Peak bloom is reached when at least 70% of the Yoshino cherry blossoms are open. If the projections are correct, it will happen toward the midpoint of the National Cherry Blossom Festival, which spans from March 20 through April 13 this year. Once the trees hit peak bloom, they'll stay that way for about 10 days, according to FOX5 D.C.

The peak bloom date is "defined as the period when 70% of the Yoshino Cherry blossoms are open," according to the National Park Service.

The peak bloom dates for the iconic cherry blossoms in Washington, D.C. will be toward the end of March, the National Park Service announced on Thursday.
