Has the climate in Chimbote changed?

Chimbote has warmed about 3.1°F between 1973 and 1997.

About 2.4°F per decade, measured from Chimbote's official daily weather records, 1973–1997. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Chimbote's climate has warmed faster than most other cities in Peru.
