Washington, D.C. — The National Park Service says peak bloom for the iconic cherry trees around the Tidal Basin and National Mall is expected between March 29 and April 1, though exact timing will depend on weather conditions.
Once peak bloom begins, the blossoms typically remain on the trees for about seven to 10 days. The annual bloom traces back to 1912, when Japan gifted 3,000 cherry trees to the United States. The trees have since become a springtime tradition in the nation’s capital, drawing millions of visitors each year.
In 2026, the bloom will coincide with preparations for the 250th anniversary of American independence as well as ongoing restoration work around the Tidal Basin.
The Interior Department said a $113 million project to restore the Tidal Basin and West Potomac Park seawall is nearing completion ahead of schedule. The work addresses flooding, sinking ground and aging infrastructure while helping protect the cherry trees and nearby memorials.
Because of the restoration project, walkways along part of the Tidal Basin between the Jefferson Memorial and the Franklin Delano Roosevelt Memorial will remain closed during the bloom period. Officials said clearly marked alternate routes will remain available and visitors can still walk the full loop around the basin.
When is peak bloom?
The peak bloom date is defined as the day when 70% of the Yoshino Cherry (Prunus x yedoensis) blossoms are open. Peak bloom varies annually depending on weather conditions. The most likely time to reach peak bloom is between the last week of March and the first week of April. Extraordinary warm or cool temperatures have resulted in peak bloom as early as March 15 (1990) and as late as April 18 (1958).
How long is peak bloom?
The Yoshino trees typically bloom for a period of several days. The length of the blooming period depends on weather conditions. Cool, calm weather can extend the length of the bloom, and a rainy, windy day can bring an abrupt end to the ephemeral blossoms. A late frost can prevent the trees from blooming at all.
Predicting the bloom.
Forecasting peak bloom is almost impossible more than 10 days in advance. The cherry trees’ blossom development is dependent on weather conditions. National Park Service horticulturists monitor bud development and report the status of the blossoms.
