The National Cherry Blossom Festival typically coincides with the “peak bloom” of D.C.’s cherry blossom trees, which Japan gave to the U.S. as a gift in 1912. According to the National Park Service, the average peak bloom date is in April.
The National Park Service estimates peak blooming period to around the weekend of March 25. The park service declined to give exact dates for the peak bloom. The park service has updated the predicted peak bloom several times throughout the season.
The peak time is defined as when 70 percent of the trees around the Tidal Basin will be in bloom.
