Port of Durban

Maritime Risk Context

In the last 180 days, ArcNautical recorded 83 vessel arrivals at Durban, with Cargo accounting for 71% of port calls — in line with the Indian Ocean regional average of 68%. Routes serving Durban in South Africa cross a basin where the risk profile varies dramatically by sub-region. The western Indian Ocean — particularly waters off Somalia, the Gulf of Aden, and the Mozambique Channel — has been historically affected by piracy; while the 2011–2012 peak has subsided, the underlying drivers persist and periodic attacks are still reported. Monsoon timing (southwest June–September, northeast December–March) influences both piracy seasonality and commercial routing. Cyclone activity in the Bay of Bengal (April–May, October–December) and Arabian Sea (May–June, October–November) can produce sustained 100-knot winds. ArcNautical's stochastic scoring uses Monte Carlo to capture this seasonal uncertainty.
