Where the figures come from
Keystone's temperatures are measured 51 km from the centre, at Leadville / Stringtown.
Keystone's station stands 232 m above the city centre, so the centre is likely a little warmer than the figures say.
Keystone 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. Keystone: 2006-2020 (rainfall 1991-2020) normals, Leadville / Stringtown (50.8 km from centre). San Juan: 1991-2020 normals, San Juan / Int., Puerto Rico (12.8 km from centre).
