The following graphs are for inbound and outbound traffic at the ports of Los Angeles and Long Beach in TEUs (TEUs: 20-foot equivalent units or 20-foot-long cargo container).
To remove the strong seasonal component for inbound traffic, the first graph shows the rolling 12 month average.
On a rolling 12 month basis, inbound traffic was up 2.1% compared to the rolling 12 months ending in January. Outbound traffic was down 0.4% compared to the rolling 12 months ending in January.
The 2nd graph is the monthly data (with a strong seasonal pattern for imports).
Note: The Chinese New Year boosted inbound traffic in February, and will slow inbound traffic in March this year.
Trade has been strong - especially inbound - and setting record volumes most months recently.
In general imports have been increasing, and exports are mostly moving sideways recently.
