Port congestion is not a single event. It is a collision of several overlapping pressures that compound each other throughout the summer and fall months. Understanding those root causes is the first step in building a drayage strategy that holds up when things get tight.
- Import surges are the most visible driver. Retailers restocking for back-to-school and holiday seasons flood major gateway ports with container volume, often arriving in concentrated windows that outpace terminal processing capacity. When vessel arrivals cluster together, yard density spikes and gates become bottlenecks.
- Equipment shortages make the problem worse. Chassis availability is one of the most underappreciated variables in port congestion planning. During high-volume periods, chassis pools deplete faster than they are returned. A drayage provider without reliable depot access or chassis pool relationships cannot move containers efficiently, regardless of how many drivers they have available.
- Driver capacity is the constraint that most shippers fail to account for early enough. Licensed dray drivers are a finite resource. The carriers and beneficial cargo owners with standing contracts and pre-allocated driver schedules are the ones who get covered first. Everyone else competes for what is left, at whatever rate the market demands.
When Peak Season Typically Starts
Most shippers think of peak season as a late-summer problem. In practice, the window opens earlier than that, and waiting until July to act means the planning window has already closed.
The Late Spring Ramp
Congestion at major U.S. ports typically begins building in May. Inbound container volumes start climbing as Asian manufacturers ship goods ahead of summer retail cycles. Drayage providers begin allocating their committed capacity to contracted customers during this period, which means available spot capacity shrinks before most shippers realize it is happening.
Summer Congestion Windows
June through August represent the core of summer port congestion. Terminal dwell times extend, gate queues lengthen, and free time on containers erodes faster than expected. Shippers who have not locked in drayage capacity by this point often find themselves paying premium rates for secondary carriers or watching their detention charges climb while they search for a driver.
Back-to-School and Holiday Freight
The congestion window does not end in August. Back-to-school merchandise and early holiday inventory push import volumes through September and into October. Shippers moving consumer goods, apparel, or seasonal products face a second wave of pressure just as the first begins to ease. Intermodal capacity planning must account for both phases, not just the initial summer surge.
What Happens When You Wait Too Long
The consequences of delayed peak season drayage planning are not just operational inconveniences. They carry real and measurable costs that erode margin and create downstream disruptions.
- Higher Spot Rates: When contracted capacity is full, available drivers command a significant rate premium. Spot drayage rates during peak periods can run 20 to 40 percent above contracted lane pricing, and in extreme congestion scenarios, capacity may simply not be available at any price.
- Missed Free Time and Demurrage Fees: Every container has a free time window at the terminal. When a driver cannot be dispatched quickly, that clock runs out. Demurrage fees at major ports currently range from $75 to $450 per container per day depending on the port and carrier, and they accrue quickly when the yard is congested and port delays occur.
- Detention Charges: The mirror problem to demurrage, detention charges apply when a chassis or container is held at a warehouse or distribution center beyond the allowed free time. Without precise driver scheduling and clear communication between dispatch and the receiving facility, detention charges stack up on both ends of the move.
- Increased Dwell and Storage Fees: Containers that cannot be picked up promptly may be moved to off-dock storage, triggering additional storage fees on top of demurrage. During peak periods, off-dock lots fill quickly, and availability is not guaranteed.
- Missed Delivery Commitments: For time-sensitive retail or manufacturing supply chains, a delayed container is not just an extra cost. It can mean a missed shelf-set, a halted production line, or a chargeback from a major retail customer.

Capacity Planning Best Practices for Peak Season Drayage
Proactive intermodal capacity planning is the only reliable defense against peak season disruption. Vague advice about “booking early” is not enough. Here is what that actually looks like in practice.
Securing Contracted Lanes Early
Reach out to your drayage provider no later than March or April to discuss volume commitments for the summer period. Contracted lane pricing and capacity guarantees are negotiated in advance, and providers extend those terms to customers who signal their needs early. Shippers who approach this conversation in June are already behind.
Driver Allocation and Pre-Booking
A drayage provider’s dispatch structure matters as much as their fleet size. Ask specifically how drivers are allocated to customers during surge periods. Are your lanes pre-assigned to specific drivers? Does the provider have a dedicated dispatch team, or does surge volume get absorbed into a shared pool? Pre-booked driver allocation ensures your freight is not deprioritized when demand spikes.
Terminal Coordination and Depot Access
Not all drayage providers have the same level of terminal relationships or depot access. During peak season, providers with established gate appointments, trusted carrier status at major terminals, and access to multiple chassis pool depots can move containers when others cannot. Ask your provider where they source chassis during high-demand periods and what their average turn time looks like at the terminals serving your cargo.
Holiday Scheduling and Staffing
Peak season drayage runs into a staffing reality that rarely gets discussed: driver availability drops around holidays. Labor Day, Columbus Day, and early Thanksgiving travel all create coverage gaps at key moments in the fall freight cycle. A provider without contingency staffing plans will slow down exactly when volumes demand speed. Confirm that your provider has holiday scheduling protocols in place before the season begins.
Backup Planning
Even well-prepared shippers encounter disruptions. Vessel delays, weather events, and sudden volume spikes can exceed any provider’s committed capacity. Identify a secondary drayage partner before peak season begins, and ensure your primary provider knows you have that coverage. Having a backup is not a lack of loyalty; it is responsible supply chain management.
Communication Protocols During Surge
Operational reliability during peak season drayage depends on communication that is structured, proactive, and consistent. When volumes spike, the shippers who get served best are the ones whose providers have clear visibility into their freight pipeline.
Share Your Cargo Schedule Early
Share your cargo arrival schedule with your drayage provider at least two weeks in advance. Provide vessel names, ETAs, container numbers, and consignee details as soon as they are confirmed. The earlier your provider can schedule dispatch, the better positioned they are to pull your container during the terminal’s optimal gate hours and avoid demurrage exposure.
Establish a Single Point of Contact
Establish a single point of contact on both sides of the relationship for surge communication. During congestion events, fragmented communication between multiple contacts causes delays. Know who calls whom, what information is required, and what the escalation path looks like if a container is at risk of exceeding free time.
Require Real-Time Visibility
Real-time status updates are not optional during peak season. Your provider should be able to tell you where your container is in the pickup process, what the current terminal dwell conditions look like, and whether any detention risk is developing at the delivery site. If that visibility is not part of your current relationship, that is a gap worth addressing before summer port congestion arrives.
Secure Your Peak Season Capacity With Liberty Container Express
