October is often part of the second major rainy season for the Andes and Amazon with frequent showers and higher humidity. Rivers can rise, affecting boat routes and remote-access logistics.

Average temperature across Colombia in October.
Cartagena, Santa Marta, Barranquilla, Rosario Islands
October can be unsettled with wide swings between bright sunlight and passing tropical downpours; humidity is high and the sea can be choppy, though major storms rarely make landfall directly in Colombia. This is outside the core tourist season, so you’ll find good deals but must accept more weather-related unpredictability. Pack a waterproof daypack and keep flexible plans for island visits.
Nuquí, Bahía Solano, Quibdó
October is still within the heavy-rain period but remains prime for whale watching before the season winds down; marine trips can be exhilarating when seas cooperate. Inland trails are slippery and some secondary air services change schedules regularly, so allow slack in travel plans. The incredible rainforest humidity and near-constant green make it unforgettable for wildlife enthusiasts despite logistical challenges.
Bogotá, Medellín, Coffee Triangle, Cali
October can be one of the wettest months in the higher Andes with regular heavy showers and cloud banks that reduce mountain visibility - Nevado trekking may be limited to clear days. Colombia’s cities still offer cultural attractions unaffected by the weather, but plan interior travel with extra time. The coffee landscapes are spectacularly green; lodge stays are quieter and often more personalized.
Eastern Plains
October advances the dry transition with increasing accessibility by road; grasslands brown as water recedes and terrestrial wildlife becomes easier to find on foot or horseback. Dust returns to tracks; bring sunglasses and a dust mask for open-vehicle rides. Lodges start preparing for the busier dry season, and bookings pick up for November-March.
Leticia, Puerto Nariño, Amacayacu
October sees rising waters again in many tributaries and heavier rainfall, which expands flooded forests and brings seasonal fish migrations closer to river communities. Connectivity can be slower as villagers adapt travel by canoe; lodges remain open but calibrate schedules. Bring protective clothing for long wet days and good insect protection for night outings.
There are no major festivals or events in Colombia during October to be aware of.
