Weather in Medellín in October
Colombia · 20-year averages, October
A good month. October works. It is not the peak, but nothing about it fights you. You should expect rain on 27 days of the month, which is more days wet than dry.
Medellín barely has seasons. October scores 65 out of 100 against a best of 67 in February — a gap small enough that the month you choose matters far less here than the week you choose. Worth keeping in perspective: October is the weakest month of Medellín's year and it is still a perfectly good one. The downside here is small.
Rain on 27 of the month's 31 days, 8 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average October reaches 30 °C. Across the twenty years measured, the hottest October day reached 28.7 °C and the coldest night fell to 14.6 °C, and the wettest single day dropped 81 mm — roughly 35% of the month's rain in one day.
October is one of the reliable ones — rainfall has stayed between 164 mm and 329 mm across all twenty years, a narrow enough band that the 232 mm average is something you can plan against rather than merely quote.
Wind is light at 0.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 90%, high enough to notice on the warm days without dominating them.
How October sits in the year
Temperatures hold steady either side: 24.9 °C in September, 23.9 here, 23.6 in November. Nothing about the timing within the month matters much.
Daylight in October
Medellín sits close enough to the equator that daylight barely moves all year — 12 hours in October, against a range of just 0.7 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
An inland climate
Despite being inland, the year stays fairly even: 8.5 °C between the year's warmest afternoons and coldest nights. At 1405 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.
How busy it gets
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
October in Medellín versus nearby
If Medellín is one option among several, the nearby comparison is worth making. Bogotá is close enough to be a coin toss — 5.2 °C cooler, 3 days less rain. Cali is the weaker option in October — 6.2 °C warmer, 7 days less rain.
So: October is effectively as good as it gets here — 2 points behind February, which is inside the margin where the weather stops being the deciding factor and price starts being it.
