Where the figures come from

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. Mazatlan: 1991-2020 normals, Colonia Juan Carras-Co Mazatlan, Sin. (2 km from centre). Siena: 2006-2017 (rainfall 1991-2020) normals, Arezzo (45 km from centre).
