Berlin or Miami: which climate?
Berlin (Germany) has a warm-summer humid continental climate, whereas Miami (United States) has a tropical savanna climate, according to the Köppen-Geiger classification.
The values compared here are normals computed over 86 complete calendar years, from 1940 to 2025, using ERA5 reanalysis data from the Copernicus programme. The same method and the same period apply to Berlin and to Miami.
Miami is warmer than Berlin by 15.2 °C in annual average: 24.4 °C against 9.2 °C.
Miami gets more rain than Berlin: 1,041 mm per year against 606 mm.
Miami gets 10.6 hours of sunshine per day on average, against 7.5 hours in Berlin.
Berlin has warmed by +2.4 °C between 1940 and 2025, against +1.0 °C in Miami. Berlin is therefore warming faster than Miami. Both trends are statistically significant.
Berlin averages 6 hot days (≥ 30 °C) and 75 frost days per year; Miami averages 45 and 0.

A difference is only reported when it exceeds the resolution of the data. ERA5 is a reanalysis on a grid of about 31 km: two nearby cities often fall in the same cell, and below half a degree you are reading the grid, not the climate.
