431,884 people crossed into the United States by car at Blaine in September 2026, up 12.3% from a year earlier. In the record back to 1996, the busiest September was 1996, with 978,290; the September average across 31 years is 573,210.
Blaine is the Peace Arch and Pacific Highway crossings together, the I-5 route between Vancouver and Seattle. The count is one-way and does not record nationality: it is everyone entering the U.S., so a Washington resident driving home from Vancouver counts the same as a Canadian visitor, and no one counts the trips north. Most southbound traffic at Blaine is Canadian, which is why the line carries the fall in British Columbia travel south since early 2025 — but it measures crossings, not who made them.
The hole in 2020 and 2021 is the border closure to non-essential travel, from March 2020 to November 2021. The second chart is freight: 28,372 trucks entered at Blaine in September 2026, up 7.1% on a year earlier.
