Ongoing drought and repeated heatwaves have driven the Rhine to record lows at key gauges like Kaub and Cologne through early August 2026, with minimal Alpine snowmelt and scant rainfall limiting recovery prospects. Trader consensus spreads probabilities across September and October windows, reflecting uncertainty in seasonal rainfall forecasts and the timing of cooler, wetter autumn patterns that historically ease low-water restrictions on inland shipping. The sizable share assigned to no return by November underscores concerns over prolonged dry conditions extending into fall. Fresh precipitation events or sustained temperature drops in the coming weeks could shift sentiment toward earlier resolution, while continued dryness would reinforce later or unresolved outcomes.
