Weather in Cali in January
Colombia · 20-year averages, January
Shoulder season. January is shoulder season in Cali — cheaper, quieter, and a genuine gamble. The heat itself is manageable at 30.2 °C, but 84% humidity is what you will actually feel.
January ranks 5 of 12 in Cali: past the worst of the year but short of August, which is the month to book if the dates are open.
Rain on 12 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Natural fibres and a second shirt for the day. At 84% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: 17 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest January day reached 35.3 °C and the coldest night fell to 17 °C, and the wettest single day dropped 28 mm — roughly 50% of the month's rain in one day.
January is moderately variable: 9 mm in the driest year against 134 mm in the wettest, around an average of 56 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.
Wind is light at 4.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.
How January sits in the year
Temperatures hold steady either side: 29.5 °C in December, 30.2 here, 30.6 in February. Nothing about the timing within the month matters much.
Daylight in January
Cali sits close enough to the equator that daylight barely moves all year — 11.9 hours in January, against a range of just 0.4 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: 10.8 °C between the year's warmest afternoons and coldest nights. At 758 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
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
January in Cali versus nearby
If Cali is one option among several, the nearby comparison is worth making. Bogotá is a better bet in January — 10.6 °C cooler, 2 days less rain. Medellín is close enough to be a coin toss — 5.4 °C cooler, 8 days more rain.
So: January is effectively as good as it gets here — 6 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
