How this ranking works
Every country’s December is scored on three things: mean temperature, rainfall per day and sunshine hours, each averaged over ten years of ERA5 reanalysis. The score is the same one the map paints and the country pages print — a country cannot look better here than it does on its own page.
Countries that score identically are ordered by how far inside the comfortable range they sit, so a country in the middle of the band comes before one at its edge. Averages describe a typical December; they are not a forecast for the week you travel, and a national figure hides a lot in a large country — open a country to see its regions.
