Has the climate in Odienné changed?

Odienné has warmed about 0.8°F between 1977 and 2020.

About 0.4°F per decade, measured from Odienné's official daily weather records, 1977–2020. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Odienné's warming is broadly in line with other cities in Côte d'Ivoire — 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 16 fewer days above 90°F compared with the 1970s.

When in the year the change shows up
