Setúbal has warmed about 1.6°F between 1971 and 2022.
About 0.3°F per decade, measured from Setúbal's official daily weather records, 1971–2022. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Setúbal's climate has warmed more slowly than most other cities in Portugal.

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.

Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
May has warmed the most — about 2.0°F. The warming runs across the whole year, not just one season.
