Upcoming king tides

King tides are the highest predicted tides of the year. They happen when a new or full moon lines up with the moon’s closest approach (perigee), and in many places they are biggest in winter or early summer.

The list below comes from NOAA tide predictions for 399 stations, ranked by how far each high tide rises above that station’s mean higher high water (MHHW). It is regenerated with every data refresh (last: 2026-10-17).

Why king tides matter for fishing and boating

Very high tides flood marsh edges and push bait into grass and flats that are dry most of the month, which is why many inshore anglers watch for them. They also mean faster currents in inlets on the falling tide, shallower clearance under bridges and, in low-lying towns, flooded ramps and parking lots.

The heights here are astronomical predictions only. A strong onshore wind, low air pressure or heavy river flow can add a foot or more; offshore wind can do the opposite. For flood warnings rely on the National Weather Service.

How we pick them

For each station we take NOAA’s high/low predictions for the next 365 days, keep the highest high tide of each day, and list the eight highest days that are at least three days apart (so one spring-tide series doesn’t fill the list).
