Where the figures come from

Deer Valley's temperatures are measured 82 km from the centre, at Evanston.

Deer Valley's station stands 297 m below the city centre, so the centre is likely a little cooler than the figures say.

Deer Valley 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. Deer Valley: 1999-2020 (rainfall 1991-2020) normals, Evanston (81.9 km from centre). San Juan: 1991-2020 normals, San Juan / Int., Puerto Rico (12.8 km from centre).
