These floods – also known as nuisance floods or sunny day floods – are caused by high tides and rain, not by large storms and hurricanes. Honolulu could see high-tide flooding one day per month by 2037 and as many as 20 days per month by 2047, researchers found. Boston, La Jolla and St. Petersburg could see anywhere between 5 and 15 high-tide flooding days per month by 2051. In 2019, there were more than 600 high-tide floods, according to the National Oceanic and Atmospheric Administration (NOAA). The US agency expects that high-tide flooding will occur between 25 and 75 times per year, depending on location.
