Has the climate in Tarija changed?

Tarija has warmed about 1.1°F between 1991 and 2024.

About 0.3°F per decade, measured from Tarija's official daily weather records, 1991–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Tarija's warming is broadly in line with other cities across South America — 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 Capitan AV Oriel Lea Plaza Intl, a weather station, about 4 km from the city centre. The underlying daily records come from NOAA's global station network.
