Where the figures come from

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. Galle: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km. Istanbul: 1991-2020 normals, Istanbul / Goztepe (9.9 km from centre).
