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.

In day-to-day terms, that long-term shift shows up as about 17 fewer freezing nights a year and about 2 more days above 90°F compared with the 1970s.

Methodology & sources

Temperature — 1991–2020 normals computed from 30 years of daily observations at Luxembourg Airport, a weather station, about 27 km from the city centre. The underlying daily records come from NOAA's global station network.
