This satellite video shows how cargo-ship backlogs in Southern California ports surged from 0 to 100 in 2 years
- Satellite data from Spire Maritime shows how the shipping backlog in California has progressed.
- Backlogs at ports in Los Angeles and Long Beach have broken multiple records this year.
Look no further than satellite data to see how congestion at ports in Southern California surged in the past two years.
Before the pandemic, the ports in Long Beach and Los Angeles typically averaged zero to one ships at anchor, waiting to dock and unload. The highest backlog that the ports, which are responsible for nearly half of all US imports, had seen was 17 ships, according to the executive director of the Marine Exchange of Southern California.

In the satellite data from November 2019, it appears to show only two cargo ships that have not yet docked at the ports. The ports typically encounter more demand in the three months leading up to the holiday shopping season.
At the onset of the pandemic, COVID-19 shutdowns slowed port traffic, as well as the locations' capacity for unloading and reloading vessels. But, by the latter half of 2020, panic-buying and surging demand for tech as well as household products buoyed maritime traffic at the same time as the holiday-shopping season.
In a satellite depiction from the same month a year later, it shows what appears to be over 10 vessels waiting outside the ports.
Backlogs truly began to pick up in 2021. The ports in Los Angeles and Long Beach hit multiple fresh records this year, as consumer demand continued to skyrocket, while the ports were still working to recover from COVID-19 setbacks.
In February, the ports hit a record 38 ships waiting to dock. The red dot groupings appear to show the ships waiting in designated holding patterns that provide clear shipping lanes for incoming and outgoing traffic.
Seven months later, that number nearly doubled - a sign the
Experts predict the shipping crisis will only get worse in the coming months, as retailers prepare for the peak holiday shopping season.
The backlog is not expected to clear until 2023, according to industry officials.
