Good thing we are talking normal monthly tidal variations (not seasonal) which vary by meters, not centimeters.

  Not in Suez though. Yes, the high tide is a better opportunity to do it, the tides over the next couple of weeks are still within 20-30 cm. The worst day in the next 30 days is 60 cm below the highest. But maybe the dredge only made a few centimeters of difference running for 5 days, who knows.
