Has the climate in Ilidža changed?

Ilidža has warmed about 4.6°F since 1971.

About 0.8°F per decade, measured from Ilidža's official daily weather records, 1971–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Ilidža's warming is broadly in line with other cities across Europe — neither unusually fast nor unusually slow.

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 10 fewer freezing nights a year and about 10 more days above 90°F compared with the 1970s.

Methodology & sources

Temperature — 1991–2020 normals computed from 30 years of daily observations at Sarajevo, a weather station, about 10 km from the city centre. The underlying daily records come from NOAA's global station network.
