Has the climate in Īlām changed?

Īlām has warmed about 5.1°F between 1971 and 2024.

About 0.9°F per decade, measured from Īlām'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? Īlām's warming is broadly in line with other cities in Iran — 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 23 fewer freezing nights a year and about 4 more days above 90°F compared with the 1970s.

Methodology & sources

Temperature — 1991–2020 normals computed from 29 years of daily observations at Kermanshah, a weather station, about 95 km from the city centre. The underlying daily records come from NOAA's global station network.
