Monthly Ship Traffic Statistics
Strait of Hormuz crossings detected by live AIS monitoring · hormuz.data-tracking.net
Each month's page details detected vessel crossings between the Persian Gulf and the Gulf of Oman, the estimated seaborne oil outflow, vessel-type breakdowns and the largest tankers of the month. Detection is AIS-based, so wartime jamming makes these conservative lower bounds — see the methodology and FAQ.

Monitoring began 8 March 2026, twelve days into the Iran war; counts before
late July 2026 are additionally depressed by an upstream AIS coverage gap. The current month is
