| https://oceanservice.noaa.gov/news/high-tide-bulletin/fall-2020/ 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. Southeast outlook Includes North Carolina, South Carolina, Georgia, Eastern Florida coast. When will the tides be higher than normal? September 15-21 October. 14-21 November 13-18 Why will they be higher than normal? Mean sea level is generally higher in the fall in the Southeast due to changing weather patterns and typical short-term decreases in Gulf Stream transport. 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. In October and November, some locations along the Southeast coast are predicted to exceed the high tide flooding threshold based on tides alone. 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? Tide stations at the following locations have the greatest chance of seeing high tide flooding: Myrtle Beach, SC; Charleston, SC; Fort Pulaski, GA; Fernandina Beach, FL; Mayport, FL; Port Canaveral, FL |
