Naples or Paris: which climate?
Naples (Italy) has a hot-summer mediterranean climate, whereas Paris (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 Naples and to Paris.
Naples is warmer than Paris by 6.0 °C in annual average: 16.9 °C against 10.9 °C.
Naples gets more rain than Paris: 1,099 mm per year against 674 mm.
Naples gets 10.2 hours of sunshine per day on average, against 7.7 hours in Paris.
Paris has warmed by +1.8 °C between 1940 and 2025, against +1.4 °C in Naples. Paris is therefore warming faster than Naples. Both trends are statistically significant.
Naples averages 0 hot days (≥ 30 °C) and 0 frost days per year; Paris averages 6 and 44.

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.
