Federal officials expect Boston will see around 11 to 18 days of "nuisance" flooding due to years of relative sea level increases.
High-tide flooding occurs when the average daily tide exceeds over 1.75 to 2 feet more than usual.
Experts said the cause of high tide can be sparked from moon tide or changes in prevailing winds.
In the last 20 years high-tide flooding has increased by about 50% and 100% in the last 30 years, according to the NOAA.
The NOAA's report showed that across all of New England, Boston is expected to be hit the hardest by the projected increase.
