Bahía Blanca has warmed about 0.6°F between 1971 and 2024.
About 0.1°F per decade, measured from Bahía Blanca's official daily weather records, 1971–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Bahía Blanca's climate has warmed more slowly than most other cities in Argentina.
