Has the climate in Guelma changed?

Guelma has warmed about 5.9°F between 2002 and 2024.

About 2.7°F per decade, measured from Guelma's official daily weather records, 2002–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Guelma's climate has warmed faster than most other cities in Algeria.

Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.

In day-to-day terms, that long-term shift shows up as about 4 more freezing nights a year and about 59 more days above 90°F compared with the 1970s.

Methodology & sources

Temperature — 1991–2020 normals computed from 12 years of daily observations at Guelma, a weather station, about 4 km from the city centre. The underlying daily records come from NOAA's global station network.
