Paris is projected to shift from Cfb to Cfa by the 2071–2099 window (SSP2-4.5).

Methodology & sources

Paris

Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Orly, a weather station, about 15 km from the city centre. The underlying daily records come from NOAA's global station network.

Cloud, humidity, wind & sunshine — modelled estimates from NASA POWER, NASA's satellite-and-reanalysis climatology. This is the standard global source for atmospheric variables, which are not measured at most weather stations.

Castries

Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.

Precipitation — 1991–2020 normals computed from 10 years of daily observations at LE Lamentin, a weather station, about 66 km from the city centre. The underlying daily records come from NOAA's global station network.
