Madrid or Oslo: which climate?
Madrid (Spain) has a hot-summer mediterranean climate, whereas Oslo (Norway) 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 Madrid and to Oslo.
Madrid is warmer than Oslo by 9.2 °C in annual average: 14.2 °C against 5.0 °C.
Oslo gets more rain than Madrid: 940 mm per year against 430 mm.
Madrid gets 10.3 hours of sunshine per day on average, against 7.5 hours in Oslo.
Oslo has warmed by +2.8 °C between 1940 and 2025, against +2.4 °C in Madrid. Oslo is therefore warming faster than Madrid. Both trends are statistically significant.
Madrid averages 65 hot days (≥ 30 °C) and 39 frost days per year; Oslo averages 0 and 148.

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.
