Prague or Toulouse: which climate?
Prague (Czechia) has a warm-summer humid continental climate, whereas Toulouse (France) has a temperate oceanic 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 Toulouse.
Toulouse is warmer than Prague by 4.5 °C in annual average: 13.3 °C against 8.8 °C.
Toulouse gets more rain than Prague: 782 mm per year against 647 mm.
Toulouse gets 8.8 hours of sunshine per day on average, against 7.9 hours in Prague.
Prague has warmed by +2.5 °C between 1940 and 2025, against +2.0 °C in Toulouse. Prague is therefore warming faster than Toulouse. Both trends are statistically significant.
Prague averages 6 hot days (≥ 30 °C) and 89 frost days per year; Toulouse averages 22 and 27.

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.
