Operations on the tidal Garonne through Bordeaux look normal this week. The Bordeaux gauge sits near 13.6 ft (4.16 m) with green flood vigilance, and the estuary system is macrotidal, so schedules flex to tides. 126 Seven-day guidance for Bordeaux shows only light showers, roughly a few tenths of an inch, which is not enough to drive sustained stage changes. 4 Travelers should confirm pier times that follow tide windows, coordinate with an advisor, and keep flexible insurance options in mind.

Current Conditions

Primary gauge: Bordeaux, La Garonne à Bordeaux [station O972001001]. 1 13.6 ft (4.16 m), typical tidal swing 6.6 to 16.4 ft [2 to 5 m]. Risk level Normal based on today's reading and green vigilance at the station. 326

Seven-Day Outlook

Chart unavailable. Data summary for the Bordeaux reach: model-guided daily forecasts total around 0.20 in (5 mm), concentrated midweek, with many dry hours otherwise. 4 Because movements are planned to SHOM tide windows along the Gironde-Garonne axis, only brief, routine timing adjustments are expected. The call is Normal for the next 7 days. 5

Tides remain the dominant driver, with late-summer Atlantic fronts bringing only intermittent showers. In this macrotidal system, navigation risk hinges more on tide timing and currents than on low river inflow, so disruptions are uncommon absent exceptional weather. If considering Cancel For Any Reason, review purchase windows and coverage limits now. 67

Traveler Advice

Booked guests over the next two weeks should plan on normal operations. Expect pier times to flex around favorable tide windows at Bordeaux, Blaye, or Pauillac, and watch your line's app or emails 48 to 72 hours before embarkation. 5

If you are shopping near-term dates, this is a favorable window. Look for itineraries that include Bordeaux overnights and daytime calls in the Médoc and Blaye, which pair well with tidal scheduling. Choose flexible fares, or insurance, that allow small timing changes without heavy penalties.

For trips more than three weeks out, keep monitoring but avoid changes based on today's outlook. The Garonne-Gironde system's macrotidal range and maintained channels generally provide wide operational margins outside unusual wind or storm setups. 6
