Weather in Barranquilla in July
Colombia · 20-year averages, July
A hard month. July is a hard month in Barranquilla, and worth planning around. You should expect rain on 18 days of the month, which is more days wet than dry.
July ranks 7 of 12 in Barranquilla: past the worst of the year but short of January, which is the month to book if the dates are open.
Rain on 18 days, 3 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 82% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: 24 days top 30 °C, making the heat continuous rather than occasional; the day barely swings — 4.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 34.1 °C and the coldest night fell to 23.8 °C, and the wettest single day dropped 108 mm — roughly 90% of the month's rain in one day.
This is the volatile part. July rainfall has ranged from 16 mm to 483 mm across the twenty years measured — a 467 mm spread around an average of 120 mm. The average is real but almost no individual July looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 13.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.
How July sits in the year
Temperatures hold steady either side: 30.9 °C in June, 30.8 here, 31 in August. Nothing about the timing within the month matters much. Rain is the thing that moves: August brings 5 days more of it, so the earlier half of a flexible trip is the safer half.
Daylight in July
Barranquilla sits close enough to the equator that daylight barely moves all year — 12.7 hours in July, 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 28.4 °C in July — warm enough that the water offers no relief from the heat. 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
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.
July 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, 5 days more rain. Medellín is a better bet in July — 5.9 °C cooler, 6 days more rain.
So: July is a compromise. January is 38 points better and is what Barranquilla is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
