December weather at a glance, starting with the beach: where the sea is still warm, the sky is clear and the rain has stopped. Every figure is a long-term monthly average from ERA5 climate data, the same numbers you can explore on the Leidora climate map.
Ranked by Leidora's beach score, the one the map shows: sea temperature 35%, afternoon air 30%, rain 20%, clear sky 15%. One weak part pulls the whole score down, so a hot, sunny coast with a cold sea does not make the list. Only places rated Good (60+) or better are shown, at most two per country: the world's best 15 under All, and up to 10 for each continent. Day is the afternoon high at the shore: the grid's daily maximum runs 1–3 °C cool on the coast, as 151 weather stations measured, so it is corrected as the score corrects it.
