Upper Danube levels are seasonally steady, with the key German gauge at Pfelling reading about 11.4 ft (3.48 m) this morning. Austrian gauges, including Kienstock in the Wachau, are likewise within routine late-summer ranges for navigation, and major cruise lines list no active advisories. Showers are spotty across Bavaria and Austria this week, so we keep the 7-day call at Normal and advise guests sailing in the next two to three weeks to reconfirm docking times and review Cancel For Any Reason timing with their advisor.^{1,5,9,10,11,12}

Current Conditions

Primary gauge: Pfelling (Pegel Pfelling). Latest reading 11.4 ft (3.48 m), normal range data unavailable. Risk level Normal for the Upper Danube, supported by steady readings at Pfelling and routine Austrian stages used by cruise vessels.^1,5,13

Seven-Day Outlook

Forecasts for Passau and Vienna point to light, on-and-off showers, roughly 0.20 to 0.50 in (5 to 12 mm) total, with only minor day-to-day stage changes expected on the Upper Danube. Austrian fairway listings show typical values at Kienstock near 7.5 ft (2.28 m), consistent with Normal operations. Seven-day navigation risk call: Normal.^3,4,5

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

ECMWF sub-seasonal guidance leans near normal on weekly precipitation across the Upper and Middle Danube through midperiod, with wider spread late that could allow a few stronger frontal passages. Treat week-three signals cautiously, and verify CFAR purchase windows and coverage caps before your final payment date.^7,8

Traveler Advice

If you are booked to sail this week, expect routine calls through Passau, Linz, the Wachau, and Vienna. Arrive a little early for city-center quays, keep cruise apps and emails enabled for day-of timing, 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. Flex independent time with refundable rail tickets, and review Cancel For Any Reason options 14 to 21 days before departure so you keep the broadest choices if patterns shift.
