When does it rain in Colombia in 2026?

Bogotá and Medellín commonly show two wetter stretches and two drier stretches across the year, a pattern often called bimodal. Wet months concentrate showers and grey afternoons; dry months bring more outdoor café weeks without changing the city’s base temperature much: Living in Bogotá and Living in Medellín. Cali and coffee-region towns share Andean rain logic with their own local peaks. Afternoon storms are a practical habit: carry a compact shell even when the morning looks bright.

Amazon and Pacific edges can run much wetter and follow different calendars. Most first-year movers in the big four cities should treat those rainforest patterns as travel weather, not lease weather. Follow IDEAM (Colombia’s national meteorology agency) city pages rather than a single national “rainy season” slogan: Weather in Colombia.

Cartagena, Barranquilla, and Santa Marta keep tropical heat while rainfall rises and falls. Many guides describe a wetter Caribbean window from about May through November and sunnier stretches in the drier months: Living in Cartagena. Humidity stays high even when showers pause, so rain planning and AC planning travel together: Altitude and climate and Utilities, internet, and transport.

For movers, wet months mean TransMilenio or Metro crowds, slower hillside traffic in Medellín, mould risk in poorly ventilated flats, and fewer outdoor weekend escapes. Keep a small dehumidifier or better ventilation in Cartagena and older Bogotá walk-ups if walls stay damp. Dry months favour Guatapé day trips and plaza life. Climate shortlist still starts with comfort vetoes: Best climate. Do not schedule your only housing hunt for the wettest week if you can avoid it; flooded streets and grey viewings distort judgment.
