Annaba has warmed about 2°F between 1973 and 2024.
About 0.4°F per decade, measured from Annaba's official daily weather records, 1973–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Annaba's climate has warmed more slowly than most other cities in Algeria.
