Perigean full moon on October 26 raises high-tide flooding risk at Northeast and Mid-Atlantic harbors
NOAA's October high tide flooding outlook lists 43 harbors nationally with an elevated chance of nuisance flooding this month. Seven Northeast harbors and 10 Mid-Atlantic harbors are in the elevated-risk group, with the second and higher-risk spring-tide window arriving around October 26. Marina access roads, boat ramp staging areas, and waterfront parking in low-lying locations are the practical exposure points for anglers planning a late-October departure. Check tidesandcurrents.noaa.gov before driving to any coastal access point.
NOAA's High Tide Flooding Outlook for October 2026 lists 43 harbors nationally with an elevated chance of nuisance flooding this month. Seven harbors in the Northeast and 10 in the Mid-Atlantic are in the elevated-risk group. The second and higher-risk spring-tide window of the month arrives around October 26, when a perigean full moon brings the Moon to its closest point to Earth, amplifying the lunar tidal pull. High tide flooding at the nuisance level does not require a storm system; it can put water over low-lying marina access roads, boat ramp staging areas, and waterfront parking with no associated weather event.
A perigean full moon amplifies tides because two effects align: the Moon is full, putting the Sun, Earth, and Moon in near-alignment for spring tides, and simultaneously at perigee, where gravitational pull on ocean water is strongest. The combination raises predicted high tides above typical spring-tide levels. NOAA Tides and Currents publishes the monthly High Tide Flooding Outlook with harbor-by-harbor probability estimates at tidesandcurrents.noaa.gov/high-tide-flooding/annual-outlook.html. The predicted high tide for a specific port and date is available at the same site under the Tides and Currents portal.
For anglers planning a late-October departure, the practical questions are whether the marina lot, launch ramp, or access road at a listed harbor drains between tides and whether a saturated ramp creates problems for a loaded trailer. The NOAA outlook flags probability, not site-specific drainage conditions. A marina or launch site call after checking the outlook is the right step before driving to a coastal access point around the October 26 high tide.
Jetty tips, surf beaches, and backwater inlets are the most productive fall-run access points for striped bass, bluefish, false albacore, and tautog from southern New England through the Mid-Atlantic, and many of those locations sit on low-elevation approach roads subject to nuisance flooding. Check the specific tide prediction at tidesandcurrents.noaa.gov before any October 26 or 27 departure to or from a listed harbor. NOAA products are the pre-launch check; site conditions on the day may differ.
