Where the figures come from

Siem Reap 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. San Francisco: 1981-2010 normals, Alameda Naval Air Station (9.1 km from centre). Siem Reap: 2001-2020 normals, NASA POWER reanalysis grid, no weather station within 90 km.
