Rhône River Water Levels Outlook, Week of September 22, 2025

The Rhône basin is on green flood vigilance, and normal navigation is expected for cruise movements between Lyon, Avignon, and Arles, with routine lock operations. Passing showers are likely midweek, but modeled totals are modest, so only small day-to-day level changes are expected. Travelers should reconfirm pier details in Lyon or Avignon 24 hours before embarkation, watch updates 48 hours before sailing, and consider Cancel For Any Reason timing if they are inside final payment windows. 1,3,7,8
Current Conditions
Primary gauge: Pont de Beaucaire, near Tarascon and Avignon. Data unavailable. Risk level Normal, supported by green vigilance on the Grand Delta segments that include the lower Rhône cruise corridor, and calm status upstream in the Rhône amont-Saône territory. 1,3,4,6
Seven-Day Outlook
Guidance shows periodic light showers across Auvergne-Rhône-Alpes and Provence, with basin-average rainfall roughly 0.3 to 0.8 in (8 to 20 mm). No strong high-water signal appears for the cruise corridor, and any fluctuations should remain minor. Seven-day risk call: Normal. 2,5,7
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 | Normal | Low |
An early-autumn Atlantic pattern favors passing fronts without a prolonged heavy-rain signal over the Rhône headwaters. Treat weeks two and three as probabilistic, and, if CFAR coverage fits your needs, confirm purchase windows and per-trip caps before final payment. 5,8
Cruise-Line Responses
Data unavailable.
Traveler Advice
Booked guests should expect normal operations this week. Reconfirm Lyon or Avignon embarkation details the day before, allow extra time for city transfers during showers, and keep luggage manageable for short quay walks between coach drop-offs and gangways. 2
Near-term shoppers can prioritize itineraries that include both Viviers and Arles, since these ports are rarely affected at current levels. Ask your advisor about cabin deck heights, included transfers between Lyon Part-Dieu or Lyon-Saint-Exupéry and the quay, and flexible rail fares for pre- or post-nights. 6
Planning beyond three weeks, keep deposits flexible where possible. Set reminders to recheck this spoke two weeks, then three days before sailing, and review your insurance terms, especially CFAR waiting periods and reimbursement ceilings. 8
