Port Congestion Eases on the West Coast, but Not Evenly

Quick answer: West Coast port congestion has eased meaningfully this quarter compared to the same period last year, though the improvement is uneven across individual terminals rather than uniform across the coast.
Port dwell times have been a persistent planning headache for years, and this quarter's data shows real, if uneven, improvement worth factoring into near-term routing decisions.
What the Data Shows
Average vessel dwell times at major West Coast terminals have improved meaningfully compared to the same period last year, continuing a gradual recovery from the worst congestion years, according to data tracked alongside federal freight statistics.
The improvement is not uniform — some terminals have returned close to pre-congestion norms while others still run meaningfully above baseline, making terminal-specific research worthwhile rather than assuming coastwide averages apply to your specific routing.
What Still Bottlenecks Behind the Terminal
Improved vessel dwell time at the dock does not automatically mean improved total transit time if inland rail connectivity out of that specific port remains constrained — the bottleneck has shifted for some terminals from the dock itself to the rail yard just behind it.
Shippers routing through a specific terminal should check both dock-side congestion data and inland connectivity separately before assuming an overall port congestion improvement applies fully to their specific routing.
What This Means Day to Day
For most teams working on West Coast port congestion, the theory matters less than what changes on Monday morning — recent government data on this front only tells part of the story. Laneage hears from readers in supply chain roles who are less interested in the abstract policy or strategy debate and more interested in what specifically to check in their own operation this week — a contract line, a packing checklist, a supplier conversation.
Walt Simmons's own reporting on this beat, cross-checked against industry reporting from outlets that track it closely, keeps coming back to the same pattern: the shippers and planners who do best are the ones who treat West Coast port congestion as a recurring line item to monitor, not a one-time decision made once and never revisited. That single habit — building a short recurring review into an existing planning cycle rather than creating a new standalone process — tends to matter more than any individual tactic covered above.
It also helps to name an owner. A lot of the mistakes Laneage sees on this beat do not come from a lack of information — the guidance above is not obscure — they come from nobody on the team being explicitly responsible for checking it on a regular cadence. If West Coast port congestion touches more than one department, put one name on it, even if the actual work stays distributed, so a slipping metric or an expiring exception has somewhere to land before it becomes a bigger problem. Our wider coverage of this beat has more on how other teams have split that ownership.
Where to Start This Week
Working through everything above in one sitting is not realistic for most teams, so it helps to prioritize. Here is a rough order of operations based on what Laneage typically sees pay off fastest:
- First: Average vessel dwell time has improved compared to the same period last year — this is usually a manageable first step even for a team without a lot of spare bandwidth, and it tends to surface pretty quickly whether the rest of the process needs a bigger rework or just a tune-up.
- Next: The improvement varies significantly by individual terminal, not uniformly coastwide — this is usually a manageable first step even for a team without a lot of spare bandwidth, and it tends to surface pretty quickly whether the rest of the process needs a bigger rework or just a tune-up.
- Finally: Inland rail connectivity out of the port remains a separate bottleneck at some terminals — this is usually a manageable first step even for a team without a lot of spare bandwidth, and it tends to surface pretty quickly whether the rest of the process needs a bigger rework or just a tune-up.
None of these steps require a large budget or a new system to start — most of the value comes from someone actually sitting down with the current process, the current supplier or carrier agreement, or the current data, and checking it against what is outlined above rather than assuming it already matches. Teams that skip straight to a technology purchase before doing this basic review tend to automate an already-broken process rather than fix it.
It is also worth revisiting this list on a set schedule rather than treating it as a one-time cleanup — our broader operational playbook covers how to build that review into a planning calendar. Conditions on West Coast port congestion shift — new suppliers, new regulation, new competitive pressure — and a checklist that was accurate a year ago is not a guarantee it still is today. See also our related coverage for how this connects to the rest of the beat.
Bottom Line
The coastwide trend is genuinely positive, but the terminal-by-terminal variation means shippers should check their specific routing rather than assuming a uniform improvement across every West Coast port.

Frequently Asked Questions
Has port congestion fully returned to pre-pandemic levels?
Most major terminals have improved significantly, though some individual terminals still run above pre-congestion baseline dwell times.
Is the vessel dwell time improvement enough to fix total transit time?
Not always — inland rail connectivity constraints behind some terminals can offset dock-side improvements, so total transit time should be checked separately.
Where can shippers get more detail on West Coast port congestion?
Laneage's coverage tracks this topic on an ongoing basis.
Laneage covers the operational and policy side of moving goods — from the dock to the border, and from the warehouse floor to the fulfillment center. Walt Simmons reports for Laneage on this beat, drawing on conversations with shippers, carriers, and compliance teams working through these exact questions every week.
