just some general notes on the tides.
with a new moon on november 20, you would have roughly 2 highs and 2 lows on that day. its important to note too that tides are predictions, and can and do vary, mainly due to the wind and location.
for example a westerly wind like you had on november 20 will influence those highs and lows. as the water is flowing in to the bays and creeks, it will be pushing against the wind, so it won't come in at a precise rate. In my experience a west wind will keep that high tide out longer and water will come rushing in faster nearer to the predicted time of high tide. It will also push the tide out a bit further and sooner, once the high tide turns and starts to head back out again.
Location will influence tidal flow based on the geography that the tide is flowing around, over and through. If you have a narrow channel like and inlet or creek, the water can only flow through over time in a specific volume. Thus it is possible back bays and creeks, to still have water flowing in to some of the narrower way in the back areas, even after high tide has come and should be heading back down to low tide. Sort of like how when you pour water through a funnel, there will be a back log of water that cannot pass through neck as fast as the water enters the funnel.
