Executive Summary
The upper Danube is hovering just above its low‑water trigger, with minor falls projected during the coming week. Cruise itineraries remain mostly intact, but operators are quietly preparing ship‑swap plans in case the summer dry spell deepens.
Current Conditions
The Achleiten reference gauge near Passau reads 259 cm (normal navigable range 258–310 cm), indicating borderline low‑water conditions that still allow full‑draft sailing.1
Seven‑Day Outlook
Free‑flowing Wachau reach – Kienstock gauge
| Date | Level (cm) | Comment |
|---|---|---|
| Today (Jun 23) | 196 | Stable |
| +24 h | 182 | Light fall |
| +48 h | 193 | Rebound after storms |
| +72 h | 186 | Settling slightly below today |
No forecast exceeds seven‑day caution thresholds, and each value remains above the 164 cm low‑navigable benchmark for this reach.2
Three‑Week Risk Forecast
| Period | Likelihood of Disruption | Confidence |
|---|---|---|
| Days 1–7 | Caution | High. |
| Days 8–14 | Caution | Medium |
| Days 15–21 | Disruption | Low |
Persistent high‑pressure over Central Europe will keep rainfall sporadic, so any additional dip in levels will depend on whether scattered thunderstorms deliver meaningful runoff.3 Summer dryness historically sharpens after mid‑July, making Cancel‑For‑Any‑Reason coverage a prudent hedge.4
Cruise‑Line Responses
Spokesperson for Emerald Cruises reports that operational teams are already adjusting embarkation points and lining up sister‑ship swaps to work around shallow spots between Passau and Melk.5
President of Avalon Waterways states that, while only minor port substitutions are forecast this week, the line will not hesitate to cancel or reroute Lower Danube sailings if depths drop below safe margins, echoing its proactive stance during last year’s high‑water event.6
An Adept Traveler analyst notes that most major brands keep identical vessels running opposite directions, allowing rapid mid‑river passenger transfers should any segment become impassable.7
Traveler Advice
Plan for possible bus segments, especially on itineraries starting or ending in Passau. Leave generous buffer time before onward flights, because last‑minute pier changes often lengthen transfer drives.
Pack light and bring slip‑on footwear for quick ship swaps, since luggage may be moved by crew between identical sister vessels overnight.
Finally, buy Cancel‑For‑Any‑Reason insurance that covers “inability to operate” clauses, not just weather delays. A modest premium today can save far more than the value of missed Cruise nights if drought forces an outright cancellation.

FAQ
- Are ships likely to be bused this week? Only if gauges fall another 20 cm; most operators still expect to sail the whole upper Danube.
- Will rain in Bavaria fix the problem? A single storm helps briefly, but a multi‑day pattern is needed to raise navigable depth meaningfully.
- Does Travel Insurance automatically cover low water? Regular policies rarely do; buy Cancel‑For‑Any‑Reason or a rider that names “provider unable to perform.”
