How the seasons move auto transport prices and availability, and how to time your shipment for the best rate.
Auto transport has seasons, and they are not the ones people expect
Car shipping is a capacity market. Prices move with how many carriers are running your route against how many people want space on them, and that balance swings by month in ways most guides get roughly backwards.
What follows is not an industry estimate. It is what happened across Neptune's own dispatch records, comparing the median price in each calendar month against the median for the whole set.
The national picture, month by month
| Month | Against the annual median |
|---|---|
| January | level |
| February | 11% below |
| March | 8% below |
| April | 6% below |
| May | 6% above |
| June | 6% above |
| July | 6% above |
| August | level |
| September | level |
| October | 11% below |
| November | 11% below |
| December | 6% below |
The summer peak is real: May through July runs about 6% above the annual median, driven by household moves, students and the general willingness to travel. Nothing surprising there.
The cheap months are the surprise. February, October and November all sit about 11% below the annual median, and they are the three best months to ship if your dates are genuinely flexible. Autumn in particular is often described as a peak season. Across our book it is not.
Why "ship in winter to save" is only half right
Winter gets recommended constantly, and it is partly true. December sits 6% below the median and February is among the least expensive months of the year. But January is not cheap at all: it sits level with the annual median, because it carries the heaviest southbound snowbird traffic of the year.
Winter also costs you predictability. Mountain passes on the northern routes and lake-effect weather across the Midwest reduce how many carriers will commit to a firm date between roughly December and February. The rate may be lower; the pickup window is usually wider.
The snowbird corridor runs on its own clock
If you are shipping between the Northeast or Midwest and Florida, ignore the national table. That corridor is almost perfectly inverted by direction, and the effect is far larger than the national swing.
| Month | Heading south to Florida | Heading north from Florida |
|---|---|---|
| January | 18% above | 20% below |
| April | 18% below | 33% above |
| May | 18% below | 60% above |
| June | 12% below | 40% above |
| August | 13% above | level |
| October | 6% above | 20% below |
| November | level | 20% below |
Two things fall out of this that are worth knowing before you book.
The southbound peak is January, not the autumn. Demand builds through the autumn, but the highest median we record heading south is January, when the season is fully loaded and everyone is trying to be settled before the winter.
The northbound return is the sharpest price movement on the whole book. May sits 60% above its own direction's median. April and June are not far behind. If you are bringing a car back north in late spring, you are buying into the tightest window Neptune sees all year, and booking three or four weeks ahead is worth considerably more than usual.
The mirror image is the opportunity. Heading south in April or May, or north in October or November, means travelling against the flow, and carriers who would otherwise run that leg empty price it accordingly.
What this means for your booking
- Flexible dates beat a clever month. A pickup window with two or three days of give in it does more for your price on most lanes than choosing the right month.
- If you can choose a month, choose February, October or November. Nationally those are the three lowest, and on the snowbird corridor October and November are cheap northbound too.
- Avoid booking against the seasonal flow at the last minute. Late spring northbound out of Florida, and January southbound into it, are the two windows where late booking costs the most.
- Weigh rate against certainty in deep winter. December and February price well, but weather widens pickup windows on the northern routes.
For what shipments actually cost in absolute terms rather than as a seasonal swing, see our car shipping cost guide, which publishes bands from the same dispatch records.
These figures describe Neptune's own completed shipments, not the industry. They cover cars and SUVs; pickups, vans and oversized loads move differently. They mix open and enclosed transport, because our dispatch records carry no transport-type field.
