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.

Galle has no weather station within reach, so its figures come from a gridded climate model rather than a measured record, and read a broad area rather than the city itself.

Temperature and rainfall are climate normals, averaged over the years shown. Cardiff: 1991-2020 normals, Cardiff-Wales Airport (14.9 km from centre). Galle: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km.
