived three months ahead of forecasts and could become one of the strongest events recorded since 1950. The Ministry of Environment and the Institute of Hydrology, Meteorology and Environmental Studies (Ideam) estimate a > 95 % chance the phenomenon will persist through the second half of 2026 and into early 2027, with a 63 % probability of reaching “very strong” intensity between November 2026 and January 2027.
Projections indicate higher than average temperatures and significantly reduced rainfall across the Andean, Caribbean and Pacific regions. Expected consequences include heightened heat‑related health risks, reduced water availability, lower river and reservoir levels, decreased hydro‑electric generation, agricultural losses, and an elevated risk of forest fires. National and local authorities have issued alerts, urged water‑conservation measures, and called for activation of contingency plans.
In Bogotá, officials note that the Chingaza reservoir presently holds about 50 % of its capacity, offering more buffer than the 2024 drought, yet the city remains vulnerable because its water supply depends heavily on Andean páramo rains. The water utility highlights additional capacity at the Tibitoc plant, but warns that prolonged drought combined with higher consumption could again pressure reservoirs.
Overall, the government is coordinating with international bodies such as NOAA, urging communities and industries to adopt water‑saving practices and to prepare for possible restrictions as the El Niño episode unfolds.
