Is September a good time?
September averages 73°F afternoons, with about 7 rain days. Later September is typically cooler.
Historical Ile-de-France regional averages, not a forecast or a measure of queues. Overnight demand compares average stays per day. This covers Paris and the whole Île-de-France region: Versailles, Disneyland Paris, Saint-Denis and the suburbs. Central Paris on its own is busier than these figures show, because the visitors concentrate there while the population count includes the whole region.

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. Full method · this region's data.
