The Rhine's mid-reach is operating normally, with the key Kaub gauge around 7.4 ft (2.27 m), well above low-water thresholds used for navigation planning. No systemic constraints are in effect for the Middle Rhine between Bingen, St. Goar, and Koblenz. Expect routine cruising conditions this week. ¹²

A showery pattern early in the week should deliver roughly 1.2 in (30 mm) of rain around Koblenz, then taper to lighter amounts, supporting a generally steady hydrograph. Seven-day disruption risk is assessed as Normal. ³⁴

If you are sailing within the next two to three weeks, coordinate with your advisor to reconfirm docking times, watch the Kaub gauge day by day, and review Cancel For Any Reason purchase windows. For departures beyond mid-September, extended guidance favors near-normal precipitation, with only low-confidence late-period swings. ⁵⁶

Current Conditions

Primary gauge: Kaub (Pegel Kaub). Latest reading 7.4 ft (2.27 m). Key thresholds at Kaub are the low-water reference GlW 2.5 ft (0.77 m) and Mark I high-water 15.1 ft (4.60 m). Risk level Normal for the Middle Rhine cruise corridor. ¹²⁷

Seven-Day Outlook

Forecast tables show only minor day-to-day swings at Kaub, consistent with a stable river stage. Around 1.2 in (30 mm) of total precipitation is projected for the Koblenz area Monday through Sunday, which should modestly support levels without creating high-water issues. Seven-day navigation risk call: Normal. ³⁴

Three-Week Risk Forecast

Period	Likelihood of Disruption	Confidence
Days 1 to 7	Normal	High
Days 8 to 14	Normal	Medium
Days 15 to 21	Caution	Low

Extended-range ensemble guidance trends near normal on weekly precipitation for the Rhine basin through midperiod, with a wider spread late that allows for a few stronger frontal passages. Treat week-three signals cautiously and confirm CFAR purchase windows and coverage caps before final payment dates. ⁵⁶

Cruise-Line Responses

Spokesperson for Viking reports no active notifications on the "Current Sailings" page affecting Rhine itineraries. ⁸ Representative for Uniworld confirms "No New Travel Alerts at This Time" for Rhine programs. ⁹ A contact for Avalon Waterways notes no travel updates or alerts currently posted. ¹⁰ Scenic's travel-alerts page also lists no current advisories. ¹¹

Traveler Advice

Booked guests this week can expect routine operations through Bingen, St. Goar, Koblenz, and Cologne. Arrive a little early for pier transfers, keep cruise apps and email notifications enabled, and pack a light rain jacket for brief showers.

If you are shopping near-term dates, conditions support Normal operations. Ask your advisor to reconfirm docking locations 48 hours before embarkation, and verify that your policy covers supplier-initiated changes with interruption limits sized for last-minute hotels or rail.

For trips three or more weeks out, continue to monitor weekly updates as autumn fronts return. A flexible plan with refundable train tickets for independent time, plus a timely CFAR review, creates helpful buffers if patterns shift.

Methodology

We combine real-time WSV Pegelonline gauge data, ELWIS forecast tables and station thresholds, and ECMWF sub-seasonal anomaly guidance, applying Adept Traveler thresholds and a 1 m = 3.28084 ft conversion. ¹²³⁵¹²
