The ships are back. Not in the way they were in 2021, when a hundred massive vessels sat idling off the coast of San Pedro like a floating parking lot, but they’re back. If you look at the horizon from Cabrillo Beach today, you see a steady, rhythmic pulse of steel. Los Angeles port traffic has become the definitive pulse check for the American economy. When it’s congested, your shoes cost more and your couch takes six months to arrive. When it’s fluid, we barely think about it.
But things are weird right now.
We aren't in a crisis, yet the numbers are creeping up toward record highs. The Port of Los Angeles handled nearly a million twenty-foot equivalent units (TEUs) in some months recently, specifically hitting a massive 939,600 TEUs in August 2024. That’s a 16% jump over the previous year. It’s a staggering amount of cargo. Gene Seroka, the Executive Director of the Port of Los Angeles, has been vocal about the fact that the "Global Supply Chain" is essentially a game of musical chairs where the music never stops, it just changes tempo.
The Stealth Boom in Los Angeles Port Traffic
Why is everyone shipping so much stuff right now? Honestly, it’s a mix of genuine demand and "just in case" anxiety.

Retailers learned a hard lesson during the pandemic. They realized that "Just-in-Time" inventory is a fantasy that dies the moment a single crane operator gets the flu or a canal gets blocked. So, we’re seeing a shift to "Just-in-Case." Companies like Walmart, Target, and Home Depot are front-loading their shipments. They aren't waiting for the holidays; they are bringing in the Christmas tinsel in July.
There's also the Red Sea factor. Because Houthi rebel attacks have made the Suez Canal a no-go zone for many carriers, ships are taking the long way around Africa. This adds weeks to voyages. When those ships finally hit the water, many shippers decide it’s safer to just send everything to the U.S. West Coast and rail it across the country rather than risk the uncertainty of East Coast or Gulf ports.
Then you’ve got the labor drama. Even though the International Longshore and Warehouse Union (ILWU) settled their contract, the mere memory of a strike makes logistics managers sweat. It's why Los Angeles port traffic spikes whenever there is even a whisper of trouble at other ports.
Why the "Ghost of 2021" Still Haunts San Pedro
Remember the "Great Supply Chain Disruption"? It wasn't just about too many ships. It was a failure of the "landside" operations. You had ships waiting to dock, but the docks were full of containers. The containers were full because there were no chassis (the trailers trucks use). There were no chassis because they were stuck under empty containers in suburban parking lots.
It was a total system collapse.
Today, the Port of Los Angeles is trying to be smarter. They’ve leaned heavily into the Port Optimizer, a data tool created with Wabtec. It’s basically a crystal ball for cargo. It lets terminal operators see what’s coming 40 days out. It sounds simple, but in the shipping world, knowing what’s in a box before it arrives is revolutionary.
But here is the catch.
Infrastructure is slow. The Port of Los Angeles and its neighbor, the Port of Long Beach, are constrained by the geography of Southern California. You can't just "build more port" when you're surrounded by millions of people and some of the busiest freeways on earth. Every time traffic increases, the pressure on the 710 freeway becomes a political and environmental flashpoint.
The Automation Argument: Robots vs. People
Walk onto a modern terminal like TraPac in Los Angeles and it feels like a sci-fi movie. Automated stacking cranes whir back and forth without a human in sight. These robots don't get tired. They don't take lunch breaks. They move containers with terrifying precision.
But automation is a dirty word in many circles.
The ILWU has fought hard to keep human beings in those cabs. Their argument is simple: automation doesn't necessarily move more cargo; it just moves it with fewer people. They point to the fact that during the 2021 peak, manual terminals often performed just as well, if not better, than the automated ones because humans can adapt to chaos in ways an algorithm can’t.
Still, the trend is clear. To handle the projected growth of Los Angeles port traffic over the next decade, the port has to get denser, not bigger. That means stacking containers higher and moving them faster.
The Zero-Emission Clock is Ticking
You can't talk about port traffic without talking about the air. San Pedro and Wilmington have some of the highest asthma rates in the region. It’s the "Diesel Death Zone."
The Clean Air Action Plan (CAAP) is the port's roadmap to zero emissions. By 2030, they want all cargo-handling equipment to be zero-emission. By 2035, they want every drayage truck—the short-haul rigs that move containers to local warehouses—to be zero-emission too.
This is a massive hurdle.
Electric trucks are expensive. A new Tesla Semi or a Nikola rig can cost three times what a diesel truck costs. Plus, the charging infrastructure is barely there. Imagine trying to charge 20,000 trucks a day when the California power grid is already struggling during a heatwave. It's a logistical nightmare that keeps port officials up at night.
If the port forces these changes too fast, small trucking companies will go bust. If they go bust, the containers sit on the dock. If the containers sit, Los Angeles port traffic grinds to a halt. It is a delicate, high-stakes balancing act.
Rail is the Secret Sauce
Most people think of trucks when they think of the port. But the real heavy lifting happens on the tracks. The Alameda Corridor is a 20-mile "rail expressway" that connects the ports to the transcontinental rail yards near downtown L.A.
About 60% of the cargo coming through the port is destined for places outside of Southern California. If the rail lines get backed up—which happened in 2022 when Union Pacific and BNSF struggled with staffing—the whole country feels it. Currently, the port is investing heavily in "on-dock" rail. The goal is to put the container directly from the ship onto a train, bypassing the truck trip entirely. It’s cleaner, faster, and way more efficient.
What This Means for Your Wallet
Basically, if you’re a business owner, you need to watch the "dwell time" stats. That’s the number of days a container sits on the dock. Right now, it’s hovering around 2.5 to 3 days for trucks. That’s healthy. If that number hits 5, start worrying. If it hits 9, start raising your prices.
We are also seeing a shift in where ships go. For a while, everyone fled to Savannah or New York to avoid L.A.’s drama. But the West Coast is winning back market share. Why? Because it’s still the fastest route from Asia to the U.S. heartland. A ship from Shanghai hits L.A. in about 14-18 days. To get to the East Coast, you’re looking at 30+ days.
Time is money.
Practical Steps for Navigating Port Volatility
If you are involved in shipping, or just someone wondering why your Amazon package is delayed, here is how you should read the situation:
1. Watch the Lunar New Year
Everything in Los Angeles port traffic revolves around factory cycles in China. When China shuts down for the New Year, the port gets a breather. That is your window to move goods without peak surcharges.
2. Diversify the Gateways
Smart companies don't put all their eggs in the San Pedro Bay basket anymore. While L.A. is the king, having a backup through Port Houston or even Prince Rupert in Canada is the only way to sleep at night.
3. Monitor the "Chassis" Availability
The secret killer of port efficiency isn't the ship; it's the trailer. Keep an eye on the pool of chassis. If the "Chassis Bill of Rights" or similar labor/regulatory shifts happen, it can change the flow of traffic overnight.
4. Go Green or Get Taxed
The Clean Truck Fund rate is already a reality. Shippers are paying $10 per TEU to fund the transition to zero-emission trucks. Expect these "green fees" to go up. Build them into your margins now so you aren't surprised later.
The Port of Los Angeles isn't just a place where ships park. It's a 7,500-acre engine that supports 1 in 9 jobs in the region. It’s messy, it’s loud, and it’s constantly on the edge of a nervous breakdown, but it's the reason our modern lifestyle exists. Stay updated on the monthly TEU counts and the rail departure times. Those numbers tell you more about the future of the economy than any stock market ticker ever will.
