Where the figures come from

Vail's temperatures are measured 47 km from the centre, at Kremmling.

Vail's station stands 186 m below the city centre, so the centre is likely a little cooler than the figures say.

Vail 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. San Diego: 1991-2020 normals, San Diego International Airport (2.8 km from centre). Vail: 2006-2025 (rainfall 1991-2020) normals, Kremmling (46.5 km from centre).
