Port of San Diego

Maritime Risk Context

In the last 180 days, ArcNautical recorded 48 vessel arrivals at San Diego, with Tanker accounting for 20% of port calls — higher than the East Pacific regional average of 14%. San Diego in USA sits along the western coast of the Americas, where commercial shipping operates against a backdrop of seismic, volcanic, and ENSO-driven weather hazards. The Pacific Ring of Fire generates significant seismic and volcanic activity along the entire coast; Chile and Peru experience major earthquakes with sufficient frequency that seismic risk is material for both port infrastructure and voyage planning. The Panama Canal — the key chokepoint connecting the eastern Pacific with the Caribbean and Atlantic — has faced drought-related transit restrictions that limit vessel draft and daily transit capacity, forcing some operators to route via the Strait of Magellan or Cape Horn. El Niño/La Niña cycles produce sustained shifts in storm tracks and sea states.
