In April 2026, Basel recorded 61,619 arrivals and 116,148 overnight stays, a decrease from the previous year when arrivals were 64,214 and overnight stays were 123,551. This represents a drop of roughly 4% in arrivals and 6% in overnight stays compared to April 2025. The number of available rooms also fell to 137,640 from 141,744, while occupied rooms decreased slightly to 79,615 from 80,909. The average stay duration remained stable at 1.9 nights.

The domestic market was the largest contributor, with Swiss visitors accounting for 39.8% of all overnight stays, followed by Germany at 15.3% and the United States at 8.8%. The share of domestic stays is notably high, suggesting a strong reliance on local tourism during this period. The decline in international arrivals may reflect broader travel trends or specific factors affecting inbound tourism to Basel in April 2026.

Hotel occupancy rates, calculated as occupied rooms divided by available rooms, stood at approximately 57.8% for April 2026, down from 57.1% in April 2025. This slight increase in occupancy despite fewer total arrivals indicates that hotels may have reduced capacity or that visitors stayed in fewer but more fully utilized properties. Without data broken down by hotel category, it is not possible to assess differences between luxury, mid-range, or budget segments.

The data does not explicitly indicate seasonal effects or special events, but the decline in arrivals and overnight stays compared to the previous year suggests that April 2026 was a weaker month for tourism in Basel. The consistent average stay duration implies that visitor behavior regarding length of trip has not changed significantly.
