The rising and falling of the sea is a phenomenon upon which we can always depend. Caused by the gravitational pull of the moon and the sun, tides are very long-period waves that move through the ocean and progress toward the coastlines where they appear as the regular rise and fall of the sea surface. 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 June, 2016.
NOTE: Higher than normal high tides alone generally do not cause significant flooding or negatively impact coastal areas. It is the combination of higher than normal water levels during these high tide periods and weather or wave conditions that leads to flooding and negative coastal impacts.
Several factors contribute to high tides:
Impacts due to coastal flooding include road closures, overwhelmed storm water systems, damage to transportation infrastructure, and coastal erosion.
This is the first of a new series of seasonal bulletins to let you know when you may experience higher than normal high tides. The next bulletin will be issued in the fall of 2016. NOAA is the nation's official source for tidal information.
