The year's biggest tides

King tides near you

King tides are the highest tides of the year. They arrive with the new and full moon when the moon is closest to Earth, and in many places they top docks, flood low roads and fill the marsh to the tree line. Because they follow the moon and sun, every one is predictable a year ahead. Pick a town to see its next 12 months of king tides, with times and heights from NOAA.

How to plan around them

  • Predictions are astronomical. Onshore wind, rain or a passing storm can add a foot or more, so check the forecast that week.
  • The highest tide of the day is the one to watch. On most of the East Coast that alternates between morning and evening.
  • The same spring tides bring the year's lowest water: the best days for shelling and walking the flats.
