We find it to be a little busier than May but still not too crazy. Some of the more popular anchorages will fill up a little early and you will see more boats from PR. We tend to make advance reservations for any docks that we may be using since we have seen places like Bitter end fill up pretty early. For the mooring balls I would give yourself a little extra time since things seem to fill up a little earlier. Weather wise it is probably our favorite time to go down and we will be down again this year.
