Oviedo has warmed about 3.1°F between 1973 and 2023.
About 0.6°F per decade, measured from Oviedo's official daily weather records, 1973–2023. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Oviedo's warming is broadly in line with other cities in Spain — neither unusually fast nor unusually slow.

not a straight climb.

Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
