Weather in Medellín in January

A good month. January is a solid month to be in Medellín. You should expect rain on 20 days of the month, which is more days wet than dry.

Medellín barely has seasons. January 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.

Rain on 20 of the month's 31 days, 4 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 January reaches 30 °C. Across the twenty years measured, the hottest January day reached 29.9 °C and the coldest night fell to 13.6 °C, and the wettest single day dropped 110 mm — roughly 82% of the month's rain in one day.

January is moderately variable: 46 mm in the driest year against 290 mm in the wettest, around an average of 134 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 0.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 87% is the real story though — it is the number that decides how the day feels, not the 24.8 °C.

How January sits in the year

Temperatures hold steady either side: 24.1 °C in December, 24.8 here, 25.5 in February. Nothing about the timing within the month matters much.

Daylight in January

Medellín sits close enough to the equator that daylight barely moves all year — 11.8 hours in January, 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.

January in Medellín versus nearby

If Medellín is one option among several, the nearby comparison is worth making. Bogotá is a better bet in January — 5.2 °C cooler, 10 days less rain. Cali is close enough to be a coin toss — 5.4 °C warmer, 8 days less rain.

So: January 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.
