In March 2026, Basel's tourism activity showed a mixed performance compared to previous years. Arrivals reached approximately 64,700, marking a new high for the month and continuing an upward trend from 2023. However, overnight stays totaled around 117,800, which represents a decrease of roughly 6% from the previous year's peak, though it remains above the levels seen in 2023 and 2024. The average stay duration declined to 1.8 nights, the lowest in the four-year period.

Hotel occupancy rates improved, with approximately 86,700 rooms occupied out of 141,700 available, resulting in an occupancy rate near 61%. This is a notable increase from 2024, driven by higher occupancy despite a slightly lower room inventory. The data indicates more efficient room utilization compared to the previous year, even with fewer total overnight stays.

The primary source markets for overnight stays remained consistent. Domestic visitors from Switzerland were the largest contributor, accounting for 37% of all overnight stays. Germany followed as the second-largest market with a 17.3% share. The United States, the United Kingdom, and France rounded out the top five. The distribution among these key markets appears stable, with no major shifts indicated from the provided data.

The seasonal pattern for March appears normal, with no evident anomalies or special events drastically altering the trends. The key development is the divergence between record arrivals and a moderate pullback in overnight stays and average length of stay, suggesting a shift toward shorter visits.
