Where the figures come from
Rio de Janeiro has no weather station within reach, so its figures come from a gridded climate model rather than a measured record, and read a broad area rather than the city itself.
Temperature and rainfall are climate normals, averaged over the years shown. Osaka: 1991-2020 normals, Osaka (1.8 km from centre). Rio de Janeiro: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km.
