Has the climate in Antsirabe changed?

Antsirabe has warmed about 0.9°F between 1993 and 2024.

About 0.3°F per decade, measured from Antsirabe's official daily weather records, 1993–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

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

What has actually changed

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.

Methodology & sources

Temperature — 1991–2020 normals computed from 29 years of daily observations at Ivato, a weather station, about 128 km from the city centre. The underlying daily records come from NOAA's global station network.
