Has the climate in Eniwa changed?

Eniwa has warmed about 2.3°F between 1991 and 2024.

About 0.7°F per decade, measured from Eniwa'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? Eniwa's warming is broadly in line with other cities in Japan — 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.
