Is River Cruise at long term risk from climate change?

Climate change may make low-water disruptions more frequent for European river cruises, but the industry possesses enough adaptability to prevent a long-term threat to its sustainability, according to Bernstein analysts. In 2026, record or near-record low water levels on the Rhine and Danube rivers compelled operators to modify itineraries, switch ships, and cancel certain sailings, according to Bernstein's research note.

These analysts attributed the issue to rising temperatures, which were reducing snowpack, hastening snowmelt, and intensifying evaporation, while also causing a gradual decline in summer Rhine flows. The problem, they noted, stemmed from water arriving earlier in the year and evaporating more quickly during hotter periods, rather than Europe receiving less water overall.

Climate projections indicated ongoing warming, increased evapotranspiration, earlier snowmelt, diminishing Alpine glaciers, and potentially lower summer precipitation, which suggested heightened susceptibility to drought and low-water occurrences, said Bernstein. However, operators could alleviate these risks by reallocating capacity to other rivers or ocean cruising, adjusting sailings away from the most at-risk summer months, enhancing land-based alternatives, and employing shallower-draft vessels, said the analysts.

Viking's (IS:VKING) exposure is already evolving, with only 21% of its present orderbook featuring traditional Rhine and Danube longships, while future growth is anticipated to stem predominantly from ocean cruising and other river systems, according to Bernstein. The company can also lengthen the river-cruise season into February, March, and November, potentially compensating for capacity lost during periods of heightened summer vulnerability, the analysts suggested.

They pointed out that Viking's Elbe operations already circumvent late July and August and utilize ultra-shallow-draft vessels and land-based alternatives to manage recurrent low-water conditions. While low-water disruptions are expected to become more common, the analysts concluded that diversification, seasonal shifts, contingency planning, and engineering solutions should bolster the industry's long-term resilience.
