Where the figures come from

Copper Mountain's temperatures are measured 35 km from the centre, at Leadville / Stringtown.

Copper Mountain 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. Copper Mountain: 2006-2020 (rainfall 1991-2020) normals, Leadville / Stringtown (35.2 km from centre). Hoi An: 1991-2020 normals, Da Nang (23.5 km from centre).
