Weather in Bogotá in September

A good month. September is a solid month to be in Bogotá. You should expect rain on 18 days of the month, which is more days wet than dry.

September ranks 3 of 12 in Bogotá. Only January scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 18 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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 September reaches 30 °C. Across the twenty years measured, the hottest September day reached 24.2 °C and the coldest night fell to 5.2 °C, and the wettest single day dropped 36 mm — roughly 35% of the month's rain in one day.

September is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest September on record still delivered 156 mm against 34 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 103 mm average is a reasonable planning figure, not a promise.

Wind is light at 4.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.

How September sits in the year

Temperatures hold steady either side: 19.2 °C in August, 19.7 here, 18.7 in October. Nothing about the timing within the month matters much. Rain is the thing that moves: October brings 6 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in September

Bogotá sits close enough to the equator that daylight barely moves all year — 12.1 hours in September, against a range of just 0.5 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: 11.9 °C between the year's warmest afternoons and coldest nights. At 2582 m, altitude is doing as much work here as latitude: thinner air means fierce sun by day and heat that leaves the moment it sets.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Bogotá versus nearby

If Bogotá is one option among several, the nearby comparison is worth making. Medellín is close enough to be a coin toss — 5.2 °C warmer, 7 days more rain. Cali is close enough to be a coin toss — 11.6 °C warmer, 7 days less rain.

So: September works, with January the better month by 15 points if the dates can move. If they cannot, nothing here should stop you booking.
