That means about 40,000 overnight visitors on a typical December night across the region, 26% of them from Portugal itself. Rentals booked through Airbnb, Booking, Expedia and Tripadvisor add up to 22,000 more: 55 for every 100 counted above. Some are the same properties counted twice.

Crowds: Eurostat nights spent at tourist accommodation, by month and NUTS 2 region, 2024–2025 average. Overnight visitors per night is the month's nights divided by its days; the per-1,000 figure is Eurostat's, against each year's population. Platform rentals: Eurostat nights booked via Airbnb, Booking, Expedia and Tripadvisor, 2024–2025 average, shown separately because some properties are in both counts. Weather: Holiday Climate Index computed from ERA5 reanalysis with daily highs, night lows and rain days corrected from open national weather-service station records, 2011–2025, population-weighted to the region; day-by-day figures are the same data averaged by date. Heat and rain odds are counted across those years. Sunrise and sunset: NOAA solar equations, local time. Prices: Eurostat price level index and HICP, national; the first figure is regional (INE Portugal, Inquérito à Permanência de Hóspedes: hotel room revenue per guest-night).
