In August 2026, Basel recorded 85,949 arrivals and 147,825 overnight stays. Compared to the same month in previous years, arrivals were about 7 percent lower than in August 2025, when 92,642 arrivals were recorded, but still higher than in August 2023 and August 2024. Overnight stays also declined by roughly 7 percent compared to August 2025, falling from 159,418 to 147,825, though they remained above the 2023 and 2024 levels. The average stay duration held steady at 1.7 nights.

Hotel occupancy showed a mixed picture. The number of available rooms decreased to 140,678, the lowest August figure since 2023, while occupied rooms fell to 90,221. This resulted in an occupancy rate of about 64 percent, down from 65 percent in August 2025 but similar to the 60 percent seen in August 2023. The decline in occupied rooms was less steep than the decline in arrivals, suggesting that guests who did visit stayed slightly longer or that group bookings offset individual traveler declines.

Switzerland remained the largest source market, accounting for 33.4 percent of all overnight stays with 49,311 nights. Germany followed with 14.4 percent, the United States with 8.1 percent, the United Kingdom with 5.7 percent, and the Netherlands with 4.5 percent. The category “Other” made up 33.9 percent of overnight stays, indicating a broad and diverse mix of smaller source markets. Compared to the strong August 2025, the decline appears broadly distributed rather than driven by a single country, though the data does not provide monthly comparisons by country for earlier months.

The lower August 2026 figures may reflect a return to more typical seasonal patterns after an unusually strong August 2025. No specific events or anomalies are evident from the provided data, but the reduction in available rooms suggests some temporary capacity constraints or hotel renovations may have influenced the overall numbers.
