shipfinder.com seems to be a handy tool for checking what is actually happening at the strait.

The time is currently in the early hours of June 16 in Iran, so the transits reported for June 15 seems to be a final total. And that number is 17. Nine inbound, eight outbound.

Nice graph of transits over time too. The "biggest day" since June 1 is 18 transits.
