Monthly High Tide Flooding Outlook – March 2026
Note that while NOAA only makes these flooding predictions for harbors with National Ocean Service water level stations, other locations along the coast may experience similar high-water events during these time periods.
March 3 – Full Moon
March 18 – New Moon
View the detailed flooding report for harbors in every region below, and make sure to print your tide charts from US Harbors to be prepared for the high water level days in your favorite harbor.

About these Predictions: “These flooding likelihoods are derived from a probabilistic model that incorporates tide predictions, sea level rise trends, and seasonal changes in coastal sea level to predict the potential that a higher than normal high tide may exceed established National Ocean Service flood thresholds. During these periods, high tide flooding may occur in flood-prone areas.” NOAA
