While only San Diego and Nawiliwili, on the Hawaiian island of Kauai, are likely to see flooding in June, flooding is possible in every region of the mainland U.S. except the mid-Atlantic this month.
Some West Coast locations will experience their highest tides of the year in June, and certain stations are predicted to exceed the high tide flooding threshold based on tides alone. (A storm occurring at this time would result in even more tidal flooding and coastal erosion.) Higher water levels are most likely on or around the new moon, on June 11, and the full moon, on June 25. In the Northeast, Southeast, and West Coast, tides will increase leading up to and after the June 20 Summer Solstice, due to the increased angle of the Sun relative to the Earth's equator. Mean sea level is typically higher in the summer due to changing weather patterns and increasing water temperatures.
Make sure to print out the tide chart for your part of the coast so that you can keep track of the water levels in your favorite harbors.
