Madrid or New York: which climate?
Madrid (Spain) has a hot-summer mediterranean climate, whereas New York (United States) has a hot-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 New York.
Madrid is warmer than New York by 2.1 °C in annual average: 14.2 °C against 12.1 °C.
New York gets more rain than Madrid: 1,098 mm per year against 430 mm.
Madrid gets 10.3 hours of sunshine per day on average, against 8.8 hours in New York.
Madrid has warmed by +2.4 °C between 1940 and 2025, against +1.7 °C in New York. Madrid is therefore warming faster than New York. Both trends are statistically significant.
Madrid averages 65 hot days (≥ 30 °C) and 39 frost days per year; New York averages 20 and 75.

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.
