Danube and Rhine low water cripple European river traffic

Danube low water Rhine low water European river transport cargo capacity reduction cruise cancellation

Extreme heat and prolonged drought have pushed water levels on Europe’s major rivers to record lows. In Budapest the Danube fell to 31 cm in the morning and further to 28 cm in the afternoon – the lowest measurements since 25 Oct 2018. Similar historic lows are reported on the Danube’s Serbian and Croatian stretches, where historic shipwrecks have become visible.

The shallow water has forced about 15 cruise ships to wait on the Hungarian Danube and has reduced cargo‑ship capacity to roughly 10‑20 % of normal loads. Uniworld Boutique River Cruises cancelled its August 2, 2026 Danube cruise aboard the S.S. Emilie, offering full refunds or a 20 % re‑booking discount. Hungarian authorities have declared a state of extraordinary drought readiness, positioning pump barges at the Paks nuclear plant to safeguard cooling water supply.

On the Rhine, water at the Lobith gauge stood at 655 cm above NAP with a flow of 650‑700 m³/s, far below the usual 1 900 m³/s and approaching historic minima. The low level has raised transport costs for coal, oil products, iron ore and containers, and analysts warn it could shave 0.1‑0.2 % off Germany’s third‑quarter GDP.

Across both rivers, navigation authorities have not imposed formal restrictions; ship captains decide based on published depth data, with a safety rule that requires at least a 10‑cm clearance between a vessel’s keel and the riverbed.
