The tidal Garonne is well within its midsummer range, keeping Bordeaux round-trip itineraries on schedule. Hot, dry weather after August 6 could trim inflow and move risk from Normal toward Caution.
Current Conditions
Agen gauge: 1.72 m (normal range about 1.2 - 3.0 m), navigation risk = Normal.¹
Seven-Day Outlook
| Date | Forecast Stage | Trend | |
|---|---|---|---|
| Mon Jul 28 | 1.72 m | Stable | |
| Tue Jul 29 | 1.70 m | -2 cm | |
| Wed Jul 30 | 1.69 m | Stable | |
| Thu Jul 31 | 1.70 m | +1 cm | |
| Fri Aug 01 | 1.70 m | Stable | |
| Sat Aug 02 | 1.71 m | +1 cm | |
| Sun Aug 03 | 1.72 m | Stable | ² |
Three-Week Risk Forecast
| Period | Likelihood of Disruption | Confidence |
|---|---|---|
| Days 1-7 | Normal | High |
| Days 8-14 | Caution (persistent heat lowers inflow) | Medium |
| Days 15-21 | Caution (dry spell may linger) | Low |
A subtropical ridge is forecast to park over southwest France after August 6, boosting temperatures and cutting basin-wide rainfall. If runoff slips, slack-water windows at Bordeaux may shorten and sediment can collect near Cadillac, so operators will monitor stages closely. Keep Cancel-For-Any-Reason coverage in place; it refunds coach substitutions if depths fall below safe draft.³
Cruise-Line Responses
Spokesperson for Uniworld Boutique River Cruises notes that Brilliant Bordeaux sailings "adjust shore timings around tides when necessary and may reorder excursions if water levels demand."⁴
Spokesperson for CroisiEurope adds that the line's Garonne & Dordogne program "remains on schedule but can switch to coach transfers if sandbars restrict the approach to Libourne."⁵
Traveler Advice
Pack a brimmed hat, SPF 50, and a refillable water bottle, because the August sun reflects sharply off the broad tidal reach near Blaye.
Gangways at Cadillac and Bourg can sit steeply at low tide; wear shoes with firm tread and allow extra time for anyone with mobility concerns to traverse the ramp.
Review your cruise contract before final payment. Standard interruption clauses rarely cover tide-timing changes or low-water reroutes, whereas Cancel-For-Any-Reason riders typically reimburse up to 75 percent of prepaid, non-refundable costs if you decide to forgo extended coach segments.

FAQ
- How low is "too low" for Garonne cruise ships? Operators begin bussing segments when Agen drops below roughly 1.3 m, because shoals develop near the tidal limit.
- Can low inflow alter tidal timing? Yes, sustained drought upstream can shrink freshwater push and shave several centimeters off predicted highs.
- Does travel insurance cover tide-related delays? Only Cancel-For-Any-Reason or dedicated river-cruise riders reliably refund added hotel nights or missed segments.
