Crowds: Eurostat nights spent at tourist accommodation establishments by month and NUTS 2 region, per 1,000 inhabitants, divided by days in the month. "Season here" is the month's figure as a share of this region's busiest month. "Visitors" ranks overnight visitors per resident against all Europe's regions that month. Weather: Holiday Climate Index (Scott et al. 2016; Rutty et al. 2020) computed from ERA5 reanalysis with daily highs, night lows and rain days corrected from open national weather-service station records and population-weighted to the region. Prices are regional where the page says so (Statistics Finland, StatFin 11ix: average room price per occupied room (incl. VAT)), otherwise national.
