The first graph shows the rolling 12 month average of loaded 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). Although containers tell us nothing about value, container traffic does give us an idea of the volume of goods being exported and imported - and possible hints about the trade report for February. LA area ports handle about 40% of the nation's container port traffic.

To remove the strong seasonal component for inbound traffic, this graph shows the rolling 12 month average.

On a rolling 12 month basis, inbound traffic is up 17% and outbound up 9%.

The 2nd graph is the monthly data (with strong seasonal pattern).

For the month of February, loaded inbound traffic was up 7% compared to February 2010, and loaded outbound traffic was up less than 1% compared to February 2010 - and down compared to January 2011. This suggests the trade deficit with China (and other Asians countries) probably increased in February.
