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.

San Sebastian's station stands 252 m above the city centre, so the centre is likely a little warmer than the figures say.

Temperature and rainfall are climate normals, averaged over the years shown. Killarney: 1991-2020 normals, Valentia Observatory (52.7 km from centre). San Sebastian: 1991-2020 normals, San Sebastian / Igueldo (6.1 km from centre).
