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.

Siena's temperatures are measured 45 km from the centre, at Arezzo.

Siena 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.

Temperature and rainfall are climate normals, averaged over the years shown. Rio de Janeiro: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km. Siena: 2006-2017 (rainfall 1991-2020) normals, Arezzo (45 km from centre).
