Prague or Stockholm: which climate?
Prague (Czechia) has a warm-summer humid continental climate, whereas Stockholm (Sweden) has a warm-summer humid continental 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 Prague and to Stockholm.
Prague is warmer than Stockholm by 2.4 °C in annual average: 8.8 °C against 6.4 °C.
Prague gets more rain than Stockholm: 647 mm per year against 562 mm.
Prague has warmed by +2.5 °C between 1940 and 2025, against +1.9 °C in Stockholm. Prague is therefore warming faster than Stockholm. Both trends are statistically significant.
Prague averages 6 hot days (≥ 30 °C) and 89 frost days per year; Stockholm averages 0 and 118.

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.
