4. High Tide Bulletin: Summer 2019

High Tide Bulletin: Summer 2019 When you may experience higher than normal tides between June and August 2019.


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 June and August 2019.    Regional **outlook** Text Only
 Northeast
  Mid-Atlantic   
  Southeast
 Gulf Coast
   West Coast
 Pacific Islands
    Alaska **Northeast** outlook *Includes Maine, New Hampshire, Massachusetts, Connecticut, and  New York* When will the tides be higher than normal? July 31 - August 4
		 August 29 - September 2 Why will they be higher than normal? 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 typically higher due to changing weather patterns and increasing water temperatures. What kind of impact might I expect along the coast? Due to the topography of the northeast (less low lying areas),  tidal flooding will not likely cause widespread impact on the coast unless accompanied by storm or strong winds. Where might I expect high tide flooding? Coastal areas near the tide stations at Bar Harbor, ME; Portland, ME; Boston, MA; Providence, RI have the greatest chance of seeing high tide flooding.
 **Mid-Atlantic** outlook *Includes  New Jersey, Delaware, Pennsylvania, Maryland, District of Columbia, Virginia* When will the tides be higher than normal? July 31 - August 3
		  August 28 - September 2 Why will they be higher than normal? 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 typically higher 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. Where might I expect high tide flooding? Coastal areas near the tide stations at Bergen Pt, NY; Sandy Hook, NY; Atlantic City, NJ; Cape May, NJ have the greatest chance of seeing high tide flooding.
 **Southeast** outlook *Includes North Carolina, South Carolina, Georgia, Eastern Florida coast* When will the tides be higher than normal? July 31 - August 3
		  August 28 - September 2 Why will they be higher than normal? 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 typically higher 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. Where might I expect high tide flooding? Coastal areas near the tide stations at  Fernandina Beach, FL; Fort Pulaski, GA; Charleston, SC; Myrtle Beach, SC have the greatest chance of seeing high tide flooding.
 **Gulf Coast** outlook *Includes Texas, Louisiana, Mississippi, Alabama, Western Florida coast* When will the tides 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 *Includes California, Oregon, Washington State* When will the tides be higher than normal? July 1- 4
          July 29- August 2
          August 28 - 31 Why will they be higher than normal? 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 in the weeks 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 will be higher due to changing weather patterns and increasing water temperatures. Where might I expect High Tide Flooding? Coastal areas near the tide stations at San Diego, CA; La Jolla, CA; Santa Monica, CA have the greatest chance of seeing high tide flooding. What kind of impact might I expect along the coast? Minor tidal flooding along the coast, in particular in low-lying areas.
             If a local storm or large swell are present at this time, increased levels of tidal flooding and coastal erosion may occur.
             Lower than normal low tides will also occur.
 **Hawaii and the Pacific Islands** outlook *Includes Hawaii, Guam, American Samoa, Midway, Kwajalein, and Wake Island* When will the tides be higher than normal? July 30 - August 3
              August 28 - September 2 Why will they be higher than normal? 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. Where might I expect High Tide Flooding? Areas near the tide station on Kwajalein, Marshall Islands have the greatest chance of seeing high tide flooding.
 **ALASKA** outlook When will the tides be higher than normal? August 1-4
            August 30 - September 3 Why will they be higher than normal? 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. 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.
 This year’s report summarizing the *high tide flooding events in 2017* and our *high tide flooding outlook for 2018* is now available. The latest report is based on new, national flooding thresholds. It focuses on more impactful, deeper floods at some locations and expands the outlook to about 100 coastal locations.
