General Questions When will the Cherry Blossom Trees bloom?
The National Cherry Blossom Festival is planned to coincide as nearly as possible with the blooming of the trees. Peak Bloom Date is defined as the day in which 70 percent of the blossoms of the Yoshino Cherry trees are open. The date when the Yoshino cherry blossoms reach peak bloom varies from year to year, depending on weather conditions. The mean date of blooming is April 4, but nature is not always cooperative and the National Park Service horticulturists cannot make an accurate prediction much more than 10 days prior. The blooming period starts several days before the Peak Bloom Date and can last as long as 14 days; however, frost or high temperatures combined with wind and/or rain can shorten this period.
