These are astronomical predictions. An onshore wind, heavy rain or a storm can push water a foot or more higher, and that is when king tides flood low roads, docks and marsh-front yards. Check the forecast the week before.
Lowest tides
The same spring tides drain the water lowest. Good days for shelling, walking sandbars and exploring the flats; mind the time and the incoming tide.

What is a king tide?
“King tide” is the everyday name for the highest tides of the year. They come with the new or full moon (spring tides) when the moon is also at its closest to Earth, and they are strongest in the months when the sun lines up too. They are entirely predictable, which is why the dates above are known a year ahead.
