Why did August 2026 replace September as the peak shipping month?

According to Jonathan Gold of the NRF, the peak season started early and stretched across the summer and early fall, with August ultimately becoming the busiest month. This represented a departure from traditional patterns where September typically marks the annual peak. The extended nature of this year's season meant that month-to-month differences often amounted to minimal variations.

What are the forecasted container volumes for the remainder of 2026?

The Global Port Tracker projects September at 2.28 million TEUs (revised down from 2.31 million), October at 2.25 million TEUs, and November at 2 million TEUs. All of these months are expected to remain above their 2025 equivalents, with September and October showing year-over-year increases of 8.2% and 8.5% respectively.

What is driving import demand despite weakening economic conditions?

Ben Hackett, founder of Hackett Associates, attributes the strong import volumes to robust consumer spending that has persisted despite indicators of economic weakness, declining consumer confidence, and increasing inflation. Most holiday merchandise has already arrived at ports, with remaining shipments focused on last-minute replenishment and preparation for early 2027.

How does the 2026 full-year import forecast compare to 2025?

The NRF forecasts full-year imports across Global Port Tracker-covered ports at 25.8 million TEUs, representing a 1.4% increase from 2025. This modest growth reflects the extended but moderating peak season combined with expected volume declines through the final months of the year.

Should supply chain teams expect an abrupt volume drop in Q4?

No. The projections indicate a gradual retreat from summer highs rather than an abrupt decline in cargo demand. Despite expected month-to-month slowdowns, September and October volumes will remain elevated compared to year-earlier levels, suggesting a more measured transition than a cliff-like demand collapse.

The signal

The National Retail Federation reports that the extended U.S. peak shipping season is moderating after an unusually prolonged stretch of elevated container volumes spanning summer and early fall 2026. August emerged as the year's busiest month at 2.3 million TEUs, surpassing the traditionally anticipated September peak, with volumes now expected to decline gradually through year-end as retailers transition from holiday merchandise stocking to inventory replenishment and early 2027 preparations.

September forecasts were revised downward to 2.28 million TEUs (still up 8.2% year-over-year), followed by October volumes of 2.25 million TEUs, indicating a measured retreat from summer highs rather than an abrupt demand collapse. Despite weakening economic indicators and declining consumer confidence, sustained retail spending continues to support above-trend import levels, positioning full-year volumes at 25.8 million TEUs, representing 1.4% growth versus 2025.

Frequently Asked Questions

What This Means for Your Supply Chain

Simulation Suggestion

this month

What if holiday merchandise restocking accelerates earlier than expected?

Model the impact of retailers advancing their Q4 replenishment orders by 2-3 weeks, creating a second demand surge in October. Simulate effects on port congestion, container availability, and transportation costs across U.S. import gateways.

What if consumer spending weakens and Q4 volumes drop 5-8% below forecast?

Scenario: Economic headwinds intensify, driving consumer spending lower. Model the ripple effects of 5-8% volume decline against current September-October forecasts. Analyze port utilization, freight rate pressure, and inventory carrying costs for retailers.
