April marks the start of a principal rainy period for many Andean and Amazonian zones, with frequent heavy showers and higher river levels. Plan extra time for overland travel and be prepared for muddy trails in rural areas.

Average temperature across Colombia in April.
Cartagena, Santa Marta, Barranquilla, Rosario Islands
Humidity climbs in April as the first wet pulses arrive: short but intense showers begin to appear, especially inland toward the Sierra Nevada. Cartagena’s afternoons can alternate between blistering sun and refreshing downpours that quickly wash the streets; hotel pools are a welcome refuge. Travelers should expect occasional road slickness to Tayrona’s dirt trails and pack a light rain jacket and waterproof shoes.
Nuquí, Bahía Solano, Quibdó
April intensifies the rainfall across the Pacific slope - much of Chocó records some of the highest annual totals in the world - so rivers swell and waterfalls are spectacular. Water-based access becomes the norm for many lodges; plan extra travel time and anticipate occasional cancellations. For photographers and naturalists the rainforest is intoxicating, but torrential rains will limit long overland treks.
Bogotá, Medellín, Coffee Triangle, Cali
April is a classic start to the first rainy pulse across the Andean spine: Bogotá sees more sustained showers, and mountain trails in the Coffee Zone become muddier and slipperier. Medellín and lower-valley landscapes retain comfortable daytime warmth, though cloudbursts can interrupt outdoor plans. Easter/ Semana Santa brings domestic travel surges, so book transport early if visiting churches or colonial towns.
Eastern Plains
April marks the beginning of the Llanos’ wet season: rain returns in earnest, grasslands green up fast, and many dirt roads become impassable as rivers rise. Wildlife disperses and boat travel becomes the primary means to reach flooded savannahs and forest islands. Expect basic camps to adapt to wet conditions and plan extra travel time; waterproof gear is mandatory.
Leticia, Puerto Nariño, Amacayacu
April often hits a peak in river height and rainfall in many Amazon sectors, making canoe-based travel the primary means of accessing forest islands and research stations. Seasonal fruits and fish are plentiful and communities engage in busy river-based life. For travelers, the environment is immersive but wet: waterproof gear, sealed bags for electronics, and insect protection are non-negotiable.
There are no major festivals or events in Colombia during April to be aware of.
