Has the climate in Barranquitas changed?

Barranquitas has warmed about 1.2°F since 1971.

About 0.3°F per decade, measured from Barranquitas's official daily weather records, 1971–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Barranquitas's warming is broadly in line with other cities in Puerto Rico — 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.

When in the year the change shows up

How much warmer each month is now than in the 1970s. Useful if you garden or care about a particular season — otherwise the headline above already has the answer.
