Everything below is collected in one spot so you do not have to cross-check Cartagena climate: monthly averages by hand. The gap between Jan and Jun is 1.4 C here: 27.3 C against 28.7 C. No month dominates: the wettest is Oct at 7.81 mm/day, the driest Jan at 0.08 mm/day. Taken together that is roughly 1,363 mm of rain a year for the grid cell. Values come from a public open API; a successful result is cached so a later outage never blanks the page. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Cartagena climate table shows
Values are multi-decadal climatological averages for the 10.3982, -75.4933 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Is Cartagena climate data a forecast?
No. These are multi-decadal averages for the grid cell, not a prediction for any particular year.
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
