Where the figures come from

Key West's temperatures are measured 69 km from the centre, at Key West Airport.

Key West 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. Busan: 1991-2020 normals, Pusan (9.7 km from centre). Key West: 1991-2020 normals, Key West Airport (69.1 km from centre).
