Where the figures come from
Cairns's temperatures are measured 27 km from the centre, at Green Island Aws.
Cairns has no rain gauge within 25 km of the centre, so its rainfall comes from a gridded climate dataset read at the city rather than from a gauge further away.
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. Cairns: 1993-2010 (rainfall 1991-2020) normals, Green Island Aws (27 km from centre). Rio de Janeiro: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km.
