Five years is enough to rank communes against each other, not to describe a climate in absolute terms: a climate normal is computed over thirty. Values come from a gridded reanalysis, not a local weather station. Sunshine is given as an index rather than in hours: ERA5 infers it from irradiance and runs well above station measurements, but the bias is the same everywhere, so comparing communes remains sound.
