Where the figures come from

Cardiff 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.

Cardiff's sunshine is measured 83 km from the centre, at Lyneham.

Temperature and rainfall are climate normals, averaged over the years shown. Cardiff: 1991-2020 normals, Cardiff-Wales Airport (14.9 km from centre). Hoi An: 1991-2020 normals, Da Nang (23.5 km from centre).
