Has the climate in Mostar changed?

Mostar has warmed about 4.4°F since 2002.

About 2.3°F per decade, measured from Mostar's official daily weather records, 2002–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Mostar's climate has warmed faster than most other cities across Europe.
