DC cherry blossoms are nearing peak bloom and where to see them.

Cherry trees around the National Mall are approaching peak bloom, which the National Park Service defines as 70% of flowers open and was expected around March 26; long-term records show peak dates have shifted earlier over past decades.

Around the National Mall in Washington, DC this week, cherry trees are moving toward peak bloom after an early warm spell followed by cold weather earlier in March. The National Park Service tracks six stages of flowering and defines peak bloom as the day when about 70% of the blossoms are fully open. The trees were a gift from Japan in 1912 and are the focal point of the National Cherry Blossom Festival. Scientists and long-term records note that bloom dates have tended to shift earlier over many decades, linked to warmer spring temperatures. Key details: - The National Park Service defines peak bloom as the day when roughly 70% of the cherry blossoms are in full flower. - Park updates posted on X reported many Yoshino cherry trees at the "puffy white" stage before rising temperatures could bring peak bloom. - Mike Litterst, communications chief for the National Mall and Memorial Parks, told USA TODAY peak bloom was expected by March 26. - About 3,000 cherry trees were gifted by Japan in 1912 and remain central to the National Cherry Blossom Festival. - Long-term data cited by the Environmental Protection Agency and observations from researchers show bloom dates have moved earlier by several days since the early 20th century, and trees respond strongly to late-winter and early-spring temperatures. Summary: Peak bloom timing and the length of the display depend on weather conditions, with calm, cool weather extending bloom and rain or wind shortening it. Expect the situation to be monitored by park officials and referenced in historical records, and the immediate outlook for bloom duration is influenced by current and near-term weather.
