Snap the Shore, Face the Future: Enter to Win the New Hampshire King Tide Contest, November 14-17, 2020

Portsmouth, NH – The New Hampshire Coastal Adaptation Workgroup (CAW) announces the return of the New Hampshire King Tide Contest on November 14-17, 2020, and is inviting members of the public to submit photos and videos documenting the higher-than-average tides expected along New Hampshire’s coast. The King Tide Contest aims to enhance public understanding of the possible effects of sea-level rise and help communities visualize and plan for future coastal flooding impacts.

Tides are the regular rise and fall of the sea caused by the gravitational pull of the moon and sun and their position relative to the earth. According to the National Oceanic and Atmospheric (NOAA) High Tide Bulletin for Fall 2020, extra high tides are forecast to occur in New Hampshire on November 14-17, 2020 largely because the new moon will be positioned closest to the earth (a phenomenon called a “perigean spring tide” and casually referred to as one of several “King Tides” that occur annually). Sea level is also generally higher in the early fall months in the Northeast due to warmer, expanding ocean water and changes in weather patterns, which contribute to these extra high tides. Official NOAA Tide Predictions indicate that the mid-morning and early afternoon high tides during the contest period will exceed 10 feet at the Hampton Harbor tide gauge in Hampton, N.H., and 11 feet at the Fort Point tide gauge in New Castle, N.H.   

Tidal water levels are increasing with sea-level rise due to the increased melting of land-based glaciers and ice sheets, and the expansion of ocean water as it warms. Paying attention to the effects of King Tides each year helps us better understand how sea-level rise will impact New Hampshire’s coastal communities and the state’s economy more regularly in the future. The November 14-17, 2020 King Tides may cause coastal flooding, especially in low-lying areas, especially if the extra high tides coincide with rainy and/or windy weather conditions. King Tide Contest participants are urged to exercise caution and avoid existing and potentially hazardous conditions; obey all road closures, barricades, and other public access restrictions; respect private property; and follow CDC COVID-19 guidelines.

Important contest details are summarized below. For complete contest rules, terms, and conditions, please visit the NHCAW website.
