Methodology & sources

Mexico City

Temperature & precipitation — the official 1991–2020 climate normals from CONAGUA / SMN, Mexico's national weather service, measured at Playa Caleta 454 Colonia Marte, about 5 km from the city centre.

Cloud, humidity, wind & sunshine — modelled estimates from NASA POWER, NASA's satellite-and-reanalysis climatology. This is the standard global source for atmospheric variables, which are not measured at most weather stations.

Three Rivers

Temperature & precipitation — 1991–2020 normals computed from 29 years of daily observations at Ash Mtn, a weather station, about 9 km from the city centre. The underlying daily records come from NOAA's global station network.
