Executive Summary
The Moselle is steady at just above its long‑term low‑water mark, allowing normal navigation for Cruise vessels. Forecast heat and limited rainfall suggest a slow downward trend, so travelers should watch for minor restrictions later in July.
Current Conditions
The Trier Up navigation gauge shows 233 cm today (normal operating band 224 cm – 520 cm), indicating full draft for passenger ships and no immediate restrictions.1
Seven‑Day Outlook
Daytime highs will surge into the mid‑80s °F by mid‑week, with only one weak frontal shower on Thursday. No significant rain is projected, so levels should drift only 5–10 cm lower, remaining within the safe range.2
Three‑Week Risk Forecast
| Period | Likelihood of Disruption | Confidence |
|---|---|---|
| Days 1–7 | Normal | High |
| Days 8–14 | Caution | Medium |
| Days 15–21 | Caution | Low. |
Warm, mostly dry weather dominated by a persistent continental high will limit basin inflow, while ensemble hydrological models show an increasing probability of falling below the mean low‑water threshold after mid‑July.3 A Cancel‑For‑Any‑Reason policy remains the best hedge against last‑minute coach swaps.
Cruise‑Line Responses
Spokesperson for Viking Cruises reports that regular Moselle sailings resumed in April, yet ships remain staged in opposite directions so a rapid “ship‑swap” can bypass any renewed lock or water‑level interruption.4
Commercial team for AmaWaterways confirms all June departures are running as scheduled and reminds guests that itineraries, Hotel packages, and port calls remain subject to change if river conditions deteriorate.5
Traveler Advice
Plan shore excursions with flexibility because hot afternoons can prompt local authorities to impose reduced speed limits that shift daily docking times. Stay hydrated, wear light layers, and keep a hat handy during walking Tours.
If booking for late July or August, ask your advisor to place you on a vessel that carries shallow‑draft certification and maintains sister ships nearby, which minimizes disruption if water levels fall further.
Always buy a comprehensive travel‑insurance policy that covers “river‑impassable” scenarios, and verify that pre‑ and post‑cruise rail segments can be re‑ticketed without hefty change fees.

FAQ
- Is the Moselle closed anywhere right now? No, all locks reopened in March 2025 and traffic is moving normally.
- When do low‑water problems usually peak? Late August into early September, when evapotranspiration is highest and rainfall is often scarce.
- Will my Cruise be canceled if levels drop below 224 cm? Not immediately. Lines first lighten fuel and water loads, then pivot to ship‑swaps or short coach hops before canceling outright.
