NOAA High Tide Bulletin
          SPRING 2022: When you may experience higher than normal tides
            between March and May 2022.


The rising and falling of the sea is a phenomenon upon which we can always depend. Tides are the regular rise and fall of the sea surface caused by the gravitational pull of the moon and sun and their position relative to the earth. There are some factors that cause the tides to be higher than what is "normally" seen from day to day. This bulletin tells you when you may experience higher than normal high tides for the period of time between March and May of 2022. We also publish annual high tide flooding reports that present a broad outlook of what to expect for a given year in terms of high tide flooding, as well as a summary of high tide flooding events for the previous calendar year.  Higher than normal high tides alone do not necessarily cause coastal flooding. However, they are becoming increasingly impactful due to continued sea level rise. High tide flooding that inundates busy streets, and washes out beaches is more likely to occur during these periods depending on your location along the coast.  More severe flooding may result if adverse weather—heavy rains, strong wind or big waves—conditions are present.

 NORTHEAST OUTLOOK
 Dates: No dates in March
                          April 18-20
                          May 15-19 Locations: Tide stations at the following locations have the greatest chance of seeing high tide
                          flooding: Bar Harbor, ME; Portland, ME; Boston, MA; Kings Point, NY
                            Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? In May, a perigean spring tide will be occurring. This is when the moon is either new or full and closest to earth.  Higher than normal high tides and lower than normal low tides will occur.
                            Tides will increase leading up to and after the June 21 summer solstice, due to the position of the sun relative to the earth's equator.
                            Mean sea level is typically higher in the late spring due to changing weather patterns and increasing water temperatures. What kind of impact might I expect along the coast? 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.
 MID-ATLANTIC OUTLOOK
 Dates: No dates in March
            No dates in April

            flooding: The Battery, NY; Bergen Point, NY; Sandy Hook, NJ; Atlantic City, NJ; Washington, DC
              Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? In May, a perigean spring tide will be occurring. This is when the moon is either new or full and closest to earth.  Higher than normal high tides and lower than normal low tides will occur.
              Tides will increase leading up to and after the June 21 summer solstice, due to the position of the sun relative to the earth's equator.
              Mean sea level is typically higher in the late spring due to changing weather patterns and increasing water temperatures. What kind of impact might I expect along the coast? Minor tidal flooding along the coast, in particular 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.
 SOUTHEAST OUTLOOK
 Dates: No dates in March
            No dates in April
            May 15-18 Locations: Tide stations at the following locations have the greatest chance of seeing high tide
            flooding: Duck, NC; Charleston, SC; Fort Pulaski, GA
              Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? In May, a perigean spring tide will be occurring. This is when the moon is either new or full and closest to earth.  Higher than normal high tides and lower than normal low tides will occur.

            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.
 GULF COAST OUTLOOK
 Dates: No dates March - May 2022 Locations: Texas, Louisiana, Mississippi, Alabama, Western Florida coast.
            Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? The Gulf Coast will not be significantly impacted. Why won’t they be impacted? 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.
 WEST COAST OUTLOOK
 Dates: No dates in March - May 2022 Locations: Tide stations at the following locations have the greatest chance of seeing high tide
                flooding: California, Oregon, Washington State
                  Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? The West Coast is unlikely to experience coastal flooding based primarily on tides this spring. What kind of impact might I expect along the coast? The West Coast will not be significantly impacted.
 PACIFIC ISLANDS OUTLOOK
 Dates: No dates for March
            No dates in April
            May 16-19 Locations: Tide stations at the following locations have the greatest chance of seeing high tide
            flooding: Hawaii, Guam, American Samoa, Midway, Kwajalein, and Wake Island.
              Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? In May, a perigean spring tide will be occurring. This is when the moon is either new or full and closest to earth.  Higher than normal high tides and lower than normal low tides will occur.
              Tides will increase leading up to and after the June 21 summer solstice, due to the position of the sun relative to the earth's equator.
              Mean sea level is typically higher in the late spring due to changing weather patterns and increasing water temperatures. What kind of impact might I expect along the coast? Minor tidal flooding along the coast, in particular 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.
 ALASKA OUTLOOK
 Dates: No dates for March
            No dates in April
            May 16-18 Locations: Tide stations at the following locations have the greatest chance of seeing high tide
            flooding: Alaska
              Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? In May, a perigean spring tide will be occurring. This is when the moon is either new or full and closest to earth.  Higher than normal high tides and lower than normal low tides will occur.
              Tides will increase leading up to and after the June 21 summer solstice, due to the position of the sun relative to the earth's equator.
              Mean sea level is typically higher in the late spring due to changing weather patterns and increasing water temperatures. What kind of impact might I expect along the coast? Due to the topography, in particular for southeast Alaska (less low lying areas), tidal flooding will generally not have a significant impact on the coast unless there is a severe storm.
              Lower than normal low tides will also occur.
 CARIBBEAN ISLANDS OUTLOOK
 Dates: The Caribbean Islands will not be significantly impacted. Locations: Tide stations at the following locations have the greatest chance of seeing high tide
            flooding: Caribbean Islands (Puerto Rico and U.S. Virgin Islands)
              Visit the NOAA Coastal Inundation Dashboard for this region to view real-time water levels with forecasts out to 48 hours.
 Why will they be higher than normal? This region will not be significantly impacted. What kind of impact might I expect along the coast? For Puerto Rico and the U.S. Virgin Islands, the tidal range is relatively small compared to other regions of the U.S, so these locations will not be significantly impacted by a perigean spring tide. However, local flooding may occur due to wave, rainfall, and elevated groundwater effects — particularly if there is a severe storm.
