About this data

All figures are 25-year averages (January 2001 – December 2025) from the NASA POWER project. Temperature, humidity, wind and precipitation come from the MERRA-2 reanalysis (precipitation is the bias-corrected MERRA-2 product), cloud and solar values from CERES satellite data. They describe a grid cell of roughly 50–70 km, not a single weather station. So they can differ from airport records. The gaps are largest on coasts, in mountains and for rainfall. Average highs and lows are the monthly mean temperature plus/minus half of the average daily temperature range. Counts of rainy days are not part of this dataset.

The grid cell’s average elevation is 124 m, while Cartagena lies at about 1 m. Temperatures on this page were therefore adjusted by +0.8 °C1.4 °F using the standard lapse rate of 6.5 °C per 1,000 m.
