About 0.5°F per decade, measured from Avilés'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? Avilés's warming is broadly in line with other cities in Spain — neither unusually fast nor unusually slow.
What has actually changed
Each card compares the 1970s (the first ten years of the
record) with recent years (the last ten) — the same span
the headline and the chart use.

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.
April has warmed the most — about 1.7°F. The warming runs across the whole year, not just one season.
Methodology & sources
Temperature — 1991–2020 normals computed from 30 years of daily observations at Asturias/aviles, a weather station, about 10 km from the city centre. The underlying daily records come from NOAA's global station network.
