Where the figures come from
Killarney's temperatures are measured 53 km from the centre, at Valentia Observatory.
Killarney 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. Killarney: 1991-2020 normals, Valentia Observatory (52.7 km from centre). San Juan: 1991-2020 normals, San Juan / Int., Puerto Rico (12.8 km from centre).
