Methodology & sources

Temperature & precipitation — the official 1991–2020 climate normals from INMET, Brazil's national meteorological institute, measured at Belem, about 8 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.
