The Northwest Seaport Alliance (Seattle + Tacoma) Weekly Volumes & Metrics Report 5/27/25
Overview
For the week ending in 5/16 volumes were down for the second week in a row. They were almost static compared to the week before, both international imports and truck transactions saw a tiny dip (1-2%). Vessel lifts were up from the week prior, due in large part to empty containers being loaded to go back to international markets, but still down compared to the May 2024 average and the Q1 2025 average.
You can find last week’s report here. You can find the full vessel schedule, including the 4 week look ahead and breakdown by harbor, here.
