Has the climate in Herāt changed?
How Herāt's climate has changed
About 0.1°F per decade, measured from Herāt's official daily weather records, 2007–2020. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
What has actually changed
Each card compares the 1970s (the first ten years of the record) with recent years (the last ten) — the same span the headline and the chart use.
Herāt's temperature, year by year
Average temperature for each year from 2007 to 2020.
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 16 fewer freezing nights a year and about 20 fewer days above 90°F compared with the 1970s.
Methodology & sources
Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.
