King Tide Calendars

King tides are the predicted highest high-tide and lowest low-tide events of the year and occur during a perigean (when the Moon is closest to Earth) spring tide (full and new moon).

2026 King Tides Calendar

NC King Tides’ definition of a “King Tide”: 

Some of the highest predictable water levels of the year, occurring during the perigean spring tides – that is, when the moon is either new or full and closest to Earth – and exceeding a local risk-based threshold of 4 ft MLLW (for NOAA Beaufort Duke Marine Lab NC Gauge #8656483).

The NC King Tides calendar does not predict coastal flooding. The occurrence of coastal flooding can be influenced by non-tidal factors, including meteorological forcing (e.g., wind and pressure), seasonal changes in sea level, and land-based factors (e.g., high groundwater, rainfall, infrastructure). We direct the reader to the NOAA Monthly High Tide Outlook for predictions of coastal flooding.
