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 down 0.1% compared to the rolling 12 months ending in June. Outbound traffic was also down 0.1% compared to 12 months ending in June.
Inbound traffic has been increasing, and outbound traffic has been moving up a little recently after moving sideways.
The 2nd graph is the monthly data (with a strong seasonal pattern for imports).
Imports were down slightly year-over-year in July, exports were also down slightly year-over-year.
Overall traffic was a little soft in July probably due to the short strike. It is possible traffic will be close to the pre-recession peaks over the next few months.
