Best time to visit Cartagena

January is the best month in Cartagena, scoring 87 out of 100, with August the weakest at 50. The 37-point spread means timing is worth planning around without being decisive. The good window runs January to March — 3 months within ten points of the best.

March is the warmest month at 30.4 °C and October the coolest at 29 °C — a 1.4 °C spread across the year. 158 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season.

There is a real wet season here. May to October carry the rain — up to 27 wet days in a month — while January, February, March and December drop as low as 1. That 26-day gap is the biggest single difference between a good month and a bad one in Cartagena, and it moves further than the temperature does.

The sea never drops below 27.1 °C, so swimming is on the table year round. Daylight barely moves: about 12.7 hours whatever the month, which removes one variable from the decision entirely.

The three strongest months are January, February, March. The one to think twice about is August. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
