Border apprehensions rose from 6,076 in January to 8,870 in August, after peaking at 10,011 in May

U.S. Customs and Border Protection recorded 8,870 apprehensions on the Southwest Border in August 2026, up from 6,076 in January, according to the agency's Nationwide Encounters page. The monthly count climbed to 10,011 in May and has fallen each month since.

The monthly numbers

September was not yet reported when we checked on Oct. 22. These are the fiscal 2026 figures as CBP showed them; final statistics come only after the fiscal year is closed out.

The size of the swings

Our arithmetic from CBP's monthly figures: August is 2,794 higher than January, a rise of 46.0%. May to August is a drop of 1,141, or 11.4%. The month-to-month step from July to August was 426 fewer, or 4.6%. The eight months together add up to 67,943 recorded apprehensions, an average of about 8,493 a month. Those are totals of events, and the monthly values may be revised, so treat the percentages as descriptions of the current table rather than settled history.

What the figures are

CBP defines an apprehension as a case in which the U.S. Border Patrol physically detains or temporarily holds a person between ports of entry who is not lawfully in the country. The count is of enforcement events. One person can be counted more than once, and the series is not a census of everyone who crossed, everyone who tried, or unique migrants. Southwest Border is also not the same as CBP's "nationwide" encounters, which add other locations and categories.

CBP says the data come from live systems and can change because of corrections, definition changes, added information or encounters pending review, and that it has adjusted filters to keep law-enforcement-sensitive statistics out of public releases.

What the data cannot say

The pattern does not explain itself. Enforcement staffing, policy, seasonal conditions, routes, repeat encounters and attempts that avoid detection can all change what CBP records, and the monthly series alone cannot separate them. It does not show that border policy has worked or failed. To judge that, the numbers need to be set beside removals and returns, custody data, immigration-court backlogs and costs. We have not contacted CBP or DHS for this brief.
