Rankings across the 107 monitored cities, computed from the ERA5 (ECMWF/Copernicus) historical aggregates since 1940 and refreshed at every data recalculation. Just numbers, periods and a stated method.
Difference between the 1991–2020 climate normal and the 1961–1990 one: the top 10.
Where the change is smallest: the 5 cities with the lowest difference between the two normals (1991–2020 vs 1961–1990).
Linear-regression slope of the yearly means over the whole series, in degrees per decade: the top 10.
The most extreme daily highs and lows of the whole series (only cities with real max/min data).
Nights with a minimum ≥20°: yearly average over the last 5 full years, with the increase vs the 1961–1990 normal in parentheses.
Difference between average daily highs and lows (average of the last 5 full years): a more «continental» climate, with hot days and cool nights.
Where the day/night gap is smallest: often a sign of a mild, coastal or island climate.
