Tidal stages in the lower Rhine delta sit well within midsummer norms, so Amsterdam-to-Antwerp sailings remain on schedule. A hot, dry ridge after August 6 could slow Rhine inflow and nudge risk from Normal toward Caution.
Current Conditions
Dordrecht (Stroomkade) gauge: 1.12 m NAP (normal range ≈ 0.6 - 1.5 m), navigation risk = Normal.¹
Seven-Day Outlook

| Mon Jul 28 | 1.12 m | Stable | |
| Tue Jul 29 | 1.10 m | -2 cm | |
| Wed Jul 30 | 1.09 m | Stable | |
| Thu Jul 31 | 1.10 m | +1 cm | |

Three-Week Risk Forecast
| Period | Likelihood of Disruption | Confidence |
|---|---|---|
| Days 1-7 | Normal | High |
| Days 8-14 | Caution (persistent heat trims inflow) | Medium |
| Days 15-21 | Caution (ridge may linger, spot storms) | Low |
A subtropical high is forecast to park over western Europe after August 6, boosting evaporation while Rhine tributaries run low. If inflow slips, slack-water windows narrow at tidal locks like Krammersluizen, and silt can gather in approaches to Ghent and Bruges. Cancel-For-Any-Reason coverage will refund coach transfers if depth falls below safe draft.³
Cruise-Line Responses
Spokesperson for Viking River Cruises reports that Holland & Belgium departures are operating normally, while reminding guests that itineraries "may be adjusted or motor-coached if water levels or lock closures affect any segment."⁴
Spokesperson for AmaWaterways states that the line "monitors Rijkswaterstaat gauges twice daily and can pivot to low-water contingency coaches while protecting the core sightseeing program."⁵
Traveler Advice
Summer sun reflects sharply off the wide Dutch polders, so pack a brimmed hat, polarized sunglasses, and SPF 50. Afternoon highs near 86 °F can feel warmer on open decks where wind is light.
Floating pontoons at Hoorn and Veere ride with the tide, but low-water slack may leave gangways steeper than usual. Wear shoes with solid tread, and allow extra time for anyone with mobility concerns.
Review your cruise contract before final payment. Standard interruption clauses rarely compensate for 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 skip extended coach segments.
Methodology
Gauge data come from Rijkswaterstaat's live Waterinfo feeds, while hydrometeorological inputs blend KNMI seven-day forecasts with publicly available ECMWF ensemble guidance.⁶

FAQ
- When do Dutch itineraries start bussing segments? Lines begin coach transfers when Dordrecht drops below roughly 0.8 m NAP, because shoals form near the Haringvliet junction.
- Can low Rhine inflow affect tidal timing? Yes, sustained drought upstream can shave several centimeters off predicted highs and lengthen slack-water periods at locks.
- Which insurance best covers water-level issues? A Cancel-For-Any-Reason rider offers the broadest refund if you opt out once coaches replace sailing days.
