How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates. Sunshine is shown relative to the city's own year (modelled data overstates absolute hours).Heat and sea: days with a high of 30 °C or more are averaged over 2016–2025 (ERA5); sea-surface temperature is the monthly mean 2022–2025 at the nearest open-sea grid point within about 20 km (Open-Meteo Marine).Crowds:Relative to an average month in the same region (Eurostat nights spent at tourist accommodation, by NUTS 2 region and month) — a measure of season, not of how crowded one city is compared with another. Busiest month August, quietest January; NUTS 2 region FRJ1, 2022–2025, Eurostat.
