Weather in Barranquilla in January

Prime time. January is about as good as Barranquilla gets. Highs average 30.2 °C, lows 25 °C, and rain falls on 0 days — nothing in the month is working against you.

January is the highest-scoring month of the twelve. The nearest rival is February, and the month at the other end of the year is August.

Rain is not a factor worth planning around this month. Pack for 30.2 °C days and 25 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 18 days top 30 °C — hot spells arrive, but they break; the day barely swings — 5.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 33 °C and the coldest night fell to 22.8 °C.

January is dependably dry, and that reliability is the point: across the twenty years measured, the wettest January on record still only managed 13 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Januarys brought 2 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind sits around 19.3 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How January sits in the year

Temperatures hold steady either side: 30.1 °C in December, 30.2 here, 30.6 in February. Nothing about the timing within the month matters much. Rain has already shifted: 6 days fewer than December had.

Daylight in January

Barranquilla sits close enough to the equator that daylight barely moves all year — 11.5 hours in January, against a range of just 1.3 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 26.7 °C in January — warm enough to stay in as long as you like. The sea peaks at 29.2 °C in October and bottoms out at 26.4 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

January in Barranquilla versus nearby

If Barranquilla is one option among several, the nearby comparison is worth making. Cartagena is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Medellín is the weaker option in January — 5.4 °C cooler, 20 days more rain.

So: January is the answer for Barranquilla. If it is booked out or priced out, February is the next best thing at 2 points behind, and August is the month to keep off the shortlist.
