The heatwave nobody measures
The June 2026 European heatwave has caused significant drops in Rhine and Danube river levels, forcing barges to operate at approximately 50% capacity and triggering low-water surcharges, with knock-on delays cascading to major North Sea and coastal deep-sea ports. The inland waterway disruptions are expected to ripple through ocean shipping schedules as cargo backs up at port terminals awaiting reduced-capacity river transport.
