Low season. September averages 33% of August's overnight stays per day. Fewer overnight stays than August.
Overnight stays across Molise do not measure queues, day visitors or congestion at individual sights. For its size, quieter than most of Europe this month.
Hotel price season
A little above usual. The regional index has no room-rate baseline in euros.
Fewer overnight stays do not automatically mean cheaper rooms. Check actual quotes for your trip.
The hotel-season index is regional (ISTAT, NIC consumer price index for accommodation services (ECOICOP 112), by region); the country price level is national. Neither is a room quote.

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 (ISTAT, NIC consumer price index for accommodation services (ECOICOP 112), by region).
