Where the figures come from

Mombasa 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. Mombasa: 1991-2020 normals, Mombasa (5.8 km from centre). San Diego: 1991-2020 normals, San Diego International Airport (2.8 km from centre).
