NOAA High Tide Bulletin
          Fall 2022: When you may experience higher than normal tides
              between **September and November of 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 September and November 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 September
                          October 9-11
                          October 26-28
                          November 23-26 Locations: Tide stations at the following locations have the greatest chance of seeing high tide flooding: Bar Harbor, Maine; Portland, Maine; Boston, Massachusetts; Bridgeport, Connecticut; Kings Point, New York
                            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 November, 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.
                            
                            Mean sea level is generally higher in the early fall months due to warmer, expanding ocean water and changes in weather patterns. 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: September 7-10
                          October 9-12
                          October 26-29
                          November 24-26 Locations: Tide stations at the following locations have the greatest chance of seeing high tide

              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 September and November, a perigean spring tide will occur. 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.
             
           Mean sea level is generally higher in the early fall months due to warmer, expanding ocean water and changes in weather patterns. What kind of impact might I expect along the coast? 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.
 SOUTHEAST OUTLOOK
 Dates: September 8-10
              October 9-12
              October 25-30
                 November 23-26 Locations: Tide stations at the following locations have the greatest chance of seeing high tide flooding: Duck, North Carolina; Charleston, South Carolina; Fort Pulaski, Georgia; Fernandina Beach, Florida; Trident Pier, Florida
              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 September and November, a perigean spring tide will occur. 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 September-November 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 September-October 2022
                November 22-27 Locations: Tide stations at the following locations have the greatest chance of seeing high tide flooding: Friday Harbor, Washington; Port Angeles, Washington; Toke Point, Washington; South Beach, Oregon; Humboldt Bay, California
                  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 November, a perigean spring tide will occur. 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. 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.
 PACIFIC ISLANDS OUTLOOK
 Dates: September 7-12
            No dates in October
            November 24-26 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 September and November, a perigean spring tide will occur. 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. 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 in September
			October 26-28
			November 23-26 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 November, a perigean spring tide will occur. 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. What kind of impact might I expect along the coast? Due to the topography, particularly in 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? The Caribbean Islands will not be significantly impacted. Why won’t they be impacted? 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.
