Amazon River Low Water Levels: Increased Navigational Risk During the 2026 Dry Season

During the 2026 dry season, the Amazon River is expected to experience low water levels, leading to increased navigational risks according to Gard's analysis. Seasonal fluctuations are normal, but forecasts suggest potential El Niño conditions may cause water levels to drop below usual averages. This could narrow under keel clearance margins and expose hazards that were previously underwater.

The river's channels may also change due to silting and sediment movement, making it crucial to rely on current navigational information and local pilot advice.

Gard notes that the Amazon region has historically been prone to grounding incidents, with claims data from 2021-2025 showing an approximate 35% increase in exposed cases compared to the previous three-year period. To mitigate these risks, shipowners and operators are advised to routinely check local draft limits, bathymetric updates, and regulatory notices.

It is essential to follow the latest under-keel clearance parameters issued by the local Captaincy of the Ports and ensure shipboard systems are fully operational to comply with local labor requirements during the dry season.

Given the heightened vulnerability to armed robbery, particularly during the dry season, ships and barge convoys carrying fuel products should exercise extreme caution. Crews must remain vigilant for nearby convoys and small craft, many of which may be difficult to detect. Due to the severe draft constraints, all relevant charter parties, contracts of carriage, and logistics service agreements must be thoroughly reviewed, with special attention given to clauses related to partial loading, transshipment, deviation, waiting time, demurrage, force majeure, and the allocation of additional operational costs.
