Monthly High Tide Flooding Outlook – March 2025
March 14 – Full Moon
March 29 – New Moon
Mariners and other coastal enthusiasts should expect higher tides on and around the dates of the full moon and new moon (known as spring tides). Low lying areas may flood, however high tides alone will likely not cause a significant impact on the coast in most areas unless accompanied by a storm or strong winds. Lower than normal low tides will also occur. In the Mid-Atlantic & Southeast, minor tidal flooding along the coast will occur, particularly in low lying areas. If a storm occurs at this time, increased levels of tidal flooding and coastal erosion may occur. Lower than normal low tides will also occur. In many locations of the Gulf Coast, the tidal range is relatively small compared to other regions of the U.S. so they will not be as significantly impacted by a perigean spring tide.
See the details on all the harbors and locations where NOAA is predicting possible and likely coastal flooding this month: The Northeast, Mid-Atlantic, Southeast, Gulf Coast, West Coast, and Hawaii.
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
