Visitor season
Low season. May averages 33% of August's overnight stays per day. More overnight stays than April.
Overnight stays across Cantabria do not measure queues, day visitors or congestion at individual sights. For its size, busier than most of Europe this month.
Hotel price season
A little below usual. Historical regional hotel revenue (2024–2025 monthly average): €78 per occupied room-night. An average, not a booking quote.
Fewer overnight stays do not automatically mean cheaper rooms. Check actual quotes for your trip.
The historical regional amount comes from INE Spain, EOH/IRSH table 2059: hotel average daily rate per occupied room; the country price level is national. Hotel averages are not live booking quotes.

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 Spain, EOH/IRSH table 2059: hotel average daily rate per occupied room). Full method · this region's data.
