Ideam reports the start of the "rainiest" season in Colombia: What to expect?
Despite an atypical first quarter, marked by precipitation well above the historical average for the December-March season, the Institute of Hydrology, Meteorology and Environmental Studies (Ideam) warned that for the remainder of the month and until mid-June 2026, the country will face the first rainiest season of the year.

TL;DR
- Colombia is entering its first rainy season of the year, expected to last until mid-June 2026.
- March will see above-normal rainfall in many inter-Andean valleys, piedmonts, and specific departments like La Guajira, Córdoba, Sucre, Bolívar, and Magdalena.
- While April and May might see a slight decrease in intensity or frequency, they are still considered part of the rainiest season.
- Ideam is monitoring the situation and collaborating with the National Disaster Risk Management System.
- International climate models suggest conditions favorable for the return of the El Niño phenomenon in the second half of 2026, after two years of absence.
